Installation
Selecting a Site for the Equipment
As with any electric device, you should place the equipment where
it will not be subjected to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you select
should meet the following requirements:
- The ambient temperature should be between 32 and 113
degrees Fahrenheit (0 to 45 degrees Celsius).
- The relative humidity should be less than 95 percent,
non-condensing.
- Surrounding electrical devices should not exceed the
electromagnetic field (RFC) standards for IEC 801-3, Level 2
(3V/M) field strength.
- Make sure that the equipment receives adequate ventilation.
Do not block the ventilation holes on each side of the
equipment or the fan exhaust port on the side or rear of the
equipment.
- The power outlet should be within 6 feet (1.8 meters) of the
equipment.

Connecting to Power
Step 1: Connect the supplied AC power cords to the receptacles on the
rear panel of the system.
Step 2: Attach the plugs from each of the dual power supplies into
standard AC outlets with a voltage range from 100~240VAC.
Step 3: Turn on the system by flipping the ON/OFF switches beside the
dual power supplies’ receptacles to the ON position.
Step 4: The power LED of each media converter will shine after turning on
the system.
Step 5: The link LED of each media converter will shine after connecting
twisted pair copper cabling between the TX port (or fiber optic
cabling between the FX port) and another working networked
device.
