General G idelines
When removing or replacing an FRU, ensure that you observe the following general guidelines:
1. Do not try to service any device 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.
3. Follow the correct sequence in the steps for removing an FRU, as shown in the illustrations by the
numbers in square callouts.
4. When removing an FRU, move it in the direction as shown by the arrow in the illustration.
5. To install a new FRU in place, perform the removal procedure in reverse and follow any notes that
pertain to replacement.
6. When replacing an FRU, carefully retain and reuse all screws.
7. When replacing the base cover, reapply all labels that come with the replacement base cover. f some
original labels are not included with the replacement base cover, peal them off from the original base
cover and paste them on the replacement base cover.
Attention: The system board is sensitive to and can be damaged by ESD. Before touching it, establish
personal grounding by touching a ground point with one hand or by using an ESD strap.
