3. Once you know the general type of error and the general location of the
component involved, the next step is to check the system service label on the
outside top of the server.
This label gives an overview of internal components that correspond to each of
the six LEDs on the top of the server. This information, combined with the
information contained in the table “Light Path LED errors” on page 155, can
often provide enough information to correct the indicated error.
4. If necessary, you can consult the illuminated LEDs on the indicated board. For
example, a microprocessor error will light the LED next to the failing
microprocessor on one of the SMP Expansion boards.
Small computer system interface (SCSI) messages
If you receive a SCSI error message when running the SCSISelect Utility program,
see “SCSI error messages” on page 187 for more information.
If you have verified those items and the problem persists, run the diagnostic
programs to obtain additional information about the failing device. See “Starting the
diagnostic programs” on page 59.
Note: If the server does not have a hard disk drive, ignore any message that
indicates that the BIOS code is not installed.
