4.3 Powering On/Off the Disk Array Unit
This section describes how to turn on or off the power of the disk array unit. Turning on or off the
power carelessly may cause some data to be corrupted, some software to operate incorrectly, and/or
the unit to become defective.
Turning on AC power
a) Before turning on the power, push each hard disk drive to make sure they are all fully
inserted.
b) Turn on both power switches on the rear of the disk array unit.
If an additional disk enclosure is connected, first turn on the two power switches on the rear
of the additional disk enclosure, and then turn on the two power switches on the rear of the
disk array unit. Alternatively, turn on the disk array unit and all the additional disk enclosures
connected with the disk array unit at the same time.
The disk array unit and additional disk enclosure have a redundant power configuration to
prevent the entire unit from shutting down due to a single failure. Therefore, when turning on
the disk array unit, turn on all the power switches (of the disk array unit and additional 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 disk array unit and the
additional disk enclosure(s) light on. Power supply starts, and the POWER LED (green) is on
while the power switches are on.
The disk array unit performs the self-test and initialization sequence immediately after the
power is turned on. When the self-test and initialization terminate and the disk array unit
becomes ready, the DIR LED of the controller on the disk array unit stops lighting and starts
flashing. Confirm the DIR LED status, and then turn on the host system.
The disk array unit takes 15 minutes (at maximum) to start.
