2.2.10 Installing the Base Station Chassis and
Modules
The indoor equipment should be installed as close as possible to the location
where the IF cable(s) enters the building. The location of the indoor equipment
should take into account its connection to the power source(s) and to the base
station networking equipment.
To install the Base Station chassis and modules:
1 Attach the Cable Guide to the top panel of the chassis using the screws and
washers supplied with the Cable Guide.
2 Install the chassis in a 19" cabinet. For installation in a 21" cabinet, attach
suitable ETSI rack adapters to the chassis. To provide a sufficient space for
the Cable Guide and to allow air flow for preventing over-heating, leave a free
space of at least 1U between the upper covers of the chassis and other units
in the cabinet.
3 Connect one end of a grounding cable to the ground terminal located on the
rear panel of the chassis and firmly tighten the grounding screw. Connect the
opposite end of the grounding cable to a ground connection or to the cabinet,
if applicable.
4 Carefully insert the modules into the relevant slots. Secure the modules in
their intended locations (refer to Section
insertion).
5 Place blank covers over all of the unused slots.
6 Connect the DATA port of the NPU to the backbone data equipment (use a
straight Ethernet cable to connect to a hub/switch/router). The maximum
length of the Ethernet cable is 100m when operating at 100 Mbps and 70m
when operating at 1 Gbps.
7 If the MGMT port will be used for remote management, connect it to the
appropriate data equipment (use a straight Ethernet cable to connect to a
hub/switch/router). The maximum length of the Ethernet cable is 100m.
8 Connect the DC power cable to the power jack of the PIU module. If a
redundant PIU is installed, connect a DC power cable also to the second PIU
module. Connect the power cord(s) to the -48 VDC power source(s), as
follows.
Connect the black wire to the 48 VDC contact of the power source.
Connect the red wire to the + (Return) contact.
