Use the following procedure as a guide for computer
problems.
Note: The diagnostic tests are intended to test only IBM
products. Non-IBM products, prototype cards, or
modified options can give false errors and invalid
system responses.
1. Obtain the symptoms in detail.
2. Verify the symptoms by running the diagnostic test to
re-create the same error or by repeating the same
operation.
Note:
To run the diagnostic test, refer to “Running
the Diagnostics” on page 34.
If the symptoms occur at irregular intervals
and cannot be re-created (and therefore
cannot be verified), go to “Symptom-to-FRU
Index” on page 23; then go to “Intermittent
Problems” on page 32.
3. Match the verified symptoms with the following table
and determine the page to go to.
