Chapter 5 Troubleshooting the System Hardware

Using the System Diagnostic Programs

Using the System Diagnostic Programs

The device diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the following major components of the device: the system board, Ethernet controller, RAM, serial ports, and hard disk drives. You can also use the diagnostic programs to test some external devices. See the “Diagnostic Programs and Error Messages” section on page 5-7.

If you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to 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 computer stops with a POST error, go to the “POST Error Codes” section on page 5-52.

If the computer stops and no error message is displayed, go to the “Undetermined Problems” section on page 5-25.

For power supply problems, see the “Power Supply LED Errors” section on page 5-50.

For safety information, see Chapter 2, “Preparing to Install the Wide Area Application Engine.”

For intermittent problems, check the error log.
