OPERATION
After installation, the media converter should function without operator
intervention.
Status LEDs
Use the status LEDs to monitor media converter operation in the network.
Power Illuminated green LED indicates
connection to external AC power.
SDF Signal Detect/Fiber: Steady green LED
indicates fiber port is connected to
device.
SDC Signal Detect/Copper:
Steady green LED
indicates RJ-45 port is
connected to device.
RXC Receive/Copper: Flashing green LED indicates packets are seen
on RJ-45 port.
RXF Receive/Fiber: Flashing green LED indicates packets are seen
on fiber port.
Link Pass Through/Remote Fault Detect
When the Link Pass Through function is active, a fault on one side of the
media coverter stops signal and data transmission on the other side.
Original Fault
100BASE-TX
Device
When the Remote Fault Detect function is active, a fault on one side of the
media coverter allows signal, but not data, transmission on the other side.

FAULT ISOLATION and CORRECTION
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 AC outlet?
NOTE: Refer to the "Power Supply Requirements" on page 7.
• Is the power adapter properly installed in the media converter and
in the outlet?
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 2.
2. Is the SDC (Signal Detect/Copper) LED illuminated?
NO
• Check UTP cables for proper connection.
• Verify MDI/MDI-X switch position.
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 3.
3. Is the SDF (Signal Detect/Fiber) LED illuminated?
NO
• Check fiber cables for proper connection.
• Verify that TX and RX cables on media converter are connected to
RX and TX ports, respectively, on the other 100BASE-FX device.
• Refer to Tech Tips available at: http://www.transition.com
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
