9.4 Replacing a Power Supply
Figure 9-4 Power Supply
The power supply output is directly mapped to a PA/transceiver combination. Removal of a power supply
will result in a loss of the associated transmit channel until the replacement power supply is inserted
and turned ON.
It is recommended that you disable the channel before replacing the module, so that the system does not
attribute the loss of channel to a failure. You can disable a channel using Unified Event Manager, or the
Configuration/Service Software (CSS).
The Power Supply module contains dangerous voltages which can cause electrical shock to people or
damage to equipment.
