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 84.
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
76.
The error code format is as follows:
fff-ttt-iii-date-cc-text message
where:
fff is the three-digit function code that indicates the function being tested when
the error occurred. For example, function code 201 is for memory.
ttt is the three-digit failure code for the exact test failure. (These codes are for
trained service personnel.)
iii is the three-digit device ID. (These codes are for trained service personnel.)
date is the date that the diagnostic test was run and the error recorded.
cc are the check digits that are used to verify the validity of the information.
text message
is the diagnostic message that indicates the reason for the problem.
