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, do the following:
- Run the advanced diagnostic test for the system board in loop mode at least 10 times.
- If no error is detected, do not replace any FRU.
- If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
