A-1200 Installation Manual 5 Cabling the device

5 Cabling the device

This chapter describes how to cable the device for connection to the network. It provides general and specific cabling information including:

• 5.1 "Cabling optical ports"

• 5.2 "Cabling 10/100/1000 Base-T copper cable access ports"

• 5.3 "Cabling the E1/T1 ports"

• 5.4 "Cabling the management ports"

• 5.5 "Cabling the alarm indicators"

When all of the network side and access side physical connections are complete, see Chapter 6, Powering up.

5.1 Cabling optical portsThis device uses lasers in its fiber optic ports. To ensure user safety, comply with the following precaution:

5.1.1 Recommended distances for 100/1000BASE-X (SFP) transceivers

When cabling 100/1000BASE-X transceivers, verify that the length of the fiber cable from the device to any attached device does not exceed the recommended distance.

5.1.2 Nokia Siemens Networks-approved transceivers

To ensure optimal compatibility, performance, and regulatory compliance, use only Nokia Siemens Networks supported transceivers and cables.

For a list of currently supported transceivers, contact your Nokia Siemens Networks representative.

5.1.3 Handling optical fibers

During testing and maintenance, some procedures require the handling of optical fibers that may be connected to optical transmitters. Under these circumstances, laser radiation within the limits of Class 1 might be present. Since Class 1 radiation is of sufficient magnitude to cause injury to personnel, caution must be used to avoid exposure. These precautions apply to any point in the system where the laser signal can be accessed.

The A-1200 can be powered up before it is cabled to test the device (staging the system). See Chapter 6, Powering up for an explanation of how to start the device before it is cabled.

WARNING: The fiber optic lasers used in the device meet the regulatory requirements for casual exposure to the eye. As with any source of bright light, however, Nokia Siemens Networks recommends not to look into the laser light source.

Only transceivers that use 3.3 VDC are supported.


5 Cabling the device A-1200 Installation Manual

When working with optical fibers, comply with the following precautions:

• Properly terminate all optical fiber jumper cable outputs before connecting the inputs.

• When using patch cords, make sure that the each ferrule is covered by its protective cap.

• Disconnect the input connector of the optical fiber jumper cable before disconnecting the output connector. Ensure that the optical fiber jumper cable output is safely terminated before reconnecting the input.

• Handle fibers with care. Glass fiber is subject to breakage if mishandled. Injury or permanent equipment damage can result from using broken fiber.

• Do not directly view the laser component of the modules from the output source, the output connector, or an unterminated fiber. The laser radiation can seriously damage your eyesight.

• Do not directly view the laser component of this product using an optical instrument without proper protective eyewear, filtering, or attenuation.

• Avoid physical exposure to the laser beam.

• Avoid direct exposure to fiber ends or optical connector ends that are in the laser's signal path.

• Place all optical fiber cuttings in a suitable container.

• Handle optical fibers with care. Keep them in a safe and secure location during installation.

• Protect unconnected optical fiber connectors with dust caps.

• Follow the manufacturer's instructions when using an optical test set. Incorrect calibration or control settings could result in hazardous levels of radiation.

5.1.4 Cabling optical network ports

For all network port cabling, keep the ports and connectors free of dust. See 7.5 "Cleaning dirty fiber optic ports and connectors" for details.

Be sure to follow all safety precautions when replacing an SFP transceiver in the device. To avoid electrical shocks and burns, and possible damage to the equipment, read and follow these warnings:

5.1.5 Cabling 100/1000 Base FX optical fiber access ports

Table 19 Event messages (continued)

To ensure optimal performance, compatibility, and regulatory compliance, use only SFP transceivers supported by Nokia Siemens Networks.

WARNING: The fiber optic lasers used in the device meet the regulatory requirements for casual exposure to the eye. As with any source of bright light, however, Nokia Siemens Networks recommends not to look into the laser light source.



To clean a fiber optic lens:

1 Remove any accumulated dust or debris from the port or connector by blowing across all surfaces with a canned air duster.

A compressed gas, such as Chemtronics’ Ultrajet or the Triangle Tool Group’s Liqui-Tool Dust-A-Way, is recommended. Do not use commercial compressed air or “house air” because of the risk of oil contamination.

2 Reconnect the cable to the port to check whether dusting has corrected the problem.

3 Gently wipe the ports with a lint-free, nonabrasive, nonadhesive swab. Microswabs by Texwipe are recommended.

4 Gently wipe the connectors with a lint-free, nonabrasive wipe or pad. Texwipe pads are recommended.

Avoid touching any connector surface after cleaning the connectors.


A-1200 Installation Manual 8 Quick setup for management access

8 Quick setup for management access

This chapter provides instructions for configuring the device for management access. When it has been decided how the device is to be managed, follow the configuration instructions for the preferred type of management access.

This chapter is intended to guide the user only through the initial management access and configuration of the management IP port.

A-1200 devices are configured and managed using the Command Line Interface (CLI). The CLI is a character-oriented user interface for administering the device. The CLI can be accessed through the Console port. For more detailed information, see the A-1200/A-2200 CLI User Manual.

A-1200 devices can be managed locally through a terminal connection or through the network with an IP connection. These mechanisms are described in the following sections.

8.1 Terminal connectionManaging the device locally through the console port is often preferred because it allows the user to remain in contact with the device during reboots. A workstation with a Macintosh or Windows operating system can use any terminal emulation program for connecting to the console port. A workstation with a UNIX operating system can use the emulator TIP.

To access the CLI using the console port:

1 Ensure that the terminal or terminal emulation program is configured with the following default settings for the console port:

– 115200 baud

– 8 bits

– 1 stop bit

– No parity

– No flow control

For more information on configuring the terminal or terminal emulation program, see the documentation that is shipped with the terminal or terminal emulation program.

2 Connect the terminal or the workstation running the terminal emulation program to the console port. For more details, see 5.4.1 "Cabling the console port".

3 At the login prompt, type the username. The password prompt appears.

4 At the password prompt, type the password. The user is logged in.

If a user does not have a username and password, a user with ‘admin’ level access can register the new user. See the A-1200/A-2200 CLI User Manual for the default username and password.


8 Quick setup for management access A-1200 Installation Manual

8.2 IP management interfaceAn IP interface is the connection between the device and the management network. Use the IP interface to manage the device in one of two ways:

• Out-of-band – Through the OOB management port. Only this port can be used to manage the device.

• In-band – Through a network port or access port of the device. The network port can be used for data transmission and managing the device simultaneously. An access port can be used for data transmission and managing the device simultaneously or just for management, depending on the configuration of the port.

8.2.1 Configuring out-of-band management access

To manage the device out-of-band, use CLI commands to configure the Host IP interface of the OOB port. For more information on using CLI commands, see the A-1200/A-2200 CLI User Manual.

To configure the Host IP interface:

1 Set the IP address, subnet mask, and default gateway using the following command:

config-set interface host-port ip <ip_address> <subnet_mask> <default_gateway>

where <ip_address> is the IP address in the format a.b.c.d, <subnet_mask> is the subnet mask in the format e.f.g.h, and <default_gateway> is the default gateway in the format i.j.k.l.

2 Define the default gateway:

config-set ip active-default-gateway host-port

3 Ping the management interface to ensure that it is active using the following command:

ping <ip_address>

where <ip_address> is the IP address of the management interface in the format a.b.c.d.

After the interface is configured, connect the device to the management station or network via the OOB port. See 5.4.2 "Cabling the out-of-band management port".

8.2.2 Configuring the in-band management access

To manage the device in-band, use CLI commands to configure a network or access port to allow in-band management. For more information on using CLI commands, see the A-1200/A-2200 CLI User Manual.


A-1200 Installation Manual 8 Quick setup for management access

To set up in-band management:

1 Configure the loopback IP address using the following command:

config-set interface loopback ip <ip_address> <subnet_mask> <default_gateway>

where <ip_address> is the IP address of the loopback interface in the format a.b.c.d, <subnet_mask> is the interface’s subnet mask in the format e.f.g.h, and <default_gateway> is the default gateway in the format i.j.k.l.

2 Define the default gateway as loopback:

config-set ip active-default-gateway loopback

3 Configure the management VLAN (if required):

config-set interface loopback management-vlan <vlan_id>

where <vlan_id> is the VLAN ID to be set as the in-band management VLAN.

4 Configure a UNI port for management access (only if you plan to use the device as a management access point in your network):

config-set interface ethernet <slot_port|if_num> management {tagged|untagged}

where <slot_port> is a the specific port on the specific module to be used as the access port.

5 Enable the port:

config-set interface ethernet <x> / <y> admin-state enabled

where <x> is the slot number and <y> is the port number of the access port.

6 To check this configuration, send a ping through the UNI port (that was attached to the management E-LAN) to the loopback IP address.

• Earthing is achieved through connection of the earthing terminal of the power supply to the earthed conductor of the central office power supply circuit using 18 AWG (minimum) green/yellow UL listed wire and lock or star washers for a secure connection. These markings may appear in the manual.

• Connect the DC power supply directly to the DC supply system earthing electrode conductor, or to a bonding jumper from an earthing terminal bar or bus to which the DC supply system earthing electrode is connected.

• There shall be no switching or disconnecting devices in the earthed circuit conductor between the DC source and the point of connection of the earthing electrode connector.

WARNING: Use of controls, adjustments, and procedures other than those specified herein may result in exposure to hazardous laser radiation. Therefore, you should avoid removing a Fiber Transition Module (FTM) unless absolutely necessary. If you do have to remove it for any reason, bear in mind that forced air flow must not be interrupted for more than two minutes in a system under power.


C Site requirements and safety codes A-1200 Installation Manual

C.2 Laser safety informationThe A-1200 devices use laser sources that emit light into fibers. This energy is within the red (visible) and infrared (invisible) parts of the electromagnetic spectrum. The maximum power propagating in the fiber is below 10 dBm, and the maximum modulation frequency is 1.25 Gbps. In the 1250 to 1620 nm range, the power can reach the maximum level of 10 dBm.

C.3 Laser safety precautionsBe sure to comply with the following laser safety precautions:

C.4 Site recommendationsThe cabling system plan at your facility probably covers most site concerns. Nokia Siemens Networks also recommends that the user check these items:

• Verify that the site meets all of the requirements in your facility cabling plan.

• Verify that the site and your facility meet all state, local, and country building and wiring codes.

• Be sure that the device is easily accessible for installation and service.

• Provide adequate overhead lighting for easy maintenance.

• Be sure that all doors providing access to the site have locks to prevent unauthorized access.

• Assign site identification numbers using architectural location codes or some type of floor-grid matrix.

• Select a vinyl floor covering for the site. Concrete floors accumulate dust; carpets can cause static electricity.

• Be sure that the floor is flat and level. If distribution racks are being used and the floor is not level, bolt the racks to the floor to prevent them from tipping over.

• When mounting the device in a rack, make sure that a hazardous condition is not produced due to uneven mechanical loading.

• Consideration should be given to the connection of the device to the supply circuit, and the effect that overloading of circuits might have on overcurrent

WARNING: This module contains Class 1 levels of radiation, as defined by the International Electrotechnical Commission (IEC). Class 1 levels of direct laser radiation are considered hazards to the skin and eyes.

WARNING: Do not look directly at the optical connector output beams when inserting or removing connectors. The beams can cause permanent eye damage.

WARNING: Use protective glasses such as the Laser-Gard® Green CO2 (LGE Spectacle, LGS Goggle, LWG Wraparound, or LGF Full-View) or an equivalent type of covering equipment with an optical density greater than 2. Eye protection must cover a wavelength of 800 to 1800 nm. See your laser safety officer for more information.



protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

• Be sure that each site has a suitable ground. Ground all metal racks, enclosures, boxes, and raceways.

• For AC power supply, use AC power, and 15 or 20-ampere service receptacles. Follow the other device specifications shown in Appendix A, A-1200 technical specifications.

• For DC power supply, use DC power.

• Be sure to meet all device environmental requirements in Appendix A, A-1200 technical specifications, such as ambient temperature and humidity.

• Be sure that the site’s ventilation is adequate to maintain a temperature below 45 °C (113 °F).

• If the device is being installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack may be greater than room ambient temperature. Therefore, consideration should be given to installing the device in an environment compatible with the maximum rated ambient temperature (as specified in Appendix A, A-1200 technical specifications).

• If the device is being installed in a rack, make sure that the amount of air flow required for safe operation of the equipment is not compromised.

• Install a reliable air conditioning and ventilation system if two or more devices are being installed at the same site.

• To prevent overheating during nonbusiness hours, guard against the ventilation being shut down while the device remains powered up.

C.5 Distribution rack requirementsBefore mounting the device in a distribution rack, verify that the rack meets the basic mechanical and space requirements described in this section.

C.5.1 Protective grounding for the rack

Reliable grounding of rack-mounted equipment should be maintained. Particular attention should be given to supply connections (such as power strips) that are not direct connections to the branch.

Proper distribution rack grounding ensures that voltages induced into wiring by lightning or other disturbances are directed to ground. Use a distribution rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground.

Install the distribution rack near an easily accessible power outlet. The user can power down the device only by removing the power cord from the power source or the device itself.

WARNING: The A-1200 device may have multiple power sources. Make sure to disconnect all power before servicing.



Space requirements for the rack

Make sure that there is sufficient clearance around the rack for service access, ventilation, cabling, and power supply entry, as specified in the following sections.

Service access

Provide sufficient space around the device so that it can be easily serviced, as shown in Table 21.

Ventilation

Table 22 shows the clearances necessary to ensure proper ventilation of the device.

Cabling

Provide sufficient space around the rack for cabling, as shown in Table 23.

C.5.2 Mechanical requirements for the rack

Verify that the racks comply with the standards and requirements in the cabling system plan and conform to these conventional standards:

• In the United States, comply with EIA Standard RS-310C: Racks, Panels, and Associated Equipment.

• In countries other than the United States, comply with IEC Standard 297: Dimensions of Panels and Racks.

In addition, Nokia Siemens Networks recommends that the distribution racks meet these requirements:

• Use an open style, 19-inch rack. The rack styles shown in Figure 23 facilitate easy maintenance and provide excellent ventilation.

If any device is located next to the A-1200 device, the clearances specified for that device should be added to the A-1200 device clearances listed below.

Ethernet A system for Local Area Network communication, originally developed by Digital, Xerox and Intel. This packet-based network system was accepted as a standard by IEEE (802.3).

Ethernet network access is controlled by the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol, in which a station that intends to transmit listens for other Ethernet traffic on the network. When the station does not detect network activity, the station transmits.

Ethernet supports three line speeds: 10 Mbps, 100 Mbps (Fast Ethernet), and 1000 Mbps (Gigabit Ethernet).

fiber optics A method for transmitting information (data, audio, graphic) as light pulses along hair-thin fibers of glass or plastic.

Optical fiber carries much more information than conventional copper wire, and is, in general, not subject to electromagnetic interference and the need to retransmit signals.

flash A type of nonvolatile memory that can be erased and reprogrammed in blocks.

FTP File Transfer Protocol. An application protocol used for transferring files between network nodes.

gateway A network point that acts as an entrance to another network.

Gigabit Ethernet One of three transmission speeds supported by Ethernet (see Ethernet above). Gigabit Ethernet supports transmission speeds of up to 1000 megabits per second.

interface The arrangement supporting the attachment of any device to a connector or to another device. There are two types of interfaces:

• Physical interface — A physical port to which a network cable can be attached. The other end of the cable is attached to a network device.

• Virtual interface — A virtual port that can connect to other interfaces using existing circuits.

IP address Internet Protocol (IP) is a standard network protocol that is used for communication among various networking devices. One of the requirements for using IP is assigning IP addresses to hosts (computers).

IP addresses are 32-bit addresses that consist of a network part (the address of the network where the host is located) and a host part (the address of the host on that network).

A central agency assigns the network part of the IP address, and the user assigns the host part. All devices that are connected to the same network share the same network part (also called the prefix).

link A communications channel or circuit.

MAC address Media Access Control address. A network element’s unique hardware number.

MIB (of SNMP) Management Information Base. A database of information on managed objects that defines what SNMP can manage within a device.
