7.2Power On/Off of Additional Disk Enclosure

This section describes how to turn on or off the power of the additional disk enclosure. Turning on or off the power carelessly may cause some data to be broken, some software to operate incorrectly, and/or the device to be defected.

(1)AC power-on

a)Before turning on the AC power, check for loose disk drives by pushing each disk drive.

b)Turn on all the disk enclosures connected with the array controller, and then turn on the array controller. Alternatively, turn on the array controller and all the 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 on the disk enclosure, turn on all the power switches (of the array controller and disk enclosures) at the rear of the unit.

When turning on the power switches, confirm that the POWER GOOD LED (green) of the power supply and the POWER LED (green) on the front panel of the unit go on. Power supply starts, and the POWER LED (green) is on while the power switches are on.

The additional disk enclosure performs the self-test and initialization immediately after the power is turned on. When the self-test and initialization terminate and the disk enclosure becomes ready, the READY LED of the adapter stops flashing and enters the on state. The READY LED of the controller installed on the disk array unit also stops flashing and enters the on state.

The additional disk enclosure (including the connected disk array unit) takes four minutes (at maximum) to start.
