Chapter 4: Troubleshooting
Intermittent problems
Intermittent system hang problems can be caused by a variety of reasons that have nothing to do
with a hardware defect. These reasons include: cosmic radiation, electrostatic discharge, or
software errors. FRU replacement should be considered only when a recurring problem exists.
To analyze an intermittent problem:
1
Run the advanced diagnostic test for the system board in loop mode at least ten
times.
❑
If any error is detected, replace the FRU.
❑
If no error is detected, do not replace any FRU.
2
Rerun the test to verify that there are no more errors.
