(3)Turning off AC power

Turn off the powers of the additional disk enclosure and disk array unit in the following procedure.

a)Turn off the host system or FC-AL switch, and then perform the procedure explained in "(2) Notes on AC power-off".

b)After finishing the operation in a, turn off the array controller and then all the disk enclosures including additional disk enclosures. Alternatively, turn off the array controller and all the disk enclosures including additional disk enclosures connected with the array controller at the same time.

The additional disk enclosure has the redundant power configuration to prevent the entire unit from shutting down due to a single failure. Therefore, when turning off the disk array unit, turn off the two power switches at the rear of the disk enclosure.

Be careful that data may be lost if you turn off the disk enclosures before the array controller.
