Troubleshooting
Intermittent Problems
0
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 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.
Undetermined Problems
0
The diagnostic problems do not identify which adapter or device failed, which installed
devices are incorrect, whether a short circuit is suspected, or whether the system is
inoperative.
Perform the following procedures to isolate the failing FRU (do not isolate non-defective
FRU).
