Strategies for replacing FRUs

Use the following strategies to prevent unnecessary expense for replacing and servicing FRUs:
• If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the
original FRU before you continue.
• Some 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 replacing one of them does not correct the problem,
reinstall that board, and then replace the other one.
• If an adapter or a device consists of more than one FRU, any of the FRUs might be the cause of the error.
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.

Strategy for replacing FRUs for GAV

General Announce Variant (GAV)
This is a standard model (fixed configuration). GAVs are announced and offered to all customers. The MTM
portion of the machine label is a 4-digit MT and 3-digit model, where model = a "fixed part number", for
example: 1829-F1U. Also, eSupport will list these products under the same fixed model number.
