3: Controller Enclosure Operation

Turning the Power On

!
30
Use this procedure to turn on the controller enclosure power. If you are restoring power
to the controller enclosure after an emergency shutdown or power outage, go to
"Overtemp Condition and Power Supply Shutdown" on page 31.
Note: To speed drive spin-up, start the drive enclosures before or at the same time as the
controller enclosure. If you plan to use the main breaker to turn on all enclosures at the
same time, make sure the switches on each drive enclosure and each controller enclosure
are on before turning on the main breaker. For instructions on powering-up the drive
enclosures, refer to the drive enclosure documentation.
Caution: Bending or damaging Fibre Channel cables can result in degraded
performance or data loss. Fibre Channel cables are fragile and can break easily. Handle
the cables carefully when removing the rear cover of a deskside unit. Do not pinch them
with tie wraps, step on them, or bend them at sharp angles.
1. Remove the rear access panel on the rack.
Warning:
Risk of electrical shock! Never turn on the power to any equipment if
there is evidence of fire, water, or structural damage. If there is evidence of
damage, call the factory or appropriate service organization for assistance.
Depending on the current service agreements, you may or may not need to return
the unit for repair/replacement.
2. Turn on both power switches on the rear of the controller enclosure (Figure 3-2). You
must turn on both switches to take advantage of the redundant power supplies.
Then, go to "Checking the Controller Enclosure Indicator Lights" on page 36.
