Troubleshooting:
1. Is the power LED on the media converter lit?
NO
• Refer to the previous section, “Power Supply Requirements” to verify the proper
voltage and hertz. Is the power adapter the proper type of voltage and hertz for
your AC outlet?
• Is the power adapter properly inserted into the media converter and outlet?
• Call the TE Technical Support at (800) 260-1312.
YES
• Proceed to step 2.
2. Are both the fiber Link LED and 10BaseT Link LED lit?
NO
• Check fiber and/or UTP cables for proper connection and pin assignment. Refer to
”RJ-45 Pin Specifications” in this guide to verify that the proper twisted pair cable
(straight through or crossover) is being used.
• If correct, call TE Technical Support at (800) 260-1312.
YES
• Call the TE Technical Support at (800) 260-1312.

FCC Regulations:
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own cost.

About the Media Converter:
The Transition Engineering, P/N E-TBT-FRL-FD-01, is an Ethernet Media Converter th
provides conversion from fiber optic cable (10BaseFL) to TP (twisted pair) for Full-D
Ethernet (FDE) links. The Media Converter has an RJ-45 connection and two Receive
Transmit ST type fiber optic connectors. The twisted pair side allows a device to be
located up to 100 meters (185 feet) away. The fiber optic ST connections extend the
transmission distance up to 2000 meters (6,600 feet). An SMA type fiber connection
also available, Transition Engineering P/N E-TBT-FRL-FD-01(SMA).
