Note: If your server does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradeable read-only memory
(ROM) on the system board. These programs are the primary method of testing the
major components of your server.
Diagnostic error messages indicate that a problem exists; they are not intended to
be used to identify a failing part. Troubleshooting and servicing of complex
problems that are 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.
The following sections contain the error codes that might appear in the detailed test
log and summary log when the diagnostic programs are run.
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 089 is
for the microprocessor.
ttt is the three-digit failure code that indicates the exact test failure that
was encountered. (These codes are for trained service personnel;
see “Diagnostic error codes” on page 88).
iii is the three-digit device ID. (These codes are for trained service
personnel; see “Diagnostic error codes” on page 88).
date is the date that the diagnostic test was run and the error recorded.
cc is the check value that is used to verify the validity of the
information.
text message is the diagnostic message that indicates the reason for the problem.
Text messages
The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
is the name of the function being tested when the error occurred. This
corresponds to the function code (fff) shown in the error code format in the
previous section.
Result
can be one of the following:
Passed This result occurs when the diagnostic test
is completed without any errors.
