General guidelines

When removing or replacing an FRU, ensure that you observe the following general guidelines:

1. Do not try to service any computer unless you have been trained and certified. An untrained person runs

the risk of damaging parts.

2. Begin by removing any FRUs that have to be removed before replacing the failing FRU. Any such FRUs

are listed at the beginning of each FRU replacement procedure. Remove them in the order in which they
are listed.
