Safety Precautions & Declared Material

General Equipment Precautions

Use of controls, adjustments, or performing procedures other than those specified herein, may result in hazardous radiation exposure.

When working with a FibeAir IDU, note the following risk of electric shock and energy hazard: Disconnecting one power supply disconnects only one power supply module. To isolate the unit completely, disconnect all power supplies.

Machine noise information order - 3. GPSGV, the highest sound pressure level amounts to 70 dB (A) or less, in accordance with ISO EN 7779.

Static electricity may cause body harm, as well as harm to electronic components inside the device.

Anyone responsible for the installation or maintenance of the FibeAir IDU must use an ESD Wrist Strap.

ESD protection measures must be observed when touching the IDU.

To prevent damage, before touching components inside the device, all electrostatic must be discharged from both personnel and tools.

In Norway and Sweden:

Equipment connected to the protective earthing of the building installation through the mains connection or through other equipment with a connection to protective earthing – and to a cable distribution system using coaxial cable, may in some circumstances create a fire hazard. Connection to a cable distribution system has therefore to be provided through a device providing electrical isolation below a certain frequency range (galvanic isolator, see EN 60728-11).

Utstyr som er koplet til beskyttelsesjord via nettplugg og/eller via annet jordtilkoplet utstyr – og er tilkoplet et kabel-TV nett, kan forårsake brannfare. For å unngå dette skal det ved tilkopling av utstyret til kabel-TV nettet installeres en galvanisk isolator mellom utstyret og kabel- TV nettet.

Utrustning som är kopplad till skyddsjord via jordat vägguttag och/eller via annan utrustning och samtidigt är kopplad till kabel-TV nät kan i vissa fall medfőra risk főr brand. Főr att undvika detta skall vid anslutning av utrustningen till kabel-TV nät galvanisk isolator finnas mellan utrustningen och kabel-TV nätet.

The FibeAir IP-10 IDU can be installed in a standard 19" ETSI rack as shown in the following illustration.

As shown in the illustration, four screws, supplied with the installation kit, are used to secure the IDU to the rack.



7.7 Installing the IDU in a Nodal Enclosure

Each IP-10 IDU in a nodal configuration operates as either the main unit or an extension unit. The IDU’s role is determined by its position in the nodal enclosure, with the lowest unit in the enclosure (Unit Number 1) always serving as the main unit.

The main unit performs the following functions:

Provides a central controller for management

Provides radio and line interfaces

Extension units provide radio and line interfaces, and are accessed through the main unit.

7.7.1 Nodal Enclosure Design

Two types of shelves are available for a nodal configuration:

Main Nodal Enclosure – Each node must have a main nodal enclosure, which can hold two IP-10 IDUs.

Extension Nodal Enclosure –Up to two extension nodal enclosures can be stacked on top of the main nodal enclosure. Each extension nodal enclosure can contain two IP-10 IDUs.

Main Nodal Enclosure

Extension Nodal Enclosure

Each nodal enclosure includes a backplane. The rear panel of an IP-10 IDU includes an extra connector for connection to the backplane. The following interfaces are implemented through the backplane:

and tighten it using 2 side screws.

Note If you remove the T-Card, the T-Card blank needs to be put back in the slot.

Important! For the warranty to be honored, install the unit in accordance with the instructions above.



7.8 Grounding the IDU and Electrical Information

The following illustration shows how the IDU is grounded to the rack.

IDU Grounding Notes

The IDU is suitable for installation in a Common Bonding Network (CBN).

Only copper wire should be used.

The wire must be at least 14 AWG.

Connector and connection surfaces must be plated. Bare conductors must be coated with antioxidant before crimp connections are made to the screws.

FibeAir provides a ground for each IDU, via a one-hole mounted lug onto a single-point stud. The stud must be installed using a UL-listed ring tongue terminal, and two star washers for anti-rotation.

For antenna ports, lightning protection is used that does not permit transients of a greater magnitude than the following:

Open Circuit: 1.2-50us 600V

Short Circuit: 8-20us 300A

The ampacity of the conductor connecting the IDU frame to the DC return conductor is equal to, or greater than, the ampacity of the associated DC return conductor.

1 On the IDU, connect a grounding wire to the single point stud below the IDU-RFU interface (using the single screw with two washers), and, at its other end, to the rack.

Single Point Stud

Grounding

Wire



2 Connect the power cable to the IDU power connector, and at the other end to the power source.

Note: Connecting the power cable to a live power source will cause the IDU to be powered on.

Important! Make sure to use a circuit breaker to protect the circuit from damage by short or overload.

Power Supply Notes

When selecting a power source, the following must be considered:

DC power can be from -40.5 VDC to -60 VDC.

Recommended: Availability of a UPS (Uninterrupted Power Source), battery backup, and emergency power generator.

Whether or not the power source provides constant power (i.e., power is secured on weekends or is shut off frequently and consistently).

The power supply must have grounding points on the AC and DC sides.

Caution!

The user power supply GND must be connected to the positive pole in the IDU power supply. Any other connection may cause damage to the system!

Power supply grounding should be in accordance with the following illustration:



7.8.1 Dual DC Feed

The dual feed IDU supports two DC inputs for power redundancy. Each input can be connected to a separate power source. The lower input is numbered 1, and the upper is numbered 2.

Each input can receive voltage in the range of -40.5Vto -60V.

Each power input has a dedicated LED on the front panel which indicates if that input is receiving adequate power. This means that the LED will be off when the input voltage is below -40.5V (absolute value).

In addition, the IDU raises an alarm when the power input is below the minimal level (one alarm per power input). You can mask this alarm using the CLI. This option can be used if you choose to connect only one power input and do not want a permanent alarm in the system.

The power input connectors have built-in screws. Appropriate DC cables should be used, and the screws should be fastened.

Connectors



8. RFU Overview

This section provides an overview of the radio frequency units (RFUs) that you can install as part of an IP-10 system. Ceragon's RFUs were designed with sturdiness, power, simplicity, and compatibility in mind. These advanced systems provide high-power transmission for short and long distances and can be assembled and installed quickly and easily. Any of the RFUs described in this section can be used in an IP-10 system.

FibeAir RFUs deliver the maximum capacity over 3.5-56 MHz channels with configurable modulation schemes from QPSK to 256QAM. The RFU supports low to high capacities for traditional voice, mission critical and for emerging Ethernet services, with any mix of interfaces, pure Ethernet, pure TDM or hybrid Ethernet and TDM interfaces (Native2).

High spectral efficiency is ensured using the same bandwidth for double the capacity, via a single carrier, with vertical and horizontal polarizations. This feature is implemented by a built-in Cross Polarization Interference Canceller (XPIC) mechanism.

An IP-10 system can use the following RFUs:

This section provides installation procedures for the following FibeAir RFU-HP systems:

Split Mount Installation

FibeAir RFU-HP 1+0/1+1 configuration

FibeAir RFU-HP 2+2 XPIC configuration

FibeAir RFU-HP N+1 configuration

All-Indoor Installation

FibeAir RFU-HP 1+0/1+1 configuration

Important Notes

The FibeAir system is to be installed in Network Telecommunication Facilities.

RFU-HP is intended for installation in a Restricted Access Location.

RFU-HP must be installed and permanently connected to protective earth by qualified service personnel in accordance with applicable national electrical codes.

10.1 About FibeAir RFU-HP

Ceragon’s FibeAir RFU-HP supports multiple capacities, frequencies, modulation schemes, and configurations for various network requirements. Its RF transceiver units operate in the frequency range of 6-11 GHz.

FibeAir RFU-HP capacities can be upgraded from 45 Mbps up to N x 155 Mbps.

For long distance links and backbone requirements, FibeAir RFU-HP offers Space Diversity functionality. Each transceiver can contain two receivers and one transmitter, which enable built-in diversity capability.

Built in Diversity in each transceiver increases the reliability of the link. In a 1+1/2+2 Hot Standby or N+1 configuration with Space Diversity, if a hardware failure occurs, the Diversity will not be affected.

FibeAir RFU-HP is installed in a Split-Mount configuration and All-Indoor horizontal configuration, as shown in the following example illustration.



FibeAir RFU-HP

10.2 About the FibeAir RFU-HP OCBs

FibeAir RFU-HP supports two types of OCBs:

OCB (Older Type)

New OCB

OCB (Older Type) New OCB

Note: This installation guide describes the installation of both types. You will need to verify which type you are using.

Both OCBs are compatible with the following RFU-HP RFU PNs:

RFU-HP RF Unit, fGHz 15HP-RFU-f RFU for Space Diversity split mount

RFU-HP Split 1Rx RF Unit, fGHz 15HPS-1R-RFU-f RFU for Non Space Diversity split mount

The main difference between the two types is the circulator direction. Depending on the configuration, OCB Type 1 or Type2 is used together with waveguide shorts, waveguide loads, U Bends, or couplers.



Each OCB has four waveguide access points: two in the front, and two at the rear. The diversity access point is optional.

If the system is not configured for diversity, all the relevant access points on the OCB must be terminated using waveguide shorts.

The two OCB types (with & without space diversity) have different part numbers.

10.2.1 OCB (Older Type)

OCB (Outdoor Circulator Block) has the following main purposes:

Hosts the circulators and the attached filters.

Routes the RF signal in the correct direction, through the filters and circulators.

Enables RFU connection to the Main and Diversity antennas.

Two types of OCBs can be used:

Type1 OCB

Type2 OCB

The main difference between the two types is the circulator direction. Depending on the configuration, OCB Type 1 or Type2 is used together with waveguide shorts, waveguide loads, U Bends, or couplers.

Each OCB has four waveguide access points: two in the front, and two at the rear. The diversity access point is optional.

If the system is not configured for diversity, all the relevant access points on the OCB must be terminated using waveguide shorts.

The two OCB types (with & without space diversity) have different part numbers.



The following block diagrams show the difference between the two OCBs and the additional Diversity Circ block which is added in some Diversity configurations.



10.2.2 New OCB

The new OCB has the following main purposes:

The OCB is optimized for Non Space Diversity (IFC) configuration, for Space Diversity (IFC) configuration, a diversity block is added.

Hosts the circulators and the attached filters.

Routes the RF signal through the filters and circulators toward the antenna port

Allows RFU connection to the Main and Diversity antennas.

The new OCB has just one type, and can be connected to an OCB via a flexible waveguide.

The new OCB connection is at the rear. It includes proprietary accessories (different than those used for the older OCB).

Each OCB has three waveguide access points: The In/Out port is located at the rear of the OCB.

The OCB ports include:

Tx port

Rx Port

Diversity port

If the system is not configured for diversity, all the relevant access points on the OCB must be terminated using waveguide shorts. Unused Rx ports will be terminated with a 50 ohm termination.

New OCB components include the following:

RF Filters

RF Filters are used for specific frequency channels and Tx/Rx separation. The filters are attached to the OCB, and each RFU contains one Rx and one Tx filter. In a Space Diversity configuration, with IF combining, each RFU contains two Rx filters (which combine the IF signals) and one Tx filter. The filters can be replaced without removing the OCB.

DCB (Diversity Circulator Block)

An external block which is added in Space Diversity configurations. The DCB is connected to the diversity port and can chain two OCBs.

Coupler Kit

The coupler kit is used for 1+1 Hot Standby configurations.

U Bend

The U Bend connects the chained DCB (Diversity Circulator Block) in N+1/N+ 0 configurations.



S Bend

The S Bend connects the chained OCB (Outdoor Circulator Block) in N+1 /N+ 0 configurations.

Pole Mount Kit

The Pole Mount Kit can fasten up to five OCBs and the RFUs to the pole. The kit enables fast and easy installation.

10.3 Installation Notes

WARNING!

The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or exposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 port as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

10.3.1 Grounding Notes

The RFU is suitable for installation in a Common Bonding Network (CBN).

Only copper wire should be used.

The coaxial port cables should be shielded and grounded at both ends.

The wire must be at least 14 AWG or thicker.

Connector and connection surfaces must be plated. Bare conductors must be coated with antioxidant before crimp connections are made to the screws.

FibeAir provides a ground for each drawer, via a one-hole mounted lug onto a single-point stud. The stud must be installed using a UL-listed ring tongue terminal, and two star washers for anti-rotation.

For antenna ports, lightning protection is used that does not permit transients of a greater magnitude than the following:

Open Circuit: 1.2-50us 600V

Short Circuit: 8-20us 300A

FibeAir’s battery return terminals are in the configuration of an Isolated DC return (DC-I) and Common DC Return (DC-C).



The grounding point is assembled as shown in the following illustration.

Branching Drawer Insertion



11.8 Configuring Correct TX and RX Frequency

Branching drawers should be assembled in accordance with link operating frequency (i.e., TX-Low or TX-High). As mentioned above, the branching drawer can be mounted in either direction in the chassis.

There are several types of branching drawers used for the different configurations. This section describes how to configure TX and RX settings when using each type of drawer.

Note that all explanations refer to the situation in which the chassis is in its upright position, indicated by the RFU-A IF cable connected at the left side. When the site or configuration mandates an inverted chassis installation, the indications should be referred to as if inverted.

1+0 with Chassis in Upright Position

1+0 with Chassis in Inverted Position

11.8.2 1+1 HSB Configuration (Upright)

11.8.3 2+0 SP Configuration (Upright)



11.8.4 4+0 SP Configuration

Note: In a 4+0 SP configuration, the LOWER chassis should be assembled in INVERTED position, to enable assembly of the U-bend. For more information, refer to configuration-specific instructions.

11.8.5 1+1 SD Configuration

Note: For this configuration, the top drawer has two versions (TX-High, TX-Low). The 1+1SD TX-Low drawer should be installed inverted at a TX-Low site.

For more information, refer to configuration-specific instructions.



11.9 Assembling Branching Elements

This section explains how to install L-bends, the termination, the U-bend, and the external coupler.

The L-bend has a negligible effect on RF performance. Its sole purpose is to enable easier connection of the elliptical waveguide going to and from the antenna. There are two types of L-bends (short and long) to enable easy mechanical connection of two antennas to two tightly assembled chassis.

The termination is a mandatory part which must be assembled to assure RF performance.

During upgrade procedures, the termination may be removed to enable branching expansion.

1 L-bend Type 1: At the rear of the chassis, connect the L-bend to the side of the circulators block marked TX OUT, using the screws and washers that are supplied.

2 Termination: At the rear of the chassis, connect the 50-ohm termination to the opposite side of the side of the chassis marked TX OUT (the expansion port), using the screws and washers that are supplied.

L-bend Type 1 and Termination Assembly



3 L-bend Type 2: When two chassis are connected together, connect L-bend Type 2 to the lower TX/RX port (marked TX OUT) to enable an easier elliptical waveguide connection to the lower TX/RX port.

L-bend Type 2 Assembly

Notes: To assemble the second termination to the lower circulator block as seen in the figure above, follow Step 2 above.

A complete assembly containing both types of L-bends and two terminations is presented in the figure below.

Complete L-Bend and Termination Assembly



4 U-bend: The U-bend is a specially designed, frequency dependant waveguide which is used to concatenate two RFU-A branching systems via the expansion port.

The mechanical connection of the U-bend is the same whether performed as part of an upgrade procedure or initial system configuration.

U-Bend Assembly

5 External Coupler: The external coupler is a specially designed coupler which enables vertical coupling between RFU-A units. The coupler is primarily designed for a non-traffic effecting upgrade scenario from a 1+1 to a 2+2 SP configuration, but can also be used in other scenarios.

The external coupler is connected in a two chassis configuration. It should be connected vertically, as shown in the figure below, to both of the ports marked TX-OUT, using the screws that are supplied.



External Coupler Assembly

11.10 Connecting the IF Cable

11.13.5 2+0 DP (2+0 Dual Polarization) OR 1+1SD-ST (Space Diversity Split Transmitter)

Notes: From a branching point of view, the difference between the 2+0 DP and 1+1SD-ST configurations is the origin of the waveguides connected to each of the L-bends.

Although in a 2+0 DP configuration the waveguides are connected to H and V-feeds from the same antenna (V and H), in a 1+1SD-ST configuration, each L-bend is connected to a different antenna using a single polarization.

The non-branching related difference is a different user configuration of the data unit: Either XPIC for 2+0 DP or 1+1 SD base band switching for 1+1SD-ST.

1 Assemble two empty chassis inside the rack, one above the other with none of the chassis inverted.

2 Connect the L-bends and terminations.

11.13.8 East/West Installation – for Every Configuration

Every configuration explained in this guide can also be installed for East/West(E/W). Mechanical facilitation of E/W installation introduces the waveguide clearance challenge, as two sets of waveguides must be installed in the same rack.

To support the E/W configuration in this respect, one of the sets (East or West) should be installed mechanically inverted to enable mechanical waveguide clearance.

The following drawings demonstrate this concept:

2+0 DP - Regular Configuration 2+0 DP - East/West Configuration

Mounted 1-Foot Antenna



13.6.2 Installation Instructions

WARNING!

It is important to mount the antenna exactly as described in this installation instruction. Ceragon Networks disclaims any responsibility for the result of improper or unsafe installation. These installation instructions have been written for qualified, skilled personnel.

Refer to the following figure while performing the installation.

Antenna Assembly - 1-Foot Antenna



1 Place U bolt (A) and safety collar (B) around the pole at the desired height, connect them and tighten in place at a 90 angle to the opposing site direction.

Note: The safety collar assembly shown in the figure above ((A) and (B)) is used to align and support the antenna mount during installation and antenna alignment. Once the mount is in place and alignment is completed, all bolted joints of the antenna mount are tightened and there is no further need for the support provided by the safety collar assembly. It may then be removed for use in future installations.



2 Connect (C) to (D) at the approximate elevation needed to face the opposing RFU (determined by the bolts fastened to part (C)).

3 Place the assembly constructed above ((C) and (D)) and U bolt (E) around the pole on the safety assembly (attached in Step 1) and connect the two. Before doing this, make sure that the elevation spindle (F) is in hole (G) and loosen the screws on both sides to grant freedom of movement.



After step 3, the assembly should be as illustrated in the following figure.

4 Attach the antenna (H) to the antenna mount (I).



Install the antenna with the drain plug side up as shown in the following figure.

Correct Orientation of Antenna

5 Mount the optical viewfinder on the antenna (optional). Locate the opposite site through the viewfinder and loosely tighten the bolts.

6 Roughly align the antenna with the opposing site. This can be done using compass bearings or visually.

Tip: It is sometimes difficult to identify the opposing site. For this reason, it is sometimes helpful to have someone at the opposing site use a reflecting device, such as a hand-held mirror, to reflect sun light towards you. The optical viewfinder can help in initial antenna alignment.



7 Insert the azimuth spindle (J) into hole (K) and tighten in place.

8 Attach the RFU to the mount assembly using the four latches on the RFU (L). See the following figure.

WARNING!

To verify proper sealing, confirm existence of a rubber O-ring on the antenna, as shown in the following figure.

Important: Apply silicon grease to the O-Ring groove to seal the contact point between the O-Ring unit and the RFU from water and other such elements.

Setting Polarization:

Polarization is determined by the orientation of the RFU. If the handle of the RFU is facing up or down then the polarity is vertical. If the handle of the RFU is to the side then the polarization is horizontal.

Tip: For easy installation and best weather immunity, mount the RFU so that the connectors are facing down.



9 Connect the coaxial cable between the IDU and RFU using the N-Type connector on the IDU and the RFU.

10 Make sure that the fittings and the coax cable are clean and dry. 11 Peel approximately 6 inches of COAX-SEAL from the paper backing. 12 Wrap isolation tape over the coax cover. Start winding from coax cover

towards fitting with one half overlap with each winding making sure all joints are well covered.

Wrapping the Isolation Tape



13 After entire fitting and coax cable are covered with approximately 3/16" thick layers, mold and form COAX-SEAL with fingers to make a smooth surface and force out any air.

Molding the Coaxial Seal

14 If more COAX-SEAL is necessary to complete seal, simply cut the needed amount and add to existing COAX-SEAL, molding and press into the other material. COAX-SEAL adheres to itself with slight pressure.

Carefully inspect seal to make certain that all joints are covered.

Important! Connect and disconnect the IDU from the RFU only when power is OFF.

15 Turn the IDU power switch ON.

13.6.3 Initial Antenna Alignment using the Headset

1 Connect the headset BNC adapter to the RFU. 2 Connect the headset to the adapter and put it on.

If a tone is heard, your initial alignment is OK. Now you can adjust the aim to find the highest tone pitch and proceed to the final alignment below.

If no tone is heard, the initial alignment is not satisfactory.

Tip: It is recommended to use the optical viewfinder for initial alignment. In this case, loosen the azimuth bolts, adjust azimuth and tighten in the position where the highest tone is heard. If this does not help, adjust elevation and then azimuth. See directions below.

Tip: It is recommended that two people perform this installation and alignment procedure, one at each RFU site, with the ability to communicate with each other.



13.6.4 Azimuth Alignment

1 Loosen the nuts shown in the following figure and rotate the antenna and mount, pointing it to the location of the opposing antenna.

2 Slowly sweep the antenna in azimuth using the azimuth adjustment nuts. 3 If the desired signal is not found, increase or decrease elevation setting

and repeat the azimuth sweep.

Adjusting Azimuth - 1-Foot Antenna (with safety collar)

13.6.5 Elevation Alignment

1 Loosen elevation adjustment bolts and nuts to adjust elevation (refer to the following figure).

2 Align pointer or edge of clamp with appropriate mark at the desired elevation reading.

3 Make an approximate setting. Temporarily tighten elevation bracket nuts.

Adjusting Elevation - 1-Foot Antenna



4 Once you attain the highest audible tone, disconnect the BNC headset adapter.

This completes initial alignment of the system.

13.7 Alignment Verification (checking actual receive level)

When pivoting the antenna 2 in azimuth and elevation during antenna alignment, three distinct lobes are probable: the two side lobes and the center (main) lobe.

To ensure optimum system performance, the center lobe of the antenna must be aligned with the center of the opposing antenna in the link.

The initial alignment procedure explained in the previous section allows you to align the system to the peak of a lobe. However, it is difficult to make sure that the system is aligned to the center lobe using the tone heard through the headset. Therefore, following the initial alignment procedure you must perform the final alignment verification explained below in order to make sure that the system is aligned to the center lobe by verifying that the actual received signal level corresponds to the expected receive signal level.

When the antenna is aligned to a side lobe, the expected RSL is at least 25 dB less than the calculated unfaded RSL.

Antenna Alignment - Main and Side Lobes

1 Connect a DVM (Digital Voltmeter) BNC adapter to the RFU. 2 Set the DVM to 2 VDC.



3 Turn the DVM on. The reading on the DVM indicates receive signal level. For example, if -1.44V is displayed, receive signal level is -44 dBm.

4 Compare the value displayed on the DVM to the expected value. 5 If the received signal level is within ±4 dB of the expected calculated level,

tighten all bolted joints and remove the safety assembly.

Warning

It is important to verify that the antenna is aligned to the center lobe peak. Proper alignment reduces the sensitivity to antenna movement, which can be due to strong winds or any other forces.



13.8 Final Check

When the antenna is installed, make sure that all aspects of the installation instructions have been followed. Check that all bolted joints are tightly locked, and connect and cover the coax cable connector as follows:

1 Connect the coaxial cable between the IDU and RFU using the N-Type connector.



Isolation Tape



6 If more COAX-SEAL is necessary to complete seal simply cut the needed amount and add to existing COAX-SEAL, molding and press into the other material. COAX-SEAL adheres to itself with slight pressure.




13.9 Safety and Grounding

The pole, antenna mount assembly, and feed cables must be grounded in accordance with current national and local electric codes to protect from surges due to nearby lightning strikes.

Clamps that provide a solid connection between ground wire and ground source should be used.

The antenna installation and initial alignment is now complete. Verify the installation using the process provided below and repeat this procedure for the antenna at the other end of the link.



14. Connecting an IDU to an RFU

An IDU is connected to an RFU by means of a coaxial cable between the N-Type connectors in the IDU and the RFU.

RFU Interface on IDU Front Panel

1 Connect the coaxial cable between the IDU and RFU using the N-Type connector.



Isolation Tape





6 If more COAX-SEAL is necessary to complete seal simply cut the needed amount and add to existing COAX-SEAL, molding and press into the other material. COAX-SEAL adheres to itself with slight pressure.


7 Route the Coax Cable from the IDU to the RFU and terminate it with N-type male connectors.

Note: Make sure you fasten the cable along the ladder!

Important! Make sure that the inner pin of the connector does not exceed the edge of the connector.

The cable should have a maximum attenuation of 30 dB at 350 MHz.

Management ports are connected to the switch (bridge) and are configured to Learning mode.

Note: Management ports can be configured to have one of the following capacities: 64kbps, 128kbps, 256kbps, 512kbps, 1024kbps, 2048kbps (default). Capacity is limited by the port ingress rate limit.

15.5.1 Configuring the Management Ports

1 In the Web-Based EMS, select Configuration > General > Management. The Management window is displayed.

2 From the bottom of the Management window, click Refresh. The current parameters are displayed.

3 In the Number of ports field, specify the number of ports that are used for management data.

4 When you are using In-band management, in the In-band Management VLAN ID field, specify the VLAN ID that is used to identify management traffic.

5 In the Type drop-down menu, select the management mode of operation: In band or Out of band.

6 In the Capacity drop-down menu, select the bandwidth that is allocated to the management port(s).

7 In the Auto negotiation drop-down menu, select one of the following options:



On - Enables this feature.

Off - Disables this feature.

8 In the Rate drop-down menu, select the bit rate you want for the management port(s).

9 In the Duplex drop-down menu, select Half or Full. 10 Click Apply. The parameters for the management port(s) are configured.

15.5.2 Management in a Nodal Configuration

In a nodal configuration, all management is carried out through the main unit, which communicates with the extension units via the nodal backplane. Therefore, management traffic must reach the main unit in order for management to be available.

A local craft terminal can be used to configure each IDU individually using CLI. However, with the exception of the main unit, functionality is limited to local configurations. Access to all other units is provided via the main unit’s CLI. For remote channels (e.g., Web-Based EMS, PolyView, and Telnet) this requires IP traffic to be directed to the main unit.

The IP address of the node is the address of the main unit in the node. In a 1+1 configuration, the node will have two IP addresses (the addresses of each of the main units) and should be managed via the Active unit.

15.5.3 Configuring Out-of-Band Management

With Out-of-Band management, the remote system is managed using the wayside channel. On both local and remote units, the wayside channel must be connected to a management port using an Ethernet cross-cable. The Wayside channel can be configured to Narrow capacity (~64kbps) or Wide capacity (~2Mbps). It is recommended to use Wide capacity in order to achieve better management performance.

15.5.3.1 Configuring the Wayside Channel

To configure the wayside channel capacity using the Web-Based EMS:

1 In the Web-Based EMS, select Configuration > Interfaces > Wayside Channel. The Wayside Channel page is displayed.

2 Click Refresh. The current settings for the wayside channel are displayed.



Web-Based EMS – Wayside Channel Page

3 From the Wayside admin drop-down menu, select Enable. 4 From the Capacity drop-down menu, select Narrow or Wide for the

wayside channel capacity. 5 From the Auto negotiation drop-down menu, select one of the following

options:

On - The system controls the data flow between the wayside channel and the other active ports.

Off - The data flow between the wayside channel and the other ports is not controlled by the system.

6 From the Duplex drop-down menu, select Full or Half duplex. 7 From the Rate drop-down menu, select the data rate for the port. 8 Click Apply. The settings for the Wayside Channel are configured.

Note: User Wayside channel and Enhanced Traffic Manager PTP optimized transport mode are mutual exclusive features. You should disable the PTP optimized transport mode before enabling the User Wayside channel. For instructions, refer to FibeAir IP-10 G-Series Web Based Management User Guide, DOC-00018688.



15.5.3.2 Out-of-Band Management in a 1+0 Link

At least two management ports are required for the local IDU. One port is for local management, and the second port must be connected to the Wayside port.

On the remote unit, the Wayside port must be connected to a management port.

1+0 Out-of-Band management via Wayside channel

15.5.3.3 Out-of-Band Management in a 1+1 Link

At the local site, the active and standby management ports can be connected to the host in either of the following ways:

Using an Ethernet splitter cable connected to an external switch

Using a Protection "Patch Panel"

The Wayside port must be connected to another available management port in each IDU. At the remote site, each IDU’s Wayside port should be connected to a management port.

1+1 Out-of-Band management via WSC (Cable Splitter)



1+1 Out-of-Band management via WSC (Patch Panel).

Note: It is possible to use fewer than three patch panels (as depicted above), according to the number of FE interfaces that need to be split (traffic, management, WSC), assuming the IDUs are co-located.

15.5.3.4 Nodal Configuration

In a nodal configuration, it is sometimes necessary to use external equipment in order to transport management to the main unit, as shown in the figure below.

Out-of-Band management in nodal configuration

15.5.4 Configuring In-Band Management

With In-Band management, the remote IDU is managed by specific frames that are sent as part of the traffic. These frames are identified as management frames by a special VLAN ID configured by the user. This VLAN ID must be used ONLY for management. It is NOT possible to configure more than a single VLAN ID for management. For instructions on how to configure the VLAN ID, refer to Configuring the Management Ports on page 257.

Important: It is highly recommended to classify the management VLAN ID to the highest queue, in order to ensure the ability to manage remote units even under congestion scenarios.



In-Band Management in 1+0 Link

The local unit is the gateway for In-Band management. The remote unit is managed via its traffic ports (the radio port, for example), so that no management ports are needed.

15.5.4.1 Configuring In-Band Management in a 1+1 Link

It is important to follow these instructions carefully in order to avoid management loss to the remote unit. It is mandatory to configure the same management VLAN ID in all units that are part of the same management domain.

In order to configure a protected link to In-Band management, or to change the management VLAN ID, the following steps must be performed, in order:

1 Configure the following units’ management VLAN ID in their order of appearance (even if the unit is still configured to Out-of-Band management):

Remote Standby

Remote Active

Local Standby

Local Active

Note: For instructions on how to configure the VLAN ID, refer to Configuring the Management Ports on page 257.

2 If Metro Switch is used, the Ethertype of the bridge should first be configured on the remote side of the link, then on the local side.

3 Configure all the units listed above to In-Band management. Again, this configuration should be made to the units in the order they are listed above.



1+1 In-Band Management (Cable Splitter)

1+1 In-Band Management (Patch Panel)

Note: It is possible to use fewer than three patch-panels (as depicted above), according to the number of FE interfaces required to be split (traffic, management, WSC), assuming the IDUs are co-located. When a patch panel is used, straight and short (<0.5m) Ethernet cables should be connected between the IDUs and the panel (these cables are provided by Ceragon). Straight Ethernet cables should be connected from the IDU to the patch-panel.



15.5.4.2 In-Band Management in Nodal Configurations

In a nodal configuration, it is necessary to transport management traffic to the main unit by using external Ethernet cables.

The following figures show a few examples of relevant topologies and how to connect the cables in each topology.

3:1 (Aggregation 3 to 1)

In-Band management in non-protected node

3:1 (Aggregation 3 to 1) with Protection



In-Band management in node with protected main units



15.5.4.3 GbE In-Band management in a node

In nodal configurations, the Ethernet bandwidth available between extension units and main units is limited by the Fast Ethernet interfaces to 100Mbps.

In order to achieve resiliency and have a configuration ready for higher bandwidth traffic, it is possible to set up the node in a ring configuration, using optical SFP connections between the IDUs as shown in the following figure.

15.5.4.4 In-Band Management Isolation in Single Pipe Mode

This feature is required by “carrier of carriers” customers that provide Ethernet leased lines to third party users. The third party user connects its equipment to the Ethernet interface of the IP-10, while all the other network interfaces, particularly the radios, are managed by the “carrier of carriers” user. In that case, management frames that are sent throughout the network to manage the “carrier of carrier” equipment must not egress the line interfaces that are used by the third party customer, since these frames will, in effect, spam the third party user network.



The following figure describes the management blocking scenario.

In switch modes, it is very easy to achieve the required functionality by a simple VLAN exclude configuration on the relevant ports. However, in Single Pipe mode, VLANs cannot be used to block traffic, since the line and radio interfaces are transparent by definition to all VLANs. Thus, this management blocking capacity is a special feature for Single Pipe applications that blocks management frames from egressing the line interface.

This feature is relevant only to Single Pipe applications. It is also relevant only to standalone units or the main unit in a nodal configuration. There is no purpose in blocking the In-Band management VLAN in extension units, since the management VLAN can be blocked in the Ethernet switch port.

Management isolation and blocking behavior is controlled by the block-management-towards-line CLI parameter. The default is disable. To enable this feature, enter:

block-management-towards-line disable

8 Click Apply. The script is activated.

15.6.5 Activating an Asymmetrical Script

To activate an asymmetrical script, you must upgrade the uplink script (narrow TX, wide RX) at one end of the link, and upgrade the downlink script (wide TX, narrow RX) at the other end of the link. This operation requires reset.

The number of TDM trails is determined by the capacity of the uplink (narrow script).

To avoid loss of management while upgrading the scripts, it is recommended to upgrade the remote side first.

Asymmetrical scripts are supported in both R2 and R3 hardware.



Notes: This feature requires an Asymmetrical Scripts license.

When using an asymmetrical script, the capacity license relates to the TX side of each link.

15.7 Configuring the Ethernet Switching Mode

FibeAir IP-10G supports Single Pipe, Managed Switch, and Metro Switch configurations. Single Pipe is the default configuration, and does not require a separate license. Configuring the system to Managed or Metro Switch requires a separate license.

15.7.1 Switch Configurations Overview

Single (Smart) Pipe allows only a single GbE interface for traffic (optical GbE-SFP or Electrical GBE, 10/100/1000 mbps). Traffic originating from any GbE interface is sent directly to the radio and vice versa. The Single Pipe method enables you to use QoS configurations. The Fast Ethernet interfaces (10/100 mbps) interfaces are "functional" interfaces (WSC, Protection, Management).

Managed Switch is a 802.1Q VLAN-aware bridge, allowing L2 switching based on VLANs. Each traffic port can be configured as an "access" port or a "trunk" port, as follows:

Type VLANs Allowed Ingress Frames Allowed Egress Frames

Access Specific VLAN should be

associated with the access port

Only untagged frames (or frames

tagged with VID=0 ("Priority

Tagged")

Untagged frames

Trunk

A range of VLANs or all VLANs

should be associated with the trunk

port

Only tagged frames Tagged frames

Hybrid

Specific VLAN is used for the

untagged frames

A range of VLANs are associated

with the tagged frames

Tagged and untagged frames Tagged frames

The Managed Switch method allows QoS configuration, and all Ethernet ports are allowed for traffic.

Metro Switch is an 802.1ad Provider Bridge, allowing Q-in-Q switching capabilities. Each traffic port can be assigned as a "Customer Network" port or a "Provider Network" port. The port attributes are listed in the following table:


Customer

Network

Specific S-VLAN should be

associated with the

customer network port

Untagged frames or tagged (C-

tag) frames

1 Disconnect all cables from the IDUs (radio, traffic, wayside, and protection), except for the management cable.

2 Turn on the Active unit. 3 Connect a management cable to the management interface of the Active

IDU, or configure the IDU via terminal:

i Install the license (if necessary). Refer to Loading a License Key on page 244.

ii Upgrade the software (if necessary). Refer to Upgrading the IDU Software on page 237.

iii Configure the radio parameters. Refer to Configuring the Radio Parameters on page 268.

iv Configure the security settings. Refer to 1 From the menu bar on the left side of the main management page in the Web-Based EMS, select Diagnostics & Maintenance > Configuration Management. The Configuration Management page is displayed.












Configuring the Security Settings on page 247. v Configure the Ethernet Application Type to set the Switching mode.

Possible values are Smart Pipe, Managed Switch, and Metro switch. Refer to Configuring the Ethernet Switching Mode on page 276.

4 Configure the required Management Type (Out-of-Band or In-Band). If you use In-Band management, configure a management VLAN ID. Refer to Configuring IDU Management on page 257.

5 For the Active IDU, set Protection Admin to: 1+1 HSB. At this point, management might be lost for approximately 50 seconds.

6 For the Active IDU, set Protection Lockout to: On. 7 Connect an Ethernet cross cable from the Protection interface of the Active

IDU to the Protection interface of the Standby IDU. 8 Turn on the Standby IDU. 9 Connect a management cable to the management interface of the Standby

IDU. 10 Perform the following configuration steps on the Standby IDU:



iii Configure the security settings. Refer to 1 From the menu bar on the left side of the main management page in the Web-Based EMS, select Diagnostics & Maintenance > Configuration Management. The Configuration Management page is displayed.












Configuring the Security Settings on page 247. iv Configure the Ethernet Application Type to the same Switching mode

as the Active IDU. Possible values are Smart Pipe, Managed Switch, and Metro switch. Refer to Configuring the Ethernet Switching Mode on page 276.

v If you are using Metro Switch, set its Ether Type to the same value as the Active unit’s Ether Type. Possible values are: 0x88a8, 0x8100, 0x9100 and 0x9200.

vi Configure the Standby IDU to the same Management Type as the Active IDU (Out-of-Band or In-Band). If you use In-Band management, configure a management VLAN ID. Refer to Configuring IDU Management on page 257.

11 For the Standby IDU, set Protection Admin to: 1+1 HSB. At this point, both units should start communicating, transmitting their local MAC & IP addresses to each other.

12 To verify communication between the two IDUs, check on both IDUs that there is no Mate Communication Failure alarm. If this alarm is active on either IDU, installation of 1+1 HSB Protection has failed.

13 The management cable can be disconnected from the Standby IDU. Use a Y splitter cable or the Protection Panel to connect both units’ management interfaces.



14 Check if there is a Configuration Mismatch alarm on either IDU. This alarm indicates that the IDUs do not have an identical configuration. If a Configuration Mismatch alarm is raised:

i Enter a Copy to Mate command on the Active IDU. This copies the configuration of the Active IDU to the Standby IDU.

ii Perform a Cold Reset on the Standby IDU. When the Standby IDU comes back online, its configuration should be identical to that of the Active IDU, and the Configuration Mismatch alarm should be cleared on both IDUs.

15 Connect all traffic, radio, wayside cables to both units (via protection panel, or via splitters).

16 Configure the Ethernet and E1/DS1 interfaces to Enable. 17 Perform a Copy to Mate operation to ensure that both IDUs remain

synchronized:



18 Disable “Protection Lockout” and verify that there are no alarms on either IDU.

19 Verify that the IDU connected to the RFU fed by the lower attenuation channel of the RF coupler is in Active mode. If this IDU is in Standby mode, enter a Manual Switch command.

Note: The same procedure should be performed on the remote end while installing the radio.

16.1.2 Replacing the Standby Unit in a 1+1 HSB Standalone System

13 Verify that new Standby IDU is set to Standby mode. 14 Connect all traffic, radio, and WSC cables to the new Standby IDU. 15 Check if there is a Configuration Mismatch alarm on either IDU. This alarm

indicates that the IDUs do not have an identical configuration. To remedy this:



16 For the Active IDU, set Protection Lockout to: Off.

16.2 Configuring 1+1 Space Diversity (BBS)

Space Diversity is a common way to negate the effects of fading caused by multipath phenomena. By placing two separate antennas at a sufficient distance from one another, it is statistically likely that if one antenna suffers from fading caused by signal reflection, the other antenna will continue to receive a viable signal.

IP-10 offers two methods of Space Diversity:

Baseband Switching (BBS) – Each IDU receives a separate signal from a separate antenna. Each IDU compares each of the received signals, and enables the bitstream coming from the receiver with the best signal. Switchover is errorless (“hitless switching”).

IF Combining (IFC) – Signals from two separate antennas are combined in phase with each other to maximize the signal to noise ratio. IF Combining is performed in the RFU.



Note: IFC Space Diversity is configured in the RFU, and requires a 1500HP RFU.

For BBS Space Diversity, the antennas must be separated by approximately 10 to 20 meters. Any RFU type supported by IP-10 can be used in a BBS Space Diversity configuration. Refer to RFU Selection Guide on page 29.

To enable BBS Space Diversity, the following features must be enabled for both IDUs:

Protection 1+1

Space Diversity

Note: BBS Space Diversity cannot be used together with Multi-Radio or Adaptive Coding and Modulation (ACM).

16.3 Configuring 1+1 Frequency Diversity (BBS)

Like Space Diversity, Frequency Diversity is a common way to negate the effects of fading caused by multipath phenomena. Frequency Diversity is implemented by configuring two RFUs to separate frequencies. The IDU selects and transmits the better signal. In the event of IDU failure, Frequency Diversity is lost until recovery, but the system remains protected through the ordinary switchover mechanism.

IP-10 implements Frequency Diversity via Baseband Switching (BBS).Each IDU receives a separate signal from a separate antenna. Each IDU compares each of the received signals, and enables the bitstream coming from the receiver with the best signal. Switchover is errorless (“hitless switching”).

BBS Frequency Diversity requires a 1+1 configuration in which there are two IDUs and two RFUs protecting each other at both ends of the link. Frequency Diversity is supported by the 1500HP and the RFU-HP RFUs. Each RFU in a Frequency Diversity node is configured to a different frequency.

To enable BBS Frequency Diversity, the following features must be enabled for both IDUs:

Protection 1+1

Frequency Diversity

In frequency diversity, ATPC and Green mode can be enabled on each RFU independently. You can enable and disable ATPC and Green mode, and can set thresholds on each IDU independently. Since radio channel fading may have a different impact on each frequency, it is recommended to allocate different fade margins for each frequency.

Note: BBS Frequency Diversity cannot be used together with Multi-Radio or Adaptive Coding and Modulation (ACM).



16.4 Configuring 2+0

You can set up an IP-10 system in a 2+0 configuration. A 2+0 system enables you to use Cross Polarization Interference Canceller (XPIC), Multi-Radio, or both. For more information, refer to Configuring XPIC on page 304 and Configuring Multi Radio on page 307.

In a 2+0 configuration, each RFU is connected to an IDU via the IDU’s RFU interface.



16.5 Configuring 2+2 HSB

A 2+2 protection scheme must be implemented by means of a nodal configuration. A 2+2 configuration consists of two pairs of IP-10 IDUs, each inserted in its own main nodal enclosure, with a protection cable to connect the main IDUs in each node. Protection is performed between the pairs. At any given time, one pair is Active and the other is Standby. The Active IDUs transmit to the line and radio, and the standby outputs of the IDUs are set to mute.

A 2+2 scheme is only possible between units in the main nodal enclosure. Extension nodal enclosures (slots 3 through 6) cannot be used in a 2+2 configuration.

In order to deploy a 2+2 configuration, insert the two IDU pairs into separate main nodal enclosures, and connect a protection (RJ-45) cable between the lower IDUs (slot #1) using the protection connector on the front panel. Fast Ethernet, TDM, and optical SFPs must be split between both lower units and between both upper units.

There are three configuration options: protection disabled, 1+1 protection, and 2+2 protection. The configuration is separate in each of the four IDUs, and you must configure 2+2 in all four IDUs.

In a 2+2 configuration, a protection cable must be connected between the two nodes via the Protection interface (RJ45).

All four IDUs in a 2+2 configuration must be the same hardware type (part number) and must be configured to 2+2 protection mode. In addition, both master IDUs need to comply with the following requirements (as in a 1+1 configuration):

Same Ethernet switch application (Smart Pipe, Managed Switch, or Metro Switch).

Same management type (In-Band or Out-of-Band).

Same In-Band VLAN. This VLAN may not be used for traffic.

Different IP addresses within the same subnet.

2+2 external protection can work with or without XPIC, and with or without Multi-Radio. For more information, refer to Configuring XPIC on page 304 and Configuring Multi Radio on page 307. In particular, in this case, all four IDUs must be configured with the same script. Note that changing the script and radio frequencies in the lower IDU will be copied automatically to the upper IDU.

16.6 Configuring XPIC

Cross Polarization Interference Canceller (XPIC) is a feature that enables two radio carriers to use the same frequency with a polarity separation between them. Since they will never be completely orthogonal, some signal cancelation is required.

In addition, XPIC includes an automatic recovery mechanism that ensures that if one carrier fails, or a false signal is received, the mate carrier will not be affected. This mechanism also assures that when the failure is cleared both carriers will be operational.

XPIC can be used in a 2+0 or 2+2 configuration. XPIC can be, but does not have to be, used in conjunction with Multi-Radio. Refer to Configuring Multi Radio on page 307.

16.6.1 Conditions for XPIC

XPIC is achieved using two IDUs inserted in a main nodal enclosure. One IDU is used for the horizontal polarization and the other is used for the vertical polarization.

XPIC IDUs can be placed inside a main node or extension node in any of the following slots: 1 and 2 (main node), 3 and 4 (extension node), and 5 and 6 (second extension node). Slot 1 is the bottom slot in the main node. The data of each polarization is marked by a different value, so the modem cannot lock on the signal of the mate polarization.

When installing an XPIC system, each IDU and each RFU must be the same hardware type. In addition, each IDU on both sides of the link must be set to the same frequency. An appropriate alarm is raised if these requirements are not met.

In order to activate XPIC, an XPIC script should be selected during initial configuration. The same script must be used in all the IDUs on both sides of the link.

After changing a script, the IDU must be reset.

16.6.2 Antenna and RFU Installation

1 Install the dual polarization antenna and point it in the direction of the other site.

2 The antennas should be aligned in order to achieve the highest XPI (in absolute value) during installation, and no less than 25dB. Refer to Displaying XPI Values on page 305.

3 Install the two RFUs on a dual polarization antenna using the appropriate mounting kit, and mark the RFUs with V and H respectively.



16.6.2.1 IDU-RFU Cable Installation

1 Install two cables between the RFUs and the IDU. Note that cable length difference should not exceed 10 meters.

2 Mark the cables with V and H respectively, and make sure V is connected to the upper IDU and H is connected to the lower IDU. Mark both IDUs respectively.

3 Ceragon indicate that the Lower IP-10 (and in case of enclosure the Bottom slot) as the V and the upper as the H.

16.6.2.2 Antenna Alignment

1 Power up the lower IDU (V) on both ends of the link and configure it to the desired frequency channel, and using the XPIC script with the maximum power.

2 Align the antennas, one at a time, until the expected RSL is achieved. Make sure the RSL achieved is no more than +/-2 dB from the expected level.

16.6.2.3 Polarization Alignment

Polarization alignment is required to verify that the antenna feeds are adjusted, ensuring that the antenna XPD (Cross Polarization Discrimination) is achieved.

Polarization adjustment should only be performed on one antenna.

1 Disconnect the V cable from the V RFU and connect it to the H RFU. 2 Check the RSL achieved in the H RFU and compare it to the RSL achieved

by the V RFU. 3 Verify that the XPI (Cross Polarization Interference) is at least 25dB

where:

sites.both at used onspolarizati orthogonal with RSLLink RSL

XPOL

POL

XPOLPOL RSLRSLXPI

4 If the XPI is less than 25dB, adjust the feed polarization by opening the polarization screw and gently rotating the feed to minimize the RSLXPOL.

Note that polarization alignment is not always possible since the RSLXPOL might fall below the sensitivity threshold of the RFU.

16.6.3 Displaying XPI Values

The current XPI value can be displayed in the Web-Based Management application and the CLI (the value is valid only when the modem is locked on a signal).

Using CLI, enter the command xpi.

Using Web-Based Management:

To view the current XPI value, select Configuration > Radio > Radio Parameters from the menu bar on the left side of the main management page.



To view XPI performance for intervals of 15 minutes or daily, select PM & Counters > Radio > XPI from the menu bar on the left side of the main management page. The XPI Performance window is displayed.

XPI Performance Window



16.7 Configuring Multi Radio

Multi-Radio transmits up to 1 Gb of Ethernet traffic using two radio links. It does this by dividing an Ethernet stream into two streams and assembling these streams back into a single stream at the remote site. The splitting of Ethernet data takes place on the byte level, which is optimal in terms of capacity compared, for instance, to splitting at the packet level. In ACM mode, traffic is split optimally between the two channels based on the current rate of each channel.

Multi-Radio can be used in 2+0 and 2+2 configurations. In a 2+0 Multi-Radio configuration, the IDUs perform in master and slave mode in which each Multi-Radio channel can carry up to 500 Mbps, resulting in a total 1 Gbps capacity.

Another Multi-Radio option is 2+0 with Line Protection. 2+0 Multi-Radio with line protection supplies additional protection for the line interfaces, guaranteeing no single point of failure. In case of failure of any line interface, a protection switch is initiated.

Note: 2+0 Multi-Radio with Line Protection cannot be used with other protection configurations (1+1 HSB and 2+2 HSB).

Because the Multi Radio interface uses the nodal backplane, a nodal configuration is required for Multi Radio. Like XPIC, IDUs in Multi-Radio mode can be placed inside a main node or extension node in any of the following slots: 1 and 2 (main node), 3 and 4 (extension node), and 5 and 6 (second extension node). Slot 1 is the bottom slot in the main node.

Ethernet traffic should be connected only to the lower IDU in a Multi-Radio couple (slots 1, 3, or 5). TDM traffic can be connected to either slot.

Multi Radio can operate with both XPIC and ACM, and with any switching mode:

Smart Pipe

Managed Switch

Metro Switch

Note: Multi-Radio cannot be used together with BBS Space Diversity and Frequency Diversity.

In Multi-Radio mode, traffic is divided among the two carriers optimally at the radio frame level without requiring Ethernet Link Aggregation, and is not dependent on the number of MAC addresses, the number of traffic flows or on their momentary traffic capacity. During fading events which cause ACM modulation changes, each carrier fluctuates independently with hitless switchovers between modulations, increasing capacity over a given bandwidth and maximizing spectrum utilization.

The result is 100% utilization of radio resources in which the Multi-Radio traffic load is balanced based on the immediate radio capacity per carrier.

In the event that one channel goes down due to a fault or a fade condition, the system automatically switches to work with the remaining channel using a graceful degradation mechanism.



Multi Radio requires that every IDU in the system be configured with Multi Radio Enabled. Each unit must also use the same script and the same hardware version.

In the case of Multi-Radio 2+0 with line protection every IDU in the system must be configured with 2+0 with line protection enabled. As with ordinary Multi-Radio, each unit must use the same script and the same hardware version.

16.8 Changing from 1+1 to 2+2

In order to change the configuration from 1+1 to 2+2 (and vice versa), the system must go through “protection disabled” mode. To switch between configurations, consult the following table:

From\To Disable 1+1 2+2

Disable No reset Slot#1 no reset

Slot#2 reset No reset

1+1 Slot#1 no reset

Slot#2 reset No reset Blocked

2+2 No reset Blocked No reset

The following procedures should be performed when changing units in a 2+2 node:

16.8.1 Replacing Slave Units (Extensions)

1 Set the master IDU in the Active pair to protection lockout:

Using Web-Based Management, from the menu bar on the left side of the main management page, select Configuration > Protection > Protection Parameters, and in the Protection Lockout field, select On from the drop-down list.

Using CLI, enter the protection-lockout command.



2 Insert the new IDU. 3 Power up the new IDU.

10 Connect the RFU to the new IDU.

Note that the force switch and protection lockout commands are performed in the master IDUs only. Copy to mate commands are available in master and slave IDUs separately.

16.9 Configuring Multi-Unit LAG

Multi Unit LAG provides Ethernet line protection for the Gigabit Ethernet (GbE) electrical and optical interfaces.

Multi-Unit LAG is supported with any of the following protection features:

1+1 HSB

1+1 Space or Frequency Diversity

2+2 HSB

2+0 Multi Radio with line protection

Multi-Unit LAG is only supported in Single Pipe mode.

Multi-Unit LAG is supported in both standalone and nodal configurations.

Multi-Unit LAG supports both electrical and optical interfaces.

In Multi-Unit LAG, an external switch is connected to the HSB protected IP-10 link by means of two static Link Aggregation (LAG) ports. The external switch can be another IP-10 IDU or any third party equipment that supports static LAG protocol.



External

Ethernet port 2

(mirroring)Ethernet port 1

The first LAG port of the external switch is connected to Ethernet port 1 of the active IP-10 unit and the second LAG port is connected to Ethernet port 1 of the standby IP-10 unit. Ethernet port 2 of the active IP-10 unit is connected to Ethernet port 2 of the standby IP-10 unit, as shown in the above figure. This port (port 2) is used for traffic mirroring, as described below.

In the uplink direction (toward the radio), the external switch splits the packets between the two LAG interfaces, which are connected to the active and standby IP-10 units. Ethernet packets received from the LAG interface in the active IP-10 unit are sent to the radio. Ethernet packets received from the LAG interface in the standby IP-10 unit are mirrored to the active IP-10 unit on port 2. The active unit receives these packets from port 2 and sends them to the radio.

In the downlink (from the radio), the active IP-10 unit receives Ethernet packets from the radio and forwards all of the packets to the External Switch through port 1.

To configure Multi-Unit LAG:

1 Enable protection. Each of the IP-10G protection features can work with Multi-Unit LAG.

2 Enable static LAG on the External switch. 3 Connect the External switch LAG interfaces to port 1 of the active and

standby IP-10 units respectively. 4 Connect Ethernet port 2 of the active IP-10 unit to the Ethernet port 2 of

the standby IP-10 unit. 5 Enable Multi-Unit LAG in the active IP-10 unit. Upon enabling, each IDU

will perform the following configurations automatically in both active and standby units:

Enable port 2.

Set a LAG on port 1 and port 2.

Enable mirroring.

6 Upon disabling Multi-Unit LAG, the configuration implemented in Step ‎0 will be disabled automatically.



In 2+2 HSB configuration, Multi-Unit LAG can be activated between slot 1 of the active nodal enclosure and slot 1 of the standby nodal enclosure and/or between slot 2 of the active nodal enclosure and slot 2 of the standby nodal enclosure, respectively.

Notes: As a constraint of the LAG protocol, port 1 and port 2 must have the same type of physical interface (e.g., both optical or both electrical).

To improve protection switchover delays, it is recommended to disable auto-negotiation and automatic state propagation on all the interfaces.

17.2 Site Acceptance Checklist Notes

The following notes provide important additional information about the Site Acceptance Checklist.

17.2.1 Antenna Mounting

Mounting pole is of sufficient height to clear local obstructions, such as parapets, window cleaning gantries, and lift housings.

Mounting Pole is of sufficient height, and is safely positioned, so as not to cause a safety hazard. No person should be able to walk in front of, or look directly into the path of the microwave radio beam. Where possible, the pole should be away from the edge of the building.

Mounting pole is secure and perpendicular. A pole that is not perpendicular may cause problems during antenna alignment.

Mounting pole is grounded as per site specifications. All operators and site owners have specific requirements regarding the grounding of installations. As a minimum, typical requirements are such that any metal structure must be connected to the existing lightning protection ground of the building. Where it extends beyond the 45 degree cone of protection of existing lightning conductors, additional lightning protectors should be installed.

All steelwork is Galvanized or Stainless Steel, as appropriate to prevent corrosion.



17.2.2 Antenna

Antenna is grounded as per site specifications. See the third point in the Antenna Mounting section above.

Antenna sway braces are fitted and installed correctly, where applicable. Typically, for an antenna of 1.2 m or larger, an extra sway brace is fitted to the mounting frame of the antenna. This sway brace should not be mounted to the same pole as the antenna, but should be installed directly back to the tower or an alternative point.

Antenna Water Drain Plugs are fitted and removed, where appropriate. Some antennas have moisture drain plugs installed at various points around the antenna. The purpose of these plugs is to allow any moisture that forms on the inside of the antenna or radome to drip out and prevent a pool within the antenna. Only the plugs at the bottom of the antenna, after installation, should be removed. All other plugs should be left in position.

17.2.3 RFU (Radio Frequency Unit)

The RFU is grounded as per installation instructions. See the third point in the Antenna Mounting section above.

The RFU polarization is as per link requirements and matches the polarization of the antenna.

17.3 IDU (Indoor Unit)

The main traffic connections are correctly terminated and crimped as per cable and connector manufacturer instructions. All fiber optic patch leads should be routed carefully and efficiently, using conduits to prevent damage to the cables.

All other user terminations are secure and correctly terminated.

All labeling is complete as per site requirements. Labeling is specific to each customer. At a site with only one installation, labeling may be unnecessary. However, at sites with multiple installations, correct and adequate labeling is essential for future maintenance operations.

Typical labeling requirements include:

Antenna labels - for link identity and bearing

RFU labels - for link identity, frequency, and polarization

Coax cable labels - for link identity, close to the RFU, IDU, and either end of any joint

IDU labels - for link identity

The CLI is used to perform IP-10 configuration and obtain system statistical and performance information.

Using the CLI, you can perform configuration operations for single IP-10 units, as well as configure several IP-10 units in a single batch command.

For more detailed information about the IP-10 CLI, refer to FibeAir® IP-10G CLI (Command Line Interface) User Guide, DOC-00023199 Rev a.04.

21.1 Access Rights

IP-10 CLI access is granted for the following user groups:

Viewer – This user only has read-only access. The user can only view parameters and their values, not modify them.

Operator – This user has read-write access. The user can read parameters and their values, and modify them. However, this user cannot add or remove other users.

Admin – This user has read-write access. The user can read parameters and their values, modify them, and add/remove other users.

Technician – This user has read-write access to the OS CLI.

User access is controlled by the system Administrator and configured via the Management command group. For further information, refer to Command Groups on page 351.

21.2 Getting Started

To log in to the CLI:

1 Power on your PC. 2 Make sure that your PC is connected to the management port on the front

panel of the IP-10 unit. 3 Open the telnet application, as follows: type telnet <IP address of the

unit>, Enter. 4 For a first-time login, use the following:

User: Admin

Password: Admin

Note: When using the Hyper Terminal, you should set the terminal speed (in your PC terminal configuration) to 155200 kbps. In addition, it is recommended to select the VT-100 terminal type and set the terminal size to 24 rows, 80 columns.



21.3 Getting Help

Once you are logged in, you can go to a main command group and its sub groups, type the command you want, and press Tab twice for a list of possible parameter values.

In addition, you can type a command and then type a question mark (?) for location-specific information for the command. For example, for the set command, typing set ? and pressing Enter will display a list of optional parameters and a help line.

Wherever you are in the command tree, you can obtain a list of available commands by typing Help or ?.

The commands that are available are different for each location in the CLI tree and the type of user.

21.4 Basic Commands

The following basic commands are available when you first log in, if you belong to the Operator user group:

ls list entities

get get parameter

set set parameter

help help

cd change directory

exit exit CLI

logout logout from CLI

cli-ver cli version

cls clear screen

write write the current switch configuration to the configuration file

show-tree show entity tree

find search for a string in the parameter name and information fields

lsp list entity parameters and commands

In addition, you can use the up/down arrow keys, or the “q” key, when the word “END” appears at the end of the screen.



21.5 Setting IP Addresses

To define a new IP address, do the following:

1 Log in as follows:

User: Admin or Operator

Password: Admin

2 At the command prompt, type: cd management\networking\ip-address\, and press Enter.

3 Type: get ip-address, and press Enter. 4 This will give you the current IP address. 5 Type: set new_ip_address, and press Enter. 6 For new_ip_address, enter the new address.

21.6 Finding Commands

At any point in the CLI tree, a quick way to find a command is to type find string, and press Enter. For string you can type any word that you think is relevant for a command.

For example, if you type find user, and press Enter, you would get a list of commands relating to "user", as follows:

1) management/mng-services/users/add-user Add user <name> <group>

2) management/mng-services/users/delete-user Delete user <name>

3) management/mng-services/users/show-users Show users



21.7 Command Example

The following example shows how you can find a command within a sub-group, and then execute the command. The example starts with the lsp (list parameters) command, and ends with the activation of an interface loopback test.

-----------------------------------------------

IP-10:/> cd diagnostics/loopback/radio-loopback/

IP-10:/diagnostics/loopback/radio-loopback> lsp

*********** configuration ********

timeout rw Loopback timeout in

minutes

*********** statuses *************

counter ro Loopback time left

if-loopback rw IF loopback activation

rfu-rf-loopback rw RFU RF Loopback Enable

Command

IP-10:/diagnostics/loopback/radio-loopback> set timeout 2

IP-10:/diagnostics/loopback/radio-loopback> set if-loopback

off on

IP-10:/diagnostics/loopback/radio-loopback> set if-loopback

on

Caution: This action affects traffic.

It may cause permanent loss of Ethernet traffic & wayside.

Consider disabling or physically disconnecting the Ethernet

ports of the IDM and Wayside before the loopback activation.

Are you sure? (yes/no):yes

IP-10:/diagnostics/loopback/radio-loopback>

-----------------------------------------------

Important! Note that bridge related commands need to be followed by a “write” command to be saved. Otherwise, the commands will not be saved following a reset in the system.



21.8 Viewing the Command Tree

At any location within the command group structure, you can type show-tree and press Enter for a list of all the commands in the group you are currently in.

The following list appears when you type show-tree.
