IBM Z50 manual Checkout Guide, Symptoms Verified Refer To

Checkout Guide

Use the following procedure as a guide for computer problems.

1.Obtain the failing symptoms in as much detail as possible.

2.Verify the symptoms by attempting to re-create the failure by running the diagnostic test (refer to “Running the Diagnostics Test” on page 27) or by repeating the same operation.

Note

To run the diagnostics test, refer to “Running the Diagnostics” on page 27.

If the symptoms are intermittent and cannot be re-created (and therefore not verified), go to “Symptom-to-FRU Index” on page 21 and then go to “Intermittent Problems” on page 26.

3.Use the following table with the verified symptom to determine which page to go to. Search the symptoms column, and find the description that best matches your symptom; then go to the page shown in the “Refer To” column.
