Shutting Down The Power; Emergency Shutdown - Hitachi HF-W2000 58 Instruction Manual

2. OPERATION

2.4 Shutting Down the Power

1. Verify that the equipment is shutdown. (See 2.3 Shutting Down the Equipment.)
2. Turn off the AC power switch on the rear side of the main unit.
3. When the AC power is off due to the operation described in step 2, the standby lamp (STBY) turns off.
4. Unplug the power cord of the equipment.

2.5 Emergency Shutdown

In the case of smoke, a burning smell, or a similar problem, unplug the power cord and contact
your dealer or maintenance personnel. Using faulty equipment without repairing it might result in
a fire or an electric shock.
● Performing an emergency shutdown (that is, unplugging the power cord or shutting off the
circuit breaker without properly shutting down the OS) might cause the OS or applications not
to work properly or might cause saved data to be corrupted. Never perform an emergency
shutdown unless some kind of error requires that you stop the system immediately.
● Note that if the power supply is cut, the system might not be able to recover automatically.
In the following cases, turn off the power at the source of the AC power:
• When the equipment exhibits an abnormal condition, and you must shutdown the power immediately (for
example, when you detect a burning smell)
• When you cannot shutdown 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 of this equipment or turn off the power at the source of the AC power:
• If the fan is stopped and the temperature becomes too high or too low, and consequently the power turns off
automatically to protect the equipment while leaving only the auxiliary power supply on.
Before the OS starts, the BIOS can detect a stopped fan during BIOS startup. If a stopped fan is detected, the
power turns off automatically.
After the OS starts, when the RAS software detects that a fan is stopped, the OS automatically shutdown and the
power turns off (this applies when RAS software is already installed).
