If the bridging 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

Check that the twisted pair cable is securely connected to the twisted
pair port on the bridging converter and on the end-node.

Series converter is operating at the same duplex mode or that both
the AT-GS2002 and the end-node are both configured for Auto-
Negotiation.
