8-10 Troubleshooting
POST fails to complete:
‰
Is memory installed properly?
→
POST does not operate if DIMM is not installed properly.
‰
Are memory devices of large capacity installed?
→
Depending on the installed memory size, it takes much time to check the memory.
Wait for a while.
‰
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.
