To Power Off The Disk Array In An Emergency - HP StorageWorks XP12000 - Disk Array Owner's Manual

To power off the disk array in an emergency:

1.
Locate the UNIT EMERGENCY POWER OFF switch on the back side of the DKC. Its
location is shown in the following figure.
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.
