Powering On The Sun Storagetek 5320 Nas Cluster Appliance, Controller Enclosures, And Expansion Enclosures - Sun Microsystems StorageTek 5320 Getting Started Manual

Powering On the Sun StorageTek 5320
NAS Cluster 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 Cluster Appliance server H1 (Server H2 will power up
during the configuration process.)
Note – If you are using a UPS, connect all units to the UPS.
Power on the expansion enclosures first, followed by controller enclosures, and then
the Sun StorageTek 5320 NAS Cluster Appliance. The redundant power supplies and
separate power cords provide fault tolerance if properly connected.
Caution – The expansion enclosures and controller enclosures must always be
powered on and properly connected to each other and the Sun StorageTek 5320 NAS
Cluster Appliance before the Sun StorageTek 5320 NAS Cluster Appliance. The
expansion enclosures must be powered on first, before the controller enclosures and
Sun StorageTek 5320 NAS Cluster 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.
