5 Diagnostics This section provides basic troubleshooting information to help you solve some common problems that might occur with your blade server. If you cannot locate and correct the problem using the information in this section, see Appendix A, "Getting help and technical assistance," on page 93 for more information. General checkout The server diagnostic programs are stored in the upgradeable read-only memory (ROM). These programs test the major components of your blade server. 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. Notes: 1. If multiple error codes are displayed, diagnose the first error code that is displayed. 2. If the server stops with a POST error, go to "POST error codes" on page 76. 3. If the blade server stops and no error is displayed, go to "Undetermined problems" on page 100. 4. For safety information, see "Electrical Safety" on page vi. 5. For intermittent problems, check the error log. 6. If blade front panel shows no LEDs, verify blade status and errors in SBCE web interface; also see "Undetermined problems" on page 100. 7.

The server diagnostic programs are stored in the upgradeable read-only memory (ROM).
These
programs test the major components of your blade server.
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.
Notes:
1.
If multiple error codes are displayed, diagnose the first error code that is displayed.
2.
If the server stops with a POST error, go to “POST error codes” on page 76.
3.
If the blade server stops and no error is displayed, go to “Undetermined problems” on page 100.
