POST-related Troubleshooting
Perform the following procedures when POST fails to run or display error messages or emit
beep codes.
If the POST failure is during a routine bootup, check the following:
•
All external cables and power cables should be firmly plugged in.
•
The power outlet to which the server is connected is working.
•
The server and monitor are both turned on. The bicolor status LED indicator on the front
panel must be lit up green.
•
The monitor's contrast and brightness settings are correct.
•
All internal cables are properly connected and all boards firmly seated.
•
The processor is fully seated in its socket on the system board.
•
The heat sink is properly installed on top of the processor.
•
Verify that the all memory modules are properly installed.
If the POST failure occurs after installing an accessory, check the following:
1.
Remove the PCI riser board assembly following the procedures described on page 3-37.
2.
If necessary, remove any accessory boards or cables that prevent access to the system
components.
3.
Check the following:
•
If you have installed a PCI accessory board, verify that the board is firmly seated in
its slot and any switches or jumpers on the board are properly set.
Refer to the documentation provided with the accessory board.
•
All internal cabling and connections are in their proper order.
•
If you have changed any switches on the system board, verify that each one is
properly set.
4.
Perform the post-installation procedures described on page 3-6.
5.
Turn on the monitor.
6.
If the server still does not work, repeat steps 1 and 2.
7.
Remove all accessories, except the primary boot hard disk drive.
8.
Repeat steps 4 and 5.
If the server now works, replace the boards and accessories one at a time to determine which
one is causing the problem.
