RESETTING THE CPU BLADE
This section describes how to reset the CPU blade when the CPU blade halts or when you want to
restore the factory-set BIOS configuration.
IMPORTANT: Resetting the CPU blade clears the DIMM memory
and the data in process. To reset the CPU blade when it is not frozen,
make sure that no processing is in progress.
Hardware reset
Press the RESET switch on the CPU blade. This restarts the CPU blade.
Software reset
If the CPU blade halts before starting the OS, press and hold Ctrl and Alt and press
Delete. This restarts the CPU blade.
FORCED SHUTDOWN
Use this function when an OS command does not shut down the CPU blade, the POWER switch
does not turn off the CPU blade, or resetting does not work.
Press and hold the POWER switch on the CPU blade for at least four seconds. The power is forcibly
turned off. To turn on the power back again, wait approximately 10 seconds after turning off the
power.
IMPORTANT: If the remote power-on function is used, cycle the
power once to load the OS, and turn off the power again in the normal
way.
