Troubleshooting

Troubleshooting Guidelines

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 LNK 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 either 10

Mbps.

❑ Make sure no configuration changes have been made. If so, you must

reset the media converter by powering OFF and then powering ON the

unit.
