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.

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
installation and connection to customer termination equipment. Each ICP
can support one SM_10E traffic module. ICPs can be installed anywhere on

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.

AC Power Cable
An AC power cable is provided, fully prepared with the system. One AC powercable is required for a BG-20 shelf without the BG-20E, and two AC power
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.

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
