3: Operating Storage Enclosures

To turn on the enclosure after a normal shutdown (as described in "Turning the Power Off" on
page 34), turn on both power switches on the rear of the enclosure (see Figure 3-1) or the main
circuit breaker, whichever is applicable. You must turn on both power supply switches to take
advantage of the redundant power supplies.
Note: Always wait at least 30 seconds between the time you turn a power switch off and the time
you turn it back on again.
Note: To speed drive spin-up, it is recommended that you start the expansion enclosures before
or at the same time as the controller enclosure.

Note: The activity and fault indicators above the drive bays may flash intermittently as the drives
spin up. Wait until the enclosure has finished powering on before checking the indicator lights on
the front of the enclosure. All indicators should be green. If they are not, use the storage
management software (TPSSM) to diagnose the problem.
