Checkout Guide

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.
