2.2 Power Supply / Fan Module

Every EP-2126-SS contains

two 300W Power Supply / Fan Modules

. All PSFMs

are inserted into the rear of the chassis.

Each PSFM delivers Full-Range (90 – 254V) AC voltage of electricity. The EP-2126-
SS normally operates with two PSFMs running. Note that each PSFM consists of 1
power supply, and 1 fan.

2.2.1 PSFM Panel

On the back 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.
