Power Supplies

Redundant, hot-swappable 450-watt power supplies convert wide-ranging AC voltage from an
external main to stable DC output and deliver it to the backplane. Each power supply has two
internal blowers, an AC receptacle (A in
an LED (C). Internal control prevents the rear DC connector from becoming energized when
the power supply is removed from the disk enclosure.

as soon as possible.
