Server Stops or Hangs While Starting Up Typically, if the HP Server hangs before the end of POST completes, the problem is possibly a hardware problem or failure. If the HP Server hangs after POST completes, the problem is possibly due to an incorrectly configured or corrupt driver, operating system, application program, or a media (disk drive) error. If the HP Server stops working or hangs starting up: 1. Review the Troubleshooting Checklist at the beginning of the chapter before continuing. 2. Try to verify exactly where the HP Server is stopping during POST. For example: is the HP Server stopping at the memory count or on a SCSI controller? Look for any error messages and listen for any beep codes and make note of them for further assistance in troubleshooting the problem. 89
