Ac Power - Fujitsu IRF-1S series User Manual

Chapter 1 - Getting Started

AC Power

The 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.

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 to secure the power cord once it has been
properly inserted. The bale prevents inadvertent disconnects.
