(1) Filling (2) Core layer
Figure 5-19 Sealing module
Take out the filling when you install cables. You need to put it in the sealing
module when you are not using the module to separate cables.
The core layer is blue and black multi-layer rubber. You can strip each layer
by hand until the internal diameter of the module fits the cable, as shown in
Figure 5-20.
Figure 5-20 Stripping the core layer of the sealing module
There are three types of sealing modules:
– CM 15w40:15 mm (0.59 in.) x 40 mm (1.6 in.) x 30 mm (1.2 in.) (Length x
Width x Depth)
– CM 20w40: 20 mm (0.08 in.) x 40 mm (1.6 in.) x 30 mm (1.2 in.) (Length x
Width x Depth)
– CM 30w40: 30 mm (1.2 in.) x 40 mm (1.6 in.) x 30 mm (1.2 in.) (Length x
Width x Depth)

– A lot of cable installation positions are reserved in areas 3 and 4. You can lead in
the cable through the nearest sealing module.
– If no cable needs to be routed through the installation position reserved, you can
replace the common sealing module with the filler module.
– Never miss any module or install the wrong module.
– Use the remaining filler modules for pre-pressing the module.
III. Installation Procedure
Caution:
z Waterproof components take effect 24 hours later after they are installed. Install
waterproof components in fine days to avoid water penetration.
z Remove the rear door of the cabinet before installing waterproof components.
To install waterproof components, proceed as follows:
1) Work out positions for cables according to the installation rule, and select modules
for cables to be installed.
2) Unpack the module, rip off the outer plastic film, and remove the filling as shown in
Figure 5-25.
Figure 5-25 Removing the filling
3) Remove core layers.
A maximum of two to three cables can be routed through a medium or small

pairs neatly.
Installation Manual – BTS3606A Cabinet Installation
Airbridge BTS3606&3606A CDMA Base Station Chapter 5 Installing Cables
Huawei Technologies Proprietary
5-33
z Avoid turning while laying optical fibers. Route optical fibers as straight as possible.
Lead optical fibers between cabinets through cabling racks, or through the top of
cabinets if convenient.
z Put the redundant optical fibers in the fiber tray. Do not cross fibers.
z Lay optical fibers naturally. Do not pull or bind them by force. Bind fibers on the
beam every 150 mm (6 in.).
z Labels at both ends of optical fibers must be clear. They must indicate the
relationship between the RF module and the fiber port on the BRDM of the
baseband subrack.
z Use corrugated plastic tubes to protect fibers when leading them out of the cabling
rack.
5.5.2 Installing Optical Fibers Cascading the ODU3601C
When the ODU3601C is cascaded with the BTS3606A, you need to connect two ends
of the optical fiber respectively to the optical interface of the CCPM on the BTS3606A
and the optical interface of the MTRM on the ODU3601C.

Figure 5-37 Wrong and correct operations
Caution:
If the cable is not long enough, replace a new one. It is not allowed to add connectors or
welding joints to the cable.
z Measure the accurate distance from the AC power distribution box to the
connecting terminal of the cabinet, and the distance from the PGND cable to the
grounding bar inside the cabinet before laying cables. Make sure to reserve
enough cables.
z Lay power cables and PGND cables apart from other cables. When paralleling
power cables to other ones, make sure that the cable distance must be more than
30 mm (0.12 in.).
z In addition, insulate power cables and PGND cables before binding them on the
metal cabling rack. Bind and bundle cables separately when routing them in the
cabinet and cabling trough, or under the tunnel.
z Lay power cables and grounding cables straight and bind them in order when
connecting them to the wiring terminal inside the cabinet. In addition, when
connecting cables to wiring terminals, lay those far form the upper wiring terminal
outside, and those near the upper wiring terminal inside.
z Reserve enough cables while laying the power cable and grounding cable inside
the cable trough. Bundle cables every 200 mm (8 in.).
z Select 150 mm (6 in.) or 300 mm (12 in.) cable ties according to the quantity of
cables. Cut the cable ties neatly.
z Use the corrugated plastic tube to protect connecting cables between the
extended battery cabinet and BTS3606A cabinet. Bundle the corrugated tube with

“Making Power Cables”. Measure the cabling route of the PGND cable to determine its
length.
5.8.2 Grounding Requirement
This section introduces the layout of the grounding system and requirement of
grounding cables and grounding resistance.
I. Layout of Grounding System
The grounding network of BTS site area must be jointly designed.
During the engineering design of BTS, the grounding system can be divided into two
independent systems: BTS system and cabling rack system. When planning the
grounding system, design these two systems separately. Connect the grounding cable
of BTS system to the grounding bar of the iron tower, and the cabling rack system to the
ground with independent grounding cables.
II. Grounding Cables
In the BTS engineering design, the customer must provide two independent grounding
cables: BTS grounding cable and cabling rack grounding cable. If the customer cannot
provide these two grounding cables, or the steel bar of the building is used for
grounding, lay these two grounding cables together, but ground them separately.
Use yellow-green cables with the cross-sectional area of 16 mm2 - 25 mm2 (19.14 ft2 -
29.9 ft2)as the grounding cables and lead them to the grounding grid.
It is required that the grounding resistance is less than five ohm for normal operation of
BTS3606A.

The resistance of the grounding body must accord with the related regulation of the
country or the operator’s regulation on communication sites (or radio base station).
5.8.3 Connecting PGND Cable of the Cabinet
To connect the PGND cable of the cabinet, proceed as follows:
1) Measure the distance between the internal ground bar of the BTS3606A and the
connector of the outdoor grounding bar according to the actual cabling path of
PGND cables.
2) Cut PGND cables as needed.
3) Attach temporary labels to both ends of each cable. Note that the contents of
temporary labels can be consistent with formal labels or defined by yourself.
4) Route the PGND cables according to cabling craft requirements and engineering
requirements.
5) Prepare PGND cables for the cabinet following the instructions in section 5.8.1
"Making Cabinet PGND Cables".
6) Lead one end of a PGND cable into the cabinet from the inlet of the waterproof
module. Connect it to the grounding bar inside the cabinet. Fasten the OT terminal
of the PGND cable using spring washers and screws.
7) Connect the other end of the PGND cable to the grounding copper bar (specified
by the customer) outside the cabinet.
8) After installing PGND cables, attach corresponding labels to the points 20 mm to
50 mm away from both ends of PGND cables according to numbers.

2) Set the multimeter to the voltage scale. Connect the negative pole of the probe to
the positive pole (in red) of the battery group, and the positive pole of the probe to
the negative (in black) of the battery group.
3) Perform different operations according different measured values as described in
Table 6-3.
Table 6-3 Measured values and corresponding operations
Measured value Operation
Measured value > 0 Indicates that the –48 V power cable and GND cable of
the battery are not connected properly. Connect them
properly and measure again.
Measured value = 0 Indicates that the cable connection is incorrect or the
battery is faulty. Connect cables correctly, clear battery
faults, and measure again.
–43.2 V < Measured
value < 0
Check whether long-term storage of the battery results
in self-discharge and low voltage. If yes, switch off the
BAT switch on the AC power distribution box and
perform the next step. If no, check whether the battery is
faulty. After the fault is cleared, measure again.
–57.6 V ñ Measured
value ñ –43.2 V
Indicates connections are correct. Switch off the BAT
switch on the AC power distribution box and perform the
next step.
4) Switch off the AC power supply and check whether the BTS3606A works normally.
5) Check the statuses of the board indicators to see whether the BTS3606A is
running properly.
If not, switch off the BAT switch. After the fault is cleared, power on the BTS3606A
again until it works normally.
6.2.4 Power-on Check of Integrated Equipment
Proceed as follows to conduct the power-on check of the integrated equipment:
1) Switch off all the power supplies on the AC power distribution box of the main
equipment.
2) Check that all the boards are inserted into slots.
3) Switch on the power supplies on the AC power distribution box sequentially and
power on the boards and modules sequentially.
4) Check whether the indicators of the boards and modules are normal.
If PWR indicator is on, the power supply is normal. If it is off, the power supply is
faulty or the indicator is damaged.

If any exception condition appears during the process, switch off the power supply
immediately. Power on again according to the above procedure after the fault is
cleared.
5) Open the rear door of the basic cabinet and check whether the voltage connecting
the AC filter is around –48 V.
If the boards and modules are normal, the preliminary check is passed.
