General Information
The following procedures are a guide for troubleshooting computer problems. The step by step
procedures are designed to be performed as described.

cards, or modified options can give false errors and invalid system responses.
• Do not replace a non-defective FRU.
1. Obtain as much detail as possible about the problem.
2. If possible, verify the symptoms by re-creating the failure through diagnostic tests or by
repeating the operation that led to the problem.
3. Use Table 4-1 with the verified symptom(s) to determine the solution.
4. If the issue is still not resolved, see Online Support Information on page 8-2.
