10/100Base-TX to 100Base-FX
Media Converter
User’s Manual
1. Overview
IEEE802.3u Ethernet supports two types media for network connection
such as 10/100Base-TX and 100Base-FX. The bridge media converter
is designed with a switch controller and buffer memory that connects
two types segments operation smoothly. This converter can be used as
standalone unit or as slide-in module to the 483mm (19”) converter rack
Chassis for use at a central wiring closet.
2. Check List
Before you start installing the Converter, verify that the package
contains the following:

- The TP-Fiber Converter
- AC-DC Power Adapter (for external models) or Power Cord
(for internal models)
- The User’s Manual
Please notify your local sales distributor immediately if any of
the mentioned items is missing or damaged.

4. Installing the Converter
Standalone unit:
→Verify the AC-DC adapter conforms to your country AC power
requirement and insert the power plug
→Connect the media cable for network connection
Slide-in unit:
→The slide-in Media Converter and Converter Rack Chassis should
supplied only from the same source, both Media Converter Rack
Chassis are built to match each other at dimension, DC jack, DC
receptacle and power safety.
→Turn off the 483mm (19”) converter rack power
→Ensure that there is no activity in the network
→Locate +5V DC power jack on converter back, carefully slide in
and plug to 483mm (19”) rack +5V DC power receptacle
→Connect the media cable for network connection
→Turn on the converter rack power, the Power LED will light up
Fiber Port Attach the fiber cable, the TX, RX fiber cable must be paired at both ends.
Default: Full duplex mode
TP Port Attach TP Cat.5 cable to TP Port

7. Troubleshooting
If the media converter fails, isolate and correct the failure by determining
the answers to the following questions and then taking the indicated
action:
1. Is the power LED on the media converter illuminated?
NO
Is the power adapter the proper type of voltage and cycle frequency
for the AC outlet?
Is the power adapter properly installed in the media converter and in
the outlet?
Contact your local sales distributor for technical Support.
YES
Proceed to step 2.
2. Is the “Duplex/Link” LED illuminated on a port with twisted-pair
cable installed?
NO
Check the copper cables for proper connection.
YES
OFF = The media converter has selected half-duplex mode.
ON = The media converter has selected full-duplex mode.
If the mode is not correct, disconnect and reconnect the twisted pair
cable to restart the initialization process.
Proceed to step 3.

3. Is the ”Link action” LED illuminated on the fiber cable port?
NO
Check the fiber cables for proper connection.
Verify that the TX and RX cables are connected to the RX and TX
ports, respectively, on the 100Base-FX device.
YES
Proceed to step 4.
4. Is the “Speed” LED illuminated on a port with twisted-pair cable
installed?
NO
Check the copper cables for proper connection.
YES
OFF = The media converter has selected 10Mbps operation.
ON = The media converter has selected 100Mbps operation.
If the speed is not correct, disconnect and reconnect the twisted pair
cable to restart the initialization process.
Note: Connecting to Router, Bridge or Switch, please refer to the
device’s Technical Manual.
