Notes
1. For systems that are part of a shared DASD
cluster, run one test at a time in looped mode.
Do not run all tests in looped mode, as this could
enable the DASD diagnostic tests.
2. If multiple error codes are displayed, diagnose
the first error code displayed.
3. If the computer hangs with a POST error, go to
the “Symptom-to-FRU index” on page 264.
4. If the computer hangs and no error is displayed,
go to “Undetermined problems” on page 291.
5. Power Supply problems, see “Symptom-to-FRU
index” on page 264.
6. Safety information, see “Safety information” on
page 308.
7. For intermittent problems, check the error log;
see, “Error logs” on page 99.
