2.3 Electrical Connections
After the base station/repeater equipment has been mechanically installed, electrical connections
must be made. This involves making the following connections to:
• power supply,
• antenna coax cables,
• system cables, and
• wireline telephone lines.
IMPORTANT: When installing option boards, ensure that an Electro-Static Discharge
(ESD) cable is connected (via banana plug) to the hole in the front-right
handle of the base station/repeater when installing option boards.
Otherwise, the option boards may be damaged. See Figure 2-9.
Figure 2-9 ESD Connect
There are also electrical connections associated with maintenance and troubleshooting of the base
station/repeater. These connectors are located on the front of the SCM (see Service Connections
section for position of these connectors).
Figure 2-10 shows the position of the base station/repeater external connectors located at the rear of
the base station/repeater.
