2.6.5 Installing the BS-SH Chassis and Modules
This section describes how to install the power supply and Access Unit network
interface modules in the Base Station chassis.
To install the BS SH chassis and modules:
1 Install the BS-SH chassis in a 19” cabinet. To prevent over-heating, leave a
free space of at least 1U between the upper/lower covers of the BS-SH chassis
and other units in the cabinet.
OR
Place the BS-SH chassis on an appropriate shelf or table. When mounting the
BS-SH on a shelf or table, attach the rubber legs supplied with the unit.
2 Connect one end of a grounding cable to the ground terminal located on the
rear panel of the BS-SH chassis and firmly tighten the grounding screw.
3 Connect the opposite end of the grounding cable to a ground connection or to
the cabinet, if applicable.
4 Carefully insert the BS-PS power supply and the BS-AU modules into the
relevant slots and push firmly until they are securely locked. Before insertion,
verify that the switches of all BS-PS modules are in the OFF position. Refer to
section 2.6.1
for a description of the slot assignment.
5 Close the captive screws attached to each module.
6 Place blank covers over all of the unused slots.
7 Connect the indoor-to outdoor cable(s) to the RADIO connector(s) of the
BS-AU module(s).
8 If a BS-PS-DC power supply is used, connect the DC power cord to the -48
VDC IN jack of the BS-PS-DC power supply. If a redundant power supply
module is installed, connect a DC power cord also to the second DC power
module. Connect the power cord(s) to the -48 VDC power source, as follows:
a Connect the black wire to the 48 VDC contact of the power source.
b Connect the white wire to the + (Return) contact.
c Connect the shield to the ground.
9 If a BS-PS-AC power supply is used, connect the AC power cord to the AC IN
jack of the BS-PS-AC power supply. If a redundant power supply module is
installed, connect an AC power cord also to the second AC power module.
Connect the power cord(s) to the mains outlet.
10 Switch the BS-PS-AC/DC power supplies to ON. Verify that all power
indicator LEDs on the BS-PS-AC/DC front panel are ON and that the
