5 Installing the casings
Side fixing plates for
Earthquake Zone 4
Note:
The casings are pre-installed
with back covers.
In Earthquake Zone 4, the
maximum number of modules
for stack installations is five.
In pole and wall installations,
the maximum modules per
plinth is two.
In pole and wall installations,
maintenance straps must be
installed in the casings.
In Earthquake Zone 4, install
M5
X 8 screws should be

secured with thread locking
In Earthquake Zone 2, the
compound in pole and wall
maximum allowed height for
installations
a stack is 22U.
1. Align the holes of the first casing
bottom with the fixing studs
on the plinth
2. Push the casing back until it stops.
3. Attach the casing to the plinth with
M5 X 8 mm screws (6150279).
Tighten to 3.5-4.2 Nm
(2.58-3.10 ft-Ib)
4. Install the remaining casings as
required by the configuration
Check list
Back covers are properly installed.
Fixing screws are tightened.
Optional: In pole and wall installations, maintenance straps are installed in the front covers.
Installing the modules
Module installation principle
1. Slide the RF module and the System Module into the casings.
2. Attach the module(s) to the casing with M5 X 25 mm screws. Tighten to 3.5-4.2 Nm (2.58-3.10 ft-Ib).
3. Install the transmission sub-module to the System Module. Tighten to 2.7-3.3 Nm (1.99-2.43 ft-Ib).
4. Install the cable entries on both casings with M5 X 10 mm screws (6150240). Torque 3.5 to 4.2 Nm.
Note: In pole and wall installations, install the maintenance strap for back covers.
Check list
Module back covers and cable entries are installed.
Screws are tightened to the specified torque value.
Note: In pole and wall installations, screws are secured with thread locking compound.

front panel.
Cable Entry
2. Route the grounding cable through the cable entry.
3. Connect the other end of the cable to the plinth.
4. Repeat steps 1-3 with all the modules.
Tighten to 3.5-4.2 Nm (2.58-3.10 ft-Ib).
Check list
Modules are grounded.
Grounding connections are tightened to the correct torque values.
8 Cabling
Cable routing and cable ties
Cable entry
Cable clamp
Caution: Incorrect cables
and seals may not provide
secured environmental
protection.Use only tested
IP65 class cables with seals
provided by Nokia Siemens
Networks.
1. Route the cables through
cable entries.
2. Fix to cable tie points with
cable ties.
Cabling (continued)
External power cables
Connecting external power feed to system module
1. Install the cable clamp on the side of the
casing.
2. Remove the black rubber boots, nuts,
washers and cable lugs from the terminals.
3. Strip about 2 cm (.8 in) of insulation from
the (+) and (-) DC cables.
3 Strip off about 2 cm
4. Insert the stripped end of each cable into
a cable lug and crimp.

6a.Connect the (-) crimped wire to the
(-) connector pole, insert washer, and
tighten the nut. Connect the (+) crimped
wire to the (+) connector pole, insert
washer, and tighten the nut.
6a
6b.Torque the M10 nuts (max 14 Nm).
7. Pull the black rubber boots over the lugs.
6b
8. Route the cable through the external
cable entry.
9. Route the power cables through the
cable clamp, attach and tighten the cable
clamp screws with a T10 TORX
screwdriver.
Internal power cables
1. Remove the connector seal on the
module to uncover the connector.
2. Connect the cable to the System
Module.
3. Push the connector seal firmly
in place.
4. Connect the other end of the internal
power cable to the RF Module.
Push the cable connector seal
firmly in place.
Antenna cabling
1. Remove seals from the antenna
connectors. Store the connector
seals for later use.
2. Connect the cable to the antenna
connectors.
3. Route the antenna cables through
the cable entry.
4. Tighten the connector with a torque
wrench set to 25 Nm.
5. Repeat the previous steps for all
antenna cables required for your
configuration.
1. Remove the connector seal(s)
from the connector.
Transmission cables
2. Route the cable through the cable
entry.
3. Pull back the connector seal
covering the cable (Flexbus
connector excluded).
4. Connect the cable to the
appropriate connector.
5. Push the cable connector seal
firmly in place.
6. Repeat the previous steps for all
cables.
7. Make sure the that all the
connector seals are properly
installed.
Optical cabling
Caution: Overbending optical fiber cables
damages the cables and can detach or
damage the connectors. Do not bend
Left side
optical fiber cables to a radius smaller
than the minimum radius of 70 mm (3 inches).
