2.2 Power Supply / Fan Module

Every EP-2806-SA3 contains two 300W Power Supply / Fan Modules. All

PSFMs are inserted into the rear of the chassis.

2.2.1 PSFM Panel

At the panel of the Power Supply/Fan Module, there are three distinct features: the

Power On/Off Switch, the AC Inlet Plug, and a Power On/Fail Indicator showing the

Power Status LED, indicating ready or fail.

Each fan within a PSFM is powered independently of the power supply within the

same PSFM. So if the power supply of a PSFM fails, the fan associated with that

PSFM will continue to operate and cool the enclosure.

2.2.2 Power Supply Module LED

When the power cord connected from main power source is inserted to the AC

Power Inlet, the power status LED becomes RED. When the switch of the PSFM is

turned on, the LED will turn GREEN. When the Power On/Fail LED is GREEN, the

PSFM is functioning normally.
