1. Overview
The IEEE802.3u Ethernet supports two types of media for network connection: 10/100base-TX and 100base-FX. The bridge media converter is designed with a switch controller and buffer memory to smoothly connect these two types of segments. This converter can be used as a standalone unit or as a slide-in module into a 483mm (19") converter rack Chassis for use in a central wiring closet.
2. Check List
Before 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 are 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 be supplied only from the same source. Both are built to match in 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 the +5V DC power jack on the converter's back, carefully slide it in, and plug it into the 483mm (19") rack's +5V DC power receptacle.
- Connect the media cable for network connection.
- Turn on the converter rack power; the Power LED will light up.
Wire Connection
Fiber Port
Attach the fiber cable. The TX and RX fiber cables must be paired at both ends. Default: Full duplex mode.
TP Port
Attach TP Cat. 5 cable to the 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:
- 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.
- NO
- 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.
- NO
- 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.
- NO
- 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.
- NO
Note: Connecting to a Router, Bridge, or Switch, please refer to the device's Technical Manual.
