1. Connecting power supply cables of a disk enclosure
Confirm the AC switches are set to off and then connect the power supply cables of the disk
enclosures. (Only for AC power supply.)
Check the power-supply cable connections of all the installed disk enclosures.
2. Connecting power supply cables of the disk array unit
Confirm the AC switches are set to off and then connect the power supply cables of the disk array
unit. (Only for AC power supply.)
The AC operating mode is enabled by default so when the power supply cables are connected
while power is being fed, the power supply is turned on. When power is not fed, connect the power
supply cables and then start feeding power.

 Avoid overloading on an electrical circuit to prevent fire.
 Do not plug in a power supply cable to an outlet and panel
board with a wet hand. Doing so may cause an electric shock.
 Do not place a heavy item on a power supply cable. Doing so
may damage the shield of the cable, which may cause a fire or
an electric shock.
Connect the power supply cables of the disk array unit after all other processes are
finished.
Use the power supply cables that come with the disk array unit.
The disk array unit and a disk enclosure have a dual-power configuration to prevent
the unit or the enclosure from being stopped when one of the power supplies fails. To
use the disk array system, connect two power supply cables individually to the disk
array unit and the disk enclosure for ensuring two lines to receive power.
Make sure to connect the cables to both the power supply PS0 and PS1.
