Power SourcesBG-20 shelves can be powered by DC sources complying with the applicable

sections of ETSI 300 132-2 and the SELV or TNV requirements of EN 60950.

The nominal supply voltage is -48 VDC (positive-lead grounded). However,

the allowed supply voltage range is -40.5 VDC to -60 VDC. Power feeding forthe BG-20B shelf and the BG-20E shelf are separate. For redundancy, two

separate DC power sources should be available. In the DC power supply, the

maximum power consumption of the BG-20B is 50 W and the maximum

power consumption of the BG-20E is 130 W.

BG-20 shelves can also be powered directly from standard AC power outlets.

The nominal AC supply voltage is 220 V/50 Hz or 110 V/60 Hz. The allowed

range is 94 VAC to 240 VAC. In the AC power supply, power feeding for the

BG-20B and BG-20E shelves is separate. Because of the efficiency of the

AC/DC conversion in the AC power supply, the maximum power consumption

of the BG-20B is 62.5 W and the maximum power consumption of the BG-20E

is 162.5 W.

NOTE:If the planned power consumption of the equipmentinstalled in the shelf is 80% or more of the maximum listedvalue, it is recommended to consult ECI Telecom Customer

Support.

Typical BG-20 InstallationFor a typical installation of a BG-20 shelf in an ECI Telecoms ETSI rack, see

Typical installation of a single BG-20 shelf in a 2200 ETSI rack (page3-3). In

this figure, two BG-20 shelves are shown with the BG-20E and the other two

shelves are shown without the BG-20E.

In addition to the BG-20 itself, the equipment installed in the rack includes:

One RAP installed at the top of the rack. The RAP is used to connect

external power and alarm monitoring lines (RAP-4B only) to the BG-20

shelves installed in the rack. The RAP fully supports up to four shelves

with dual power feeding or eight shelves with single power feeding. In

addition to the space needed for RAP installation, you must leave at least

50 mm of free space under the RAP for cable routing.

NOTE: The RAP-BG does not support alarm monitoringlines.

Fiber Storage Tray. A separate FST can be installed for each BG-20 with

optical modules. Each FST contains two storage reels, enabling the fiber to

be stored on the right or left side of the tray. Leave at least 50 mm of free

space between the BG-20 shelf and its FST, and another 50 mm free

between the FST and the next BG-20 shelf.

BG-OW. An external box that adds an orderwire interface and functionality

to the BG-20. It can be installed on either the left or the right rail of the

rack. It should be installed in the most suitable place for convenient

operation.

xDDF-21. When unbalanced E1 interfaces are needed, the xDDF-21 should

be installed with the BG-20. Each xDDF-21 can support 21 channels of E1.

The xDDF-21 can be installed anywhere on the same rack on which the

BG-20 shelf is installed, or on another rack.

ICPs for the SM_10E, including ICP_VF, ICP_V24, ICP_V24F,

ICP_V11_V24, and ICP_V35. When PCM interfaces are provided by the

SM_10E, the corresponding ICPs can be installed in order to simplify

Maintenance Manual

Before You Start


Grounding Cables

Shelf grounding is achieved by connecting the shelf to the rack using rackmounting brackets. Grounding is provided by contact when the unit is fastened

to the rack.

A reliable low-impedance connection must be provided using copper

conductors between the rack frame and the site grounding bus.

Make the connection between the rack grounding screw and the site grounding

bus with a 2 AWG (35 mm2) or thicker copper lead with yellow/green

insulation, in compliance with UL/ETSI recommendations.

Route grounding conductors along the shortest possible route. Treat the bare

portion of the conductor with antioxidant and connect a listed two-hole

compression lug. If the lug is not plated, polish it until it has a bright finish and

coat it with antioxidant before connecting it to the frame of the rack. Do not

mix different types of metal conductors.

DC Power CablesDC power cables should be prepared on site. Two types of DC power cables

are needed:

RAP input power cables

Shelf power cables

ECI Telecom recommends the use of shielded power cables for DC powerconnections, with the shields connected to the frame ground at the rack end

only.

RAP Input Power Cables

The RAP input power cables are prepared on site. They connect input power

from the site power distribution subsystem to the DC input terminals of the

RAP.

Two input power cables are required for each rack, one for each source. The

cables must use copper leads complying with UL/ETSI recommendations. Use

a red lead for the positive conductor and a black lead for the negativeconductor. The RAP cable ends must be terminated in M6 cable lugs matching

the conductor gauge.

The recommended cable gauge is 25 mm2or thicker. This gauge ensures that

the voltage drop across the rack power cable does not exceed 2 V, even for

cable runs of maximum 30 meters connected to a RAP and providing power to

multiple BG-20 shelves.

cables are required for a BG-20 shelf with the BG-20E.

The AC power cable comes with an AC male connector for connection to the

AC source outlet. Replace the AC male connector if it is not suitable for the

local AC source.

Alarm CablesAlarm cables used within BG-20 equipment are included in the shipment

according to the site specifications.

The alarm indications are carried by the shelf alarm indication cable. One shelf

alarm indication cable is required for each BG-20 shelf installed in the rack.

This cable connects between the ALARMS connector on the BG-20B and one

of the ALARMS connectors on the RAP (RAP-4B only). Cable length is 2.0 m.

NOTE: There are no ALARMS connectors on the RAP-BG.

Management CablesOut-of-band management traffic is connected to a BG-20 shelf via the RJ-45

(MNG) connector located on the front panel of the BG-20B.

The MNG Ethernet connector is wired as a 10BaseT station port for direct

connection through an RJ-45-to-RJ-45 straight cable to a port of a 10BaseT

Ethernet hub.

Suitable standard Ethernet station cables are available from many sources.

Cables of Category 5 or better must be used. In all cases, the length of the

cables must not exceed the maximum recommended for the cable type and hub

port in use (up to a few dozen meters).

Timing (Clock) CablesThe BG-20 shelf uses an RJ-45 connector on the BG-20B front panel that

integrates the two timing reference interfaces (2 x T3 and 2 x T4). If it has

balanced (120 ) G.703 interfaces, a multitwisted-pair cable with an RJ-45connector (supplied by ECI Telecom) is used to connect timing signals from

the BG-20 to the site timing reference distribution subsystems.

If the site timing reference distribution subsystem has unbalanced (75 ) G.703interfaces, an adapter with coaxial cables that provides balanced-to-unbalanced

conversion (supplied by ECI Telecom) should be configured.

Maintenance Manual


Avoid contact with high-voltage sources when installing platforms, cards,

and modules.

Make sure you are familiar with the warning signals and labels on theequipment and strictly observe the procedures needed to avoid the indicated

hazards.

Grounding RequirementsAll the equipment, including BG-20 platforms, ancillary units, and equipment

from other vendors, must be properly grounded at all times. Good equipment

grounding is necessary to protect personnel and equipment, minimize noise,

and allow the discharge of accumulated static charges to earth.

Rack Grounding Requirements

Connect the rack to the site grounding bar with a ground cable according to

ETSI recommendations (top/bottom connection).

The rack is supplied with a main copper or brass grounding bolt welded to the

rack frame. The grounding stud is identified on the rack by the ground symbol

label.

The rack grounding bolt must be connected to the site grounding bar by a 35

mm2(2 AWG) grounding cable or thicker, as short as possible, complying with

UL/ETSI recommendations. The bolt must be free of paint. The cable must be

made of copper strands and terminated on both sides with bolt terminals.

NOTE: If necessary, the gauge of the grounding lead can alsobe reduced to the gauge of the RAP power leads.

The rack mounting rails must be free of paint and provide electrical continuity

to the main grounding bolt. The resistance between any rail and the rack main

grounding bolt must be less than 0.1 .

Pay particular attention to the area in which the RAP is attached. Remove paint

from the rack in this area to ensure efficient electrical contact.

CAUTION: Connect the RAP grounding bolt to the rackgrounding bolt with a grounding cable complying withUL/ETSI recommendations. The cable must include bolt

terminals on both ends and be securely fastened with a nutand a star washer.

Power Supply Requirements

The BG-20B, BG-20E, and BG-20C-DC shelves require two power sourceswith a nominal voltage of -48 VDC. Each power source is protected by a

UL-listed circuit breaker installed in the RAP. The required circuit breakers are

included in the installation parts kit supplied with the equipment, and therefore,

their current rating is in accordance with the order.

The site operator must provide a readily accessible UL-listed disconnect device

incorporated in the fixed power wiring of the site. This device limits the

maximum delivered current to a safe value.

Protection Against Electrostatic

DischargeThis section provides guidelines regarding the protection of BG-20 equipment

and its components against electrostatic discharge (ESD) during handling,

packing/unpacking, transport, installation, commissioning, inspections,

servicing, and maintenance.

Electronic equipment, assemblies, and components that are ESDS (electrostatic

discharge sensitive) or include sensitive items are identified by the basic ESD

warning symbol shown in the following figure.

Figure 2-3: Basic ESD warning symbol

The information provided in this section is in line with CENELEC Electronic

Components Committee (CECC) specification CECC 00 015, which deals with

protection of devices sensitive to ESD.

Most types of electronic equipment, assemblies, and components can be

damaged by electrostatic discharges. An ESD between two objects occurs

when an object carrying static electrical charges touches or is brought near

another object.Static electrical charges appear as a result of friction between surfaces of

insulating materials or separation of two such surfaces, and may also be

induced by electrical fields. Routine activities such as walking across an

insulating floor, friction between garment parts, friction between objects, and

so on, can easily build up charges to levels that may cause damage, especially

when humidity is low.

In many cases, the build-up of charge can be avoided by using special

materials, for example, garments and packaging of antistatic materials or

materials that have high resistance, but yet are not insulators.

The best way to avoid damage by ESD is a combination of means and

procedures that achieves the following goals:

Avoids build-up of electrostatic charges

Creates a protected work environment that helps prevent ESD

Provides means for controlled discharge of any accumulated electrostatic

charges when entering the protected work environment
