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.
• Verify the remote fiber connection by starting a local fiber loop-back:
- HW mode: set the local 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.
• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
NO
• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
