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 either the processor board or the system board, and the first 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 symp- | |
toms | change. Replace only | the | FRU that changed |
the | symptoms. |
