Intermittent Problems (TP 560Z - 2640)
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:
- 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 FRUs.
- If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more errors exist.
