7-24 Troubleshooting

Fail to power off the server:

†Is the POWER switch enabled?

οRestart the server and start the BIOS setup utility.

<Menu to check: [Security] ο [Switch Inhibit] ο [Enabled]>

†Are you trying to power off by a method other than pressing the POWER switch?

οYou cannot power off the server by using software commands such as the shutdown command. Press the POWER switch to power off the server.

POST fails to complete:

†Is the DIMM installed?

οAt least one DIMM is required for operation.

†Is the memory size large?

οThe 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?

οIf 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?

οOperation of the server with unauthorized devices is not guaranteed.

Server reboots while running the SCSISelect utility:

†Have you modified the Setup settings?

οFrom [Server] - [Monitoring Configuration] - [Option ROM Scan Monitoring] of

Setup, select “Disabled.” If [Option ROM Scan Monitoring] is enabled, the system may reboot while using the SCSISelect utility. Change back the setting after you finish using the utility.

Fail to access to internal or external devices:

†Are cables properly connected?

οMake sure that the interface cables and power cord are properly connected. Also make sure that the cables are connected in the correct order.

†Is that device compliant with NEC Express5800/ft series?

οOperation of the server with unauthorized devices is not guaranteed.
