If you are instructed to replace either theprocessor board or the system board, and replacing oneof them does not correct the problem, reinstall thatboard, and then replace the other one.v If an adapter or device consists of more than one FRU,any of the FRUs may be the cause of the error. Beforereplacing the adapter or device, remove the FRUs, oneby one, to see if the symptoms change. Replace onlythe FRU that changed the symptoms.Attention: The setup configuration on the computer youare servicing may have been customized. RunningAutomatic Configuration may alter the settings. Note thecurrent configuration settings (using the View Configurationoption); then, when service has been completed, verify thatthose settings remain in effect.© Copyright IBM Corp. 2004 3
