XP12000 Operations
To power off the disk array in an emergency:
1. Locate the UNIT EMERGENCY POWER OFF switch on the back side
of the DKC.
Rear view of DKC
Figure 5. Unit emergency power off switch
2. Pull the switch up and then out towards you.
The disk array shuts down immediately. The UNIT EMERGENCY
POWER OFF switch mechanically locks itself in the off position to
prevent anyone from restoring power in a potentially hazardous
situation.
Warning
The UNIT EMERGENCY POWER OFF switch provides only partial
power-off capability. AC input power remains present at the primary
circuit.
3. When the emergency situation is over, call the HP support center. Only
a qualified HP support representative can reset the switch and restore
power to the disk array.
