POST beep codes

POST generates beep codes to indicate successful completion or the detection of a problem.

vOne beep indicates the successful completion of POST.

vMore than one beep indicates that POST detected a problem. For more information, see “Beep symptoms” on page 97

POST error messages

POST error messages occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration. For a list of POST errors, see “POST error codes” on page 110

Event/error logs

The POST error log contains the three most recent error codes and messages that the system generated during POST. The System Event/Error Log contains all error messages issued during POST and all system status messages from the Advanced System Management Processor.

To view the contents of the error logs, start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility program” on page 33); then, select Event/Error Logs from the main menu.

Small computer system interface messages

If you receive a SCSI error message, see “SCSI error codes” on page 118

Note: If the server does not have a hard disk drive, ignore any message that indicates that the BIOS is not installed.

You will get these messages only when running the SCSI Select Utility.
