POST-related troubleshooting
Perform the following procedures when POST fails to run, error messages are displayed, or beep codes are
emitted.
If the POST failure is during a routine bootup, verify the following conditions:
• All external cables and power cables are firmly plugged in.
• The power outlet to which the server is connected is working.
• The server and monitor are both turned on. The bicolor power status LED indicator on the front panel must
be 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.
• All memory modules are properly installed.
If the POST failure occurs after installing an accessory, perform the following steps:
1. Perform the pre-installation procedure described on page 50.
2. If necessary, remove any expansion boards, assemblies, or cables that prevent access to the system
components.
3. Check the following conditions:
• If you have installed an expansion 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 expansion 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 procedure described on page 50.
5. Turn on the monitor.
6. If the server still does not work, repeat step 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.
