This section describes how to power on and power off the nodes and arrays.

Powering on VLS9000 Arrays

The order in which you power up the disk array enclosures in an array is important. Be sure to power
on the base disk array enclosure last in order to ensure that the disks in the expansion disk array
enclosures have enough time to spin completely before being scanned by the RAID controllers in the
base disk array enclosure.
CAUTION:
Only power on one array enclosure at a time to avoid overloading the AC power source.
To power on an array:
1. Turn both power switches on the rear of each array enclosure on.
Always power on expansion disk arrays first, starting with the expansion disk array furthest from
the base disk array enclosure (expansion disk array enclosure 2) and working towards the base
disk array. Then power on the base disk array. See
array enclosure 2.
