Chapter 9: GTR 8000 Base Radio FRU Procedures
4 NOTICE: All fan modules are delivered from the factory for dual-fan operation. If the
base radio is part of a power efficiency package configuration, the DLN6898A fan module
must be used and converted for single fan operation. Also, ensure the Tx Power Out in
the Configuration/Service Software (CSS) is limited to 50 W.
Convert for single-fan operation as follows:
a Lift the connector harness out of the rubber retainer.
b Disconnect the connector harness.
c Place each connector end into the individual pockets of the rubber retainer.
NOTICE: The DLN6898A fan module can be used in a non-power efficiency package
configuration. However, the fan module must be configured for dual-fan operation.
5 Using the guide pins and the connector on the back of the new fan assembly, push the fan
assembly into place until it feels secure.
6 Using a T20 bit, tighten the three captive screws on the front of the fan assembly. Torque to
17±2 in-lb.

use software tools, such as Unified Event Manager (UEM) or CSS to verify the status of the
equipment.

Replacing a Power Supply

WARNING: The power supply module contains dangerous voltages which can cause electrical
shock to personnel or damage equipment.
NOTICE: 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 transmit channel
until the replacement power supply is inserted and turned ON.
For a trunked device, place the channel in Service Mode before replacing the module so that the
system does not attribute the loss of channel to a failure. Placing a channel into Service Mode is
performed using either the Unified Event Manager (UEM) or the Configuration/Service Software (CSS).
