Troubleshooting 6-11
Fail to power off the server:
θ Is the POWER switch enabled?
→ Restart the server and start the BIOS setup utility.
<Menu to check: [Security] - [Power Switch Inhibit]>
θ Is the server running in the Secure Mode?
→ The POWER switch is disabled in the Secure Mode. (Forced shutdown is also not
available.) To release the Secure Mode, enter the password specified with the
BIOS setup utility.
POST fails to complete:
θ Are the DIMMs installed?
→ At least two DIMMs are required for operation.
θ Is the memory size large?
→ The memory check may take a few seconds if the memory size is large.
θ Did you perform any keyboard or mouse operation immediately after you started the
server?
→ If you perform any keyboard or mouse operation immediately after start-up,
POST may accidentally detect a keyboard controller error and stops proceeding.
In such a case, restart the server once again. Do not perform any keyboard or
mouse operation until the BIOS start-up message appears when you restart the
server.
θ Does the server contain authorized memory boards or PCI devices?
→ Operation of the server with unauthorized components could cause system errors.
