Turning On The Power; Figure 8. Turning On And Off The Power - IBM Netfinity FASt T500 User Reference

Turning on the power

Use the following procedure to turn on power to the controller unit. If you are restoring
power to the controller unit after an emergency shutdown or power outage, go to
"Overtemperature condition and power supply shutdown" on page
Important: You must turn on the drive enclosures before, or at the same time as, the
controller unit. The controllers might not recognize the correct configuration
if the attached drives are powered up after the controller unit. If you plan to
use the main breaker to turn on all enclosures at the same time, make sure
that the switches on each drive enclosure and each controller unit are on
before turning on the main breaker. For instructions on powering up the drive
enclosures, refer to the drive enclosure documentation.
Note: Always wait at least 30 seconds between the time you turn off a power switch and
the time you turn on the power again.
Turn on both power switches on the back of the controller unit (see
turn on both switches to take advantage of the redundant power supplies. Then, go to
"Checking the indicator lights" on page
