Troubleshooting
Follow the guidelines below to test and troubleshoot the installation in the
event a problem occurs.
If the PWR LED is OFF, do the following:
If the unit is installed on a desktop, check to be sure that the power
adapter is securely connected to a power outlet and that the power
adapter cable is securely connected to the back of the media
converter.
If the unit is installed in an AT-MCR12 chassis, check that the unit is
fully seated in the slot.
Verify that the power outlet has power by connecting another device
to it.
Try using another power adapter of the same type that came with
your media converter.
If the LINK LED for the twisted pair port is OFF, do the following:
Check that the end-node connected to the port is powered ON and is
operating properly.
Check that the twisted pair cable is securely connected to the twisted
pair port on the media converter and on the remote end-node.
Make sure that the twisted pair cable does not exceed 100 meters
(328 feet) and that you are using Category 5 or better.
Verify that both end-nodes connected to the media converter are
operating at the same speed. Both must be operating at 100 Mbps.
