Generation 2 Single Channel Base Radio FRU Replacement Procedures

FRU Replacement Procedure

Perform the following steps to replace any of the Base Radio FRUs:

NOTE

When servicing Base Radios (BRs) in situations where

the Control Board or the entire BR is replaced, the

integrated Site Controller (iSC) will automatically

reboot the serviced BR if the BR has been off-line for a

period not less than the value contained in

“Replacement BRC Accept Timer” (default is 3

minutes). If the BR is turned on prior to that time

value, power the BR down and wait the minimum

timer length before re-powering the BR.

1. Remove power from the Base Radio by setting the Power Supply rocker

switch (located behind the front panel of the Power Supply) to the OFF (0)

position.

2. Loosen the front panel fasteners. These are located on each side of the

module being replaced.

3. Pull out the module.

4. Insert the non-defective replacement module by aligning the module side

rails with the appropriate rail guides inside the Base Radio chassis.

5. Gently push the replacement module completely into the Base Radio chassis

assembly using the module handle(s).

CAUTION

DO NOT slam or force the module into the chassis

assembly. This will damage the connectors

or backplane.

6. Secure the replacement module by tightening the front panel fasteners to the

speciﬁed torque of 5 in-lbs.

7. Apply power to the Base Radio by setting the switch to the ON position.

8. Perform the Station Veriﬁcation Procedure provided below.
