Powering Off VLS9000 Arrays

CAUTION:
Always power off the system before disconnecting disk array cables or powering off a disk array
enclosure to prevent the appliance from erroneously detecting a disk array RAID volume failure.
NOTE:
It is not necessary to power off a disk array enclosure when replacing a power module, hard drive,
RAID controller, or expansion controller.
To power off a VLS9000 array:
1. Power off the system. See
2. Turn both power switches on the rear of each disk array enclosure off.
Always power off the base disk array enclosure first. Then power off the expansion disk array
enclosures, starting with the expansion disk array enclosure at the beginning of the SAS chain
and working away from the base disk array enclosure.
