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 media converter 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 media converter is installed in an AT-MCR12 chassis, check that

the unit is fully seated in the slot. Installing a redundant power supply

is recommended if the chassis is fully loaded with (a combination of)

AT-MC1004 or AT-MC1005/x Series Media Converters.

❑ Verify that the power outlet has power by connecting another device

to it.

❑ Try using another power adapter.

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 cable.

❑ Verify that the end-node is operating at 1000 Mbps and full-duplex

mode.
