2. OPERATION

2.4 Power Shutdown

Confirm that the equipment is shut down. (See "2.3 Shutting Down the Equipment".)

Unplug the optional AC adapter power cable plug from the outlet. Or unplug the

power cable directly from the DC power connector on the equipment.

In case of smoke, a burning smell, or the like, unplug the power cable from

the outlet, and contact your dealer or maintenance personnel. Using faulty

equipment without repair may result in a fire or an electric shock.

● Performing emergency shutdown (e.g. unplug the power cable from the DC

power connector without shutting down the OS, unplug the power cable of

optional AC adapter from the outlet, or turn off the circuit breaker.) 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 power at the source of power supply, the system may not be able

to recover automatically.

In the following cases, turn off the power at the source of the 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.

Also, in the following cases, either disconnect the power cable from the DC power

connector of the equipment or unplug the power cable of the optional AC adapter from the

outlet, or shut off the power at the power supply 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, after the OS starts, when a stopped fan is detected, the OS is automatically

shut down and then the power is turned off (When already RAS was installed).
