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 “PWR” LED illuminated?
NO
Ensure that the power adapter is the proper type of voltage and cycle frequency
for the outlet (See “Power Supply” on page 15.)
Ensure the power adapter is properly installed in the media converter and in
the grounded outlet.
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
Proceed to step 2.
2. Is the “LKF” LED illuminated?
NO
Check the fiber cables for proper connection.
Verify that the TX and RX cables on the local media converter are connected
to the RX and TX ports, respectively, on the remote media converter.
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
Proceed to step 3.
3. Is the “Duplex/Link” LED illuminated?
NO
Check the copper cables for proper connection.
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
Amber = The media converter has selected half-duplex mode.
Green = 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 4.
4. Is the “Speed” LED illuminated?
NO
Check the copper cables for proper connection.
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
Amber = The media converter has selected 10Mb/s operation.
Green = The media converter has selected 100Mb/s operation.
If the speed is not correct, disconnect and reconnect the twisted pair cable to
restart the initialization process.
Proceed to step 5.

5. Is the “LNK” LED on a T1/E1 port (with a copper cable installed) illuminated?
NO
Check the copper cable connected to that T1/E1 port for proper connection.
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
Proceed to step 6.
6. Is the “AIS” LED on a T1/E1 port (with a copper cable installed) illuminated?
YES
The device connected to the T1/E1 port has failed. Correct the device failure.
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
NO
Proceed to step 7.
7. Is data transfer failing on the fiber port?
YES
Verify the local fiber connection by starting a remote fiber loop-back:
- HW mode: set the remote converter to fiber loop-back.
- SW mode: enter the remote fiber loop-back command.
Use a bit error test unit to run a bit error test.
