Troubleshooting 7-11
POST fails to complete:
†
Is the DIMM properly installed?
→
At least one pair of DIMM(2 DIMMs) is required for operation.
†
Is the memory size large?
→
The memory check may take a time if the mounted memory size is large. Wait for
a while.
†
Did you perform any keyboard or mouse operation immediately after you started the
server?
→
If 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?
→
Operation of the server with unauthorized devices is not guaranteed.
†
Are the System BIOS and Emulex BIOS of the server configured?
→
The parameter differs from the factory default. Make settings by the System BIOS
setup Utility and Emulex BIOS configuration Utility. For details, see Chapter4 of
User's Guide (Setup).
Server reboots while running the SAS Configuration utility:
†
Have you modified the Setup settings?
→
From [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 SAS Configuration utility. Change back the
setting after you finish using the utility.
Fail to access to 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, and 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. Make correct settings by the System
BIOS setup Utility and Emulex BIOS configuration Utility. For details, see
Chapter4 of User's Guide (Setup).
