Chapter 6 Troubleshooting the System Hardware
Using the System Diagnostic Programs
When you run the diagnostic programs, a single problem might cause several error
messages. When this situation occurs, you should correct the cause of the first
error message. After the cause of the first error message is corrected, the other
error messages might not occur the next time you run the test.
When troubleshooting, note the following points:
•
If multiple error codes are displayed, diagnose the first error code that is
displayed.
•
If the device stops with a POST error, go to the
“POST Error Codes” section
on page 6-49
.
•
If the device stops and no error message is displayed, go to the
“Undetermined Problems” section on page 6-21
.
•
For power supply problems, see the
“Checking the Power Subsystem” section
on page 6-11
.
•
For safety information, see
Chapter 2, “Preparing to Install the Wide Area
Application Engine.”
•
For intermittent problems, check the error log.
