Power System
Standard AC Hot Swappable Power Supplies
The AC power system consists of two 350-watt hot-pluggable power supplies, each with
independent AC power cords 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 100V or 240V AC systems.
AC Power Supply
Power is applied to the enclosure by pressing each of the two power supply On/Off
switches to their “On” position. A Power On LED located on each power supply will be
illuminated indicating that AC power has been applied. The front bezels’ Power On LED
will also be illuminated indicating that power has been applied.
Each power supply also incorporates an amber general Fault LED. If the power supply is
installed and power is not applied to the power supply or the power supply cooling fan fails,
the Fault LED will illuminate, along with an audible alarm.
The front bezels’ Power Supply Status LED will illuminate green when both power
supplies are on and operating normally. If only one power supply is operational, the Power
Supply Status LED will be illuminated amber.
Each power supply has an AC Power Cord Module. The module has a power cord bale
incorporated into the design which secures the power cord once it has been properly
inserted, preventing inadvertent cord disconnects.
