7-24 Troubleshooting

The screen turns blue during OS boot:

→Wait for the period of time you set at BIOS [Boot Monitoring]; after the boot pair is automatically swapped, the server will be rebooted and the OS will start up.

→Start the OS from the other PCI module’s hard disk.

Fail to power off the server:

Is the POWER switch enabled?

→Restart the server and start the BIOS setup utility.

<Menu to check: [Security] → [Power Switch Mask] → [Unmasked]>

POST fails to complete:

Is the DIMM installed?

→At least one DIMM is required for operation. Is the memory size large?

→The memory check may take a time if the memory size is large. Wait for a while.

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.

Does the server have appropriate memory boards or PCI card?

→Operation of the server with unauthorized devices is not guaranteed.
