POST error messages
POST error messages can appear when a problem is detected during startup. For a
complete list of POST messages, see "POST error codes" on page 90.
Diagnostic programs and error messages
The system diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
These programs are the primary method of testing the major components of the
server.
The IBM Enhanced Diagnostics programs isolate problems from the server
hardware and software. The programs run independently of the operating system
and must be run either from a CD or diskette. If you want to run the diagnostic
programs from a diskette, you must attach an external USB diskette drive to the
server.
Diagnostic error messages indicate that a problem exists; they are not intended to
be used to identify a failing part. Troubleshooting and servicing complex problems
indicated by error messages should be performed by trained service personnel.
Sometimes the first error to occur causes additional errors. In this case, the server
displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
Error codes that might be displayed are listed at "Diagnostic error codes" on page
80.
The error code format is as follows:
fff-ttt-iii-date-cc-text message
where:
fff
ttt
iii
date
cc
text message
