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 the intermittent problem, do the following:
1. Run the advanced diagnostic test for the system
board in loop mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
