Intermittent problems<br />

CHAPTER 4: Troubleshooting<br />
Intermittent system hang problems can be c<strong>au</strong>sed by a variety of reasons that<br />
have nothing to do with a hardware defect. These reasons include: cosmic<br />
radiation, electrostatic discharge, or software errors. FRU replacement should be<br />
cons<strong>id</strong>ered only when a recurring problem exists.<br />
To analyze an intermittent problem:<br />
1 Run the advanced diagnostic test for the system board in loop mode at least<br />
ten <strong>tim</strong>es.<br />
• If any error is detected, replace the FRU.<br />
• If no error is detected, do not replace any FRU.<br />
2 Rerun the test to verify that there are no more errors.
