3.4 Power Shutdown
1. Confirm that the equipment is shut down. (See "3.3 Shutting Down the Equipment".)
2. Unplug the power cord from the outlet.
3.5 Emergency Shutdown
In case of smoke, a burning smell, or the like, unplug the power cord from the
outlet, and contact your supplier or maintenance personnel. Using faulty
equipment without repair may result in a fire or an electric shock.
Performing emergency shutdown (that is, unplugging the power cord from the
outlet or shutting off the breaker without proper shutdown of the OS) may
cause the OS or applications not to work properly or may cause saved data to
be corrupted. Do not perform emergency shutdown unless you must stop the
system immediately due to some kind of error.
If you turn off the power at the source of AC the power, the system may not be
able to recover automatically.
In the following cases, turn off the power at the source of the AC power.
• When the equipment shows an error condition and you have to shut down the power
immediately (for example, when a burning smell is detected).
• When you cannot shut down the equipment due to some error.
• When the power is turned off repeatedly or only the auxiliary power supply is on due to
excess current or overheating.
In the following cases, unplug the power cord from the outlet or shut down the power supply
from the power source.
• If the fan is stopped and the temperature gets too high or too low and consequently the
power is automatically turned off to protect the equipment and only the auxiliary power
supply is on. (For information about actions recommended after the power shutdown, see
After the OS starts, when a stopped fan is detected, the OS is automatically shut down and
then the power is turned off.
