LED State Description

DUPLEX Green

Orange

The port is operating in full-duplex.

The port is operating in half-duplex.

Note - When a port on the AT-8411 line card is configured to auto-negotiate and is

connected to a 10/100 Mbps full-duplex port on another device, the current firmware

version returns the value 'half-duplex' for the Port Duplex Status parameter. As a result, the

Duplex LED turns orange instead of green.
