Troubleshooting
1.
Is the PWR
(power)
LED lit?
NO
• Is the power adapter the proper type of voltage and cycle frequency for the AC outlet?
• Is the power adapter properly installed in the media converter and in the outlet?
• If power LED blinking, may indicate incorrect or faulty power supply.
YES
• Proceed to step 2.
2.
Verify DIP switch settings on pages 6 and 7. RJ45 port may auto-negotiate speed and duplex
with the link partner if enabled, otherwise it is defined by the DIP switch. Fiber port speed and
duplex are DIP switch defined only.
3.
Is the Duplex LED lit Amber or green?
NO
• Check the copper cables for proper connection.
YES - Amber
• The media converter has selected half-duplex mode. If this is not the correct mode, disconnect
and reconnect the copper cable to restart the negotiation process.
• Proceed to step 4.
YES - Green
• The media converter has selected full-duplex mode. If this is not the correct mode, disconnect
and reconnect the copper cable to restart the negotiation process.
• Proceed to step 4.

Is the LACT LED lit?
NO
• Check the fiber cables for proper connection.
• Verify that the TX and RX cables on the media converter are connected to the RX and TX ports,
respectively, on the other device.
YES

NO
• The media converter has selected 10 Mb/s operation. If this is not the correct speed, disconnect
and reconnect the copper cable to restart the negotiation process.
YES - Flashing Amber
