AC power
The storage enclosure’s power system consists of two 350-watt, hot-swappable
power supplies, each with independent AC power and cooling fans. This power
system provides the enclosure with “N+1” redundant power. Each power supply
has auto-switching circuitry for use with either 110V or 220V AC systems.
To turn on the enclosure, press each of the two power supply On/Off switches
to the “on” position.
A Power LED on each power supply turns on to indicate that enclosure is turned
on. The front bezel power LED turns green when both power supplies are on
and operating normally. If only one power supply is operational, the front bezel
power LED turns orange.
The power supplies also have a general Fault LED. If the power supply is
installed and the power supply is not receiving power or if the power supply
cooling fan fails, the general power supply Fault LED turns orange and an alarm
sounds.
Each power supply has an AC power cord module. The modules have a power
cord clip incorporated into the design to secure the power cord after it has been
correctly inserted. The clip prevents accidental power cord disconnections.
