Strategy for replacing parts (FRU-Field Replaceable Units)

Before replacing parts
Make sure that latest BIOS and drivers are installed before replacing any parts (FRUs) listed in this

Use the following strategy to prevent unnecessary expense for replacing and servicing parts
1. If you are instructed to replacing a part but the replacement does not correct the problem, reinstall the
original part before you continue.
2. Some computers have both a processor board and system board. If you are instructed to replace either
the processor board or the system board, and replacing one of them does not correct the problem,
reinstall that board, and then replace the other one.
3. If an adapter or device consists of more than one part, any of the parts (FRUs) may be the cause of the
error. Before replacing the adapter or device, remove the parts (FRUs), one by one, to see if the
symptoms change. Replace only the part that changed the symptoms
