7-28 Troubleshooting
Fail to power-off:
‰ Is the POWER switch function disabled?
→ Restart the modular server and then run the BIOS SETUP utility.
The modular server unexpectedly turned off or shutdown:
‰ Is any temperature alarm or warning detected?
→ The modular server shuts down when temperature alarm or warning is detected.
Use the modular server in an appropriate operating environment.
POST fails to complete:
‰ Is DIMM installed properly?
→ POST does not operate if DIMM is not installed properly.
‰ Is the keyboard or mouse manipulated just after starting a modular server?
→ 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, run POST again. Just after restarting POST, do not perform any operation
by using the keyboard or mouse until the BIOS start message appears.
‰ Are DIMMs available for modular servers 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/SLEEP switch of the modular server to forcedly power
off the modular server.
– Removed the modular server from the Module Enclosure.
→ Contact your service representative.
The MAC address of the onboard LAN of the modular server is unknown:
→ You can find the MAC address by the label put near the edge of the modular
server. See Chapter 3 for details.
