8-10 Troubleshooting
The remote power-on through network does not work (Wake On LAN does not work):
Has the system been shut down forcibly?
→ After the forced shutdown (note that pressing the POWER switch on the CPU
blade also brings the power of the CPU blade to be turned off forcibly), Wake On
LAN does not work. After starting the CPU blade once, perform the normal
shutdown processing.
Is the Magic Packet sent just after the power cord is connected to the Blade Assembly
Unit?
→ After connecting the power cord to the Blade Assembly Unit and the supply of the
AC power to the CPU blade is started, wait for about 30 seconds. If the CPU blade
is started by Wake On LAN within 30 seconds, the power of the CPU blade may
not be turned on. (It corresponds to the time required to initialize the baseboard
management controller (BMC) on the CPU blade.)
Fail to power-off:
Is the POWER switch function disabled?
→ Restart the CPU blade once and then start the BIOS SETUP utility.
<Menus to check: [Security] → [Power Switch Inhibit]>
(A supervisor password must be set first).
POST fails to complete:
Is the memory installed properly?
→ POST does not operate if DIMM is not installed properly.
Are there memory devices of large capacity installed?
→ Depending on the installed memory size, it takes much time to check the memory.
Wait for a while.
Have the keyboard or mouse been used just after starting a CPU blade?
→ If you manipulate the keyboard or mouse just after the 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 compatible with the CPU blades installed?
→ NEC cannot secure the operation of any device other than those approved by
NEC.
