The System Will Not Boot
1. Ensure the NetServer is plugged into to the correct power source.
NOTE The HP NetServer LC 2000/LC2000r has a 15 second delay after power is initially
applied and will not respond to the front panel controls during this time period while it
performs self-test.
2. Inspect the system board and verify all DIMMs are installed.
3. Verify the DIMMs are fully seated. When the DIMMs are fully seated, the retaining latches are
closed.
4. Verify the DIMM configuration on the system board matches those allowed. A minimum of one
DIMM must be installed.
5. Check the boot order in the Setup Utility and the SCSI Configuration Utility.
6. Verify the processor module(s) is/are installed in the correct slot(s).
7. If the system fails during boot, but without a video display, listen to the beep codes to get an
error message.
8. If the system fails during boot and presents a POST error code, use the
à POST error code listing, or the
à Event Log Display
to decode the error and get suggested remedies.
9. If the system fails during boot without a clear error message, consider attempting a BIOS
recovery.
NOTE If there is any text (video) displayed on the NetServer's monitor, using BIOS recovery
will not solve the problem.
Intermittent Failures
1. Verify the HP NetServer is plugged into to a stable 120 VAC power source.
2. Ensure the fan module is fully seated.
3. Ensure the internal SCSI Drives are connected to the correct SCSI cable (terminated or un-
terminated) and that termination is not enabled on any of the SCSI drives.
Only one of the internal SCSI cables is terminated.
4. Verify the processor module(s) is/are installed in the correct slot(s), or a terminator board is
installed in the unused slot.
5. Reseat the DIMMs on the system board.
Troubleshooting Checklist
These instructions do not generally cover third-party components or devices. Refer to the documentation that
comes with the third-party device for diagnostic and troubleshooting information. When replacing the system
board, ensure all previously installed components are removed from the original processor or system board
and are installed on the replacement board.
