Troubleshooting 7-25

Fail to access to internal or external devices:

Are cables properly connected?

Make 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?

Operation of the server with unauthorized devices is not guaranteed. Is the power-on order correct?

When the server has any external devices connected, power on the external devices first, then the server.

Did you install drivers for connected optional devices?

Some optional devices require specific device drivers. Refer to the manual that comes with the device to install its driver.

Some optional devices connected to the serial port require settings for I/O port address and operation mode. Refer to the manual that comes with the device to configure the device.

<Menu to check: [Advanced] → [Peripheral Configuration]> Is SCSI controller (including options) configuration correct?

If the sever has an optional SCSI controller board and SCSI devices are hooked up to the server, make correct settings by the SCSI controller board’s SCSI BIOS utility. For details, see manuals included with the SCSI controller board.

Is SCSI device configuration correct?

If external SCSI devices are connected to the server, you need to make settings of SCSI ID and terminal resistance. For details, see manuals included with the SCSI device.

CPU not in Dual mode:

Check if the memory configuration is correct.

Check if third-party CPUs or memory (DIMM) are used.

Disk not in Dual mode:

Unless you perform mirroring (including reconfiguration after failed disks are replaced) in correct order, the mirror may not be [re]configured. Check if the steps were correct.
