FRU Replacement Strategy

Before Replacing Parts

Ensure that all diskette fixes are installed prior to replacing any FRUs listed in this manual.

Use the following strategy to prevent unnecessary FRU replacement and service expense:

Ÿ

If

you

are instructed

to replace a FRU

and

that

 

does

not

correct the

problem, reinstall

the

original

 

FRU

before

you continue

.

 

 

ŸSome computers have both a processor board and a system board. If you are instructed to replace eith

the processor board or the system board, and the fi board that you replaced does not correct the problem reinstall the original board, then replace the other (processor or system) board.

ŸIf an adapter or device consists of more than one FRU, an error code may be caused by any of the FRUs. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that

changed the symptoms.

Warning: A customized setup configuration (other than default settings) may exist on the computer you are servicing. Running Automatic Configuration may alter those settings. Note the current configuration settings (using the View Configuration option) and verify that the settings are in place when service is complete.
