2.2 Power Supply / Fan Module
Every EP-2126-SA3 contains two 300W Power Supply / Fan Modules. All PSFMs
are inserted into the rear of the chassis.
2.2.1 PSFM Panel

15
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.
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.
2.2.3 Power Supply Installation
In this section, you will be shown how to install the Power Supply.
a. Check for damage, especially to the PCB Golden Fingers at the rear of the Power
Supply.
CAUTION! Handle the module with care and avoid damaging
the Golden Fingers. In addition, make sure there are no
fingerprints on the Golden Fingers. Do not install the module if
the Golden Fingers are damaged.

16
b. With the Power Supply handle in the open position, carefully insert the module into
the enclosure.
CAUTION! When inserting the PSFM, make sure the PSFM
position is correct (the handle is in the lower part when
closed).
c. Manually close the Power Supply handle.
IMPORTANT! To secure the Power Supply to the enclosure,
tighten the thumb screws.
d. Connect the Power Supply cord from the power source to the AC Power Inlet.
IMPORTANT! For safety reasons, make sure the power
switches are turned off when you plug-in the power
cords. When removing the power cords, ensure that the
switch on the back of each power supply fan module are
turned off and the power on/fail LED are red.

17
2.2.4 Fan Replacement
1. Remove the Power Supply Fan Module from the enclosure.
2. Unscrew 6 screws; 2 from left side, 2 from right side and 2 from top cover.
3. Pull up the top cover.
4. Disconnect the fan cable.
5. Unscrew the 4 screws of the power supply fan. Then remove the metal brace.

18
6. Remove the fan and replace.
2.3 Drive Carrier Module
The Drive Carrier Module houses a 3.5 inch hard disk drive. It is designed for maximum
airflow and incorporates a carrier locking mechanism to prevent unauthorized access to
the HDD.
2.3.1 Disk Drive Status Indicators
Every Drive Carrier has 2 status indicator lights. One indicator light is used for Power
On/Error. When this light is GREEN the power is on and everything is functioning
normally. When the Power On/Error light is ORANGE, then an error has occur that
requires the user’s attention.
The other status indicator light is the hard disk drive access light. When the hard disk
drive is being accessed, this light will flash BLUE.
In addition, both indicator lights are viewable within a 170° arc.
