8-30 Troubleshooting
RESETTING THE SERVER
If the server halts before starting the OS, press and hold Ctrl and Alt and press Delete . This restarts
the server.
IMPORTANT:
Resetting the server clears the DIMM memory and the
data in process. To reset the server when it is not frozen, make sure that
no processing is in progress.
FORCED SHUTDOWN
Use this function when an OS command does not shut down the server, the POWER/SLEEP switch
does not turn off the server, or resetting does not work.
Press and hold the POWER/SLEEP switch on the server 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 (forced shutdown).
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.
„
If the processor is heated excessively, the circuit for protecting
expensive components is started. If so, the POWER/SLEEP switch
cannot be used to control the power because the system is entered
into the reset status. Pull out the power cord and turn off the power.
After a while, check the operation environment (including the
ambient temperature). Then connect the power cord and turn on the
power. It may be necessary to leave the power-off status in the
period until the processor is cooled sufficiently (about five minutes
in normal).
Press here for at
least 4 seconds.
