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.
