4.
Is the copper Duplex/Link LED illuminated yellow or green?
NO
•
Check the twisted pair cables for proper connection.
•
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES - Yellow
•
The media converter has selected half-duplex mode for the twisted pair
link. If this is not the correct mode, disconnect and reconnect the
twisted pair cable to restart the initialization process.
•
Proceed to step 5.
YES - Green
•
The media converter has selected full-duplex mode for the twisted pair
link. If this is not the correct mode, disconnect and reconnect the
twisted pair cable to restart the initialization process.
•
Proceed to step 5.
5.
Is the copper Speed LED illuminated?
NO
•
The media converter has selected 10 Mb/s operation. If this is not the
correct speed, disconnect and reconnect the twisted pair cable to restart
the initialization process.
•
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES - Flashing Yellow
•
The media converter has selected 100 Mb/s speed. If this is not the
correct speed, disconnect and reconnect the twisted pair cable to restart
the initialization process.
•
Proceed to step 6.
YES - Flashing Green
•
The media converter has selected 1000 Mb/s operation. If this is not the
correct speed, disconnect and reconnect the twisted pair cable to restart
the initialization process.
•
Proceed to step 6.

Is data transfer failing?
(Loop-back test scenario #1)
YES
•
Verify the local fiber connection by starting a remote fiber loop-back
(enter the remote fiber loop-back command in software mode)
and then use a
bit error test unit to run a bit error test.
OAM mode: The signal received on the remote connector’s RX fiber
interface is looped back over the TX fiber cable. In this scenario, the
loop-back data is not transmitted over the copper cable.
NO
•
Proceed to step 7.
7.
Is data transfer failing?
(Loop-back test scenario #2)
YES
•
Verify the local fiber connection by starting a remote fiber loop-back
(enter the remote fiber loop-back command in software mode
) and then use a
bit error test unit to run a bit error test.
Set the test equipment’s destination address to FF:FF:FF:FF:FF:FF
(broadcast)
. The signal received on the remote connector’s RX fiber
interface is looped back over the TX fiber cable. In this scenario, the
loop-back data is transmitted over the copper cable.
