About the DuraStor Storage Subsystem
Power System
The DuraStor RAID appliance power system consists of two
hot-swappable, power supply units (PSUs) and two AC power
cord connectors. This system provides the appliance with an N+1
redundant power system. Each PSU has auto-switching circuitry
for 110/220 VAC systems.
The DuraStor RAID appliance PSU is shown in

You access the PSUs by removing the front bezel, and turn them on
by using their On/Off switches. When you turn on a PSU, its own
Power-on LED and the Power LED on the front bezel light up, and
the DuraStor RAID appliance performs a power-on self-test
(POST), which can be monitored via the LCD panel on the OCP.
