Powering On When AC Power Has Not Been Turned Off

If the AC power was not turned off on turning off power supplies, power-on using the procedure
below.
(1) Press the power button on the right end of the rear surface of the disk array unit for three or
more seconds.
(Continue to press it until the DC power supply is turned on.)
(For a two-controller mode, press the power button of either controller.
You need not press both.)
(2) Wait until the RDY LED blinks at 1-second intervals. (This takes about two minutes.) The
disk array unit performs self-test and initialization. If the disk array unit is ready after
completion of the self-test and initialization, the RDY LED on each controller changes from
lighting to blinking.
(3) Confirm that the RDY LEDs start blinking and then turn on the power of the
business server.
