Powering down the disk array

Emergency power-off

Caution
XP1024 hardware
Situations may arise in the operation of the disk array that require the user
to power down the disk array. These situations include:
• Emergency power-off
• Planned power-off
An emergency is a critical situation such as a physical plant catastrophe. In
an emergency, the critical need is to quickly remove power from the disk
array. A quick restart is not necessary.
In an emergency, you should trip the Emergency Power-Off (EPO) switch,
which is located on the control panel.
Use this switch only in case of an emergency. An HP service representative
is required to reset the EPO and to power-on the disk array.
To power off the disk array in an emergency:
1. Open the control panel cover by pushing on the point marked PUSH .
2. Pull the emergency power-off switch
out towards you as illustrated on the switch.
3. Call the HP support center. The EPO switch must be reset by an HP
service representative before the disk array can be powered on again.
