Installation
As with any electric device, you should place the equipment where it will not
be subject to extreme temperatures, humidity, or electromagnetic interference.
Specifically, the site you select should meet the following requirements:
Please follow the steps to install the media converter. This Converter is a
plug-and-play device.
1. Turn off the power of the device/station in the network in which the media
converter will be installed.
2. Ensure that there is no activity in the network.
3. Attach fiber cable from the media converter to the fiber network. The fiber
connections must be Matched-Transmit socket to receive socket
4. Attach a UTP cable from the 100Base-Tx network to the RJ-45 port on the
product
5. Connect the power cord to the media converter and check if the power
LED lights up. The TP Link and FX link LED will light when all the cable
connections are satisfactory.
6. Turn on the power of the device/station.
