Troubleshooting
Intermittent Problems
Intermittent system hang problems can be caused by a variety of reasons that have nothing to do
with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU
replacement should be considered only when a recurring problem exists.
When analyzing an intermittent problem, perform the following:
1.
Run the advanced diagnostic test (refer to
) for the system board
in loop mode at least 10 times.
2.
If no error is detected, do not replace any FRU.
3.
If an error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
