8-44 Troubleshooting

 Is the keyboard or mouse manipulated just after starting a CPU blade?

→ If you manipulate the keyboard or mouse just after POST is started, POST may

detect an error of the keyboard controller by mistake to halt the processing. If this

occurs, start POST again. Just after restarting POST, do not perform any operation

by using the keyboard or mouse until the BIOS start message appears.

 Are memory and PCI devices available for CPU blades installed?

→ NEC cannot secure the operation of any device other than those approved by

NEC.

"System Configuration Data Read Error" appears and POST pauses:

 Did you perform any of the following operation?

– Pressed the POWER switch of the CPU blade to forcedly power off the CPU

blade.

– Pressed the RESET switch of the CPU blade to provide hardware reset.

– Removed the CPU blade from the Blade Enclosure.

– Disconnected the power cord from the Blade Enclosure.

→ Contact your service representative.

The MAC address of the onboard LAN of the CPU blade is unknown:

→ You can find the MAC address by the label put near the MP connector on the CPU

blade. In addition, you can see the address from Windows or Linux command. See

Chapter 3 for details.

Fail to access to internal or external devices (or such devices fail to operate):

 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 the power-on order correct?

→ When the CPU blade has any external devices connected, power on the external

devices first, then the CPU blade.

 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.
