3: Operating Storage Enclosures
To turn on the enclosure after a normal shutdown (as described in “Turning the Power
Off” on page 32), 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.
