Replacing a Power Supply Fan

WARNING: The power supply module contains dangerous voltages which can cause electrical
shock to personnel or damage equipment.
NOTICE:
Replacing the power supply fan requires removing the power supply module. The power supply
output is directly mapped to a Power Amplifier (PA)/transceiver combination. Removal of a
power supply results in a loss of the associated channel until the replacement power supply is
inserted and turned ON.
Place a trunked device in Service Mode before replacing the module so that the system does
not attribute the loss of a channel to a failure. Placing the device in Service Mode is performed
using either the Unified Event Manager (UEM) or Configuration/Service Software (CSS).
