About the checkout procedure
Use this information to run diagnostics, locate error codes, and identify device errors for the blade server.
Before you perform the checkout procedure for diagnosing hardware problems, review the following
information:
• Read “Safety” on page iii and “Installation guidelines” on page 37.
• The diagnostic programs provide the primary methods of testing the major components of the blade
server. If you are not sure whether a problem is caused by the hardware or by the software, you can use
the diagnostic programs to confirm that the hardware is working correctly.
• When you run the diagnostic programs, a single problem might cause more than one error message.
When this happens, correct the cause of the first error message. The other error messages usually will not
occur the next time you run the diagnostic programs.
• If the blade server is halted and a POST error code is displayed, see “POST/UEFI diagnostic codes” on
page 81. If the blade server is halted and no error message is displayed, see “Troubleshooting tables” on
page 188 and “Solving undetermined problems” on page 262.
• For intermittent problems, check the error log; see “Event logs” on page 79 and “IBM Dynamic System
Analysis Preboot diagnostic program” on page 209.
