Step Operation
0 Check the disk array controller and the disk enclosures are connected correctly.
When AC power supplies are installed, check AC switches of the disk array controller
and disk enclosures are set to off.
1 When AC power supplies are installed, set the AC switches to on, in the order of the
disk enclosure and the disk array controller.
2 Step 2 should be performed only when AC operating mode is disabled.
Press the DC button of a controller (CONT), which is located at the rear of the disk array
controller, for approximately one second until fans start to rotate. The disk array
controller will be powered on. The disk enclosures will be powered on sequentially as
the disk array controller is powered on.
Proceed to step 3.

When AC operating mode is enabled (factory default settings), the disk array
system with AC power supplies is automatically powered on at the time the
disk array controller is powered on while the disk array system with DC power
supplies is automatically powered on at the time the power supply input cable
is connected to the disk array controller or the disk array unit is powered on.
Disk enclosures are sequentially powered on in association with the disk
array controller. Proceed to step 3.
If AC operating mode is disabled, proceed to step 2, otherwise proceed to
step 3.
