Unknown problem
Action
:
1.
Power down and disconnect power to the server.
2.
Following the guidelines and cautionary information in the server documentation, reduce the server to
the minimum hardware configuration by removing all cards or devices that are not necessary to start the
server. Keep the monitor connected to view the server startup process. Before completing this step, see
"Breaking the server down to the minimum hardware configuration (on page
17
)."
3.
Reconnect power, and then power on the system.
o
If the video does not work, see "Video problems (on page
54
)."
CAUTION:
Only authorized technicians trained by HP should attempt to remove the system
board. If you believe the system board requires replacement, contact HP Technical Support
("
Contacting HP
" on page
177
) before proceeding.
CAUTION:
Before removing or replacing any processors, be sure to follow the guidelines
provided in "Performing processor procedures in the troubleshooting process (on page
17
)."
Failure to follow the recommended guidelines can cause damage to the system board, requiring
replacement of the system board.
o
If the system fails in this minimum configuration, one of the primary components has failed. If you
have already verified that the processor, PPM, power supply, and memory are working before
getting to this point, replace the system board. If not, be sure each of those components is working.
o
If the system boots and video is working, add each component back to the server one at a time,
restarting the server after each component is added to determine if that component is the cause of
the problem. When adding each component back to the server, be sure to disconnect power to the
server and follow the guidelines and cautionary information in the server documentation.
Third-party device problems
Action
:
1.
Refer to the server and operating system documentation to be sure the server and operating system
support the device.
2.
Be sure the latest device drivers are installed.
3.
Refer to the device documentation to be sure the device is properly installed. For example, a third-party
PCI or PCI-X board may be required to be installed on the primary PCI or PCI-X bus, respectively.
Testing the device
Action
:
1.
Uninstall the device.
If the server works with the device removed and uninstalled, a problem exists with the device, the server
does not support the device, or a conflict exists with another device.
