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, electronic discharge, or software errors. FRU replacement should only be considered when a recurring problem exists.

When analyzing an intermittent problem, do the following:

1.Run the diagnostic test for the system board at least 10 times.

2.If no error is detected, do not replace any FRUs.
