Powering On the Sun StorageTek 5320
NAS Appliance, Controller Enclosures,
and Expansion Enclosures
Caution – Always power on the units in the following order:
1. Sun StorEdge 5300 Expansion Enclosures
2. Sun StorEdge 5300 RAID Controller Enclosures
3. Sun StorageTek 5320 NAS Appliance
4. The redundant power supplies and separate power cords provide fault tolerance if
properly connected.
Note – If you are using a UPS, connect all units to the UPS.
Caution – The expansion enclosures and controller enclosures must always be
powered on and properly connected to each other and the main appliance before the
Sun StorageTek 5320 NAS Appliance is powered on. The expansion enclosures must
be powered on first, before the controller enclosures and Sun StorageTek 5320 NAS
Appliance. If these instructions are not followed, the system could start slowly.
Note – To achieve fault tolerance, units with two power supplies should receive
power from two different AC circuits.
Caution – When you power off the controller enclosures and expansion enclosures,
wait five seconds before you power them back on. If you power the units off and on
too quickly, unexpected results can occur.
