AT-8413
AT-8413GB/T
LED State Description
DUPLEX Green
Orange
The port is operating in full-duplex.
The port is operating in half-duplex.
Note - A GBIC image is always visible on the GBIC slot of the AT-8413GB/T line card image
even if there is no GBIC physically present in the slot.
Note - Status information for the AT-8413GB/T ports will always be reflected on the RJ-45
port image regardless of whether the port that is in actual use is the GBIC port or the
twisted pair port.
Note - When the 10/100/1000Base-T port of the AT-8413GB/T line card is configured to
auto-negotiate and is connected to a 10/100Mbps 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.
