Light path diagnostics table
The System Error LED on the operator information panel is lit when certain system
errors occur. If the System Error LED on your server is lit, use the table in
“Information panel system error LED” on page 128 to help determine the cause of
the error and the action you should take.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradable 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.
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 running the diagnostic programs.
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.
