Note
After the cable is properly connected at both ends, the adapter port
LEDs is functional. For descriptions of LED operation, see “AT-
2712FX/SC and AT-2712LX20/SC Adapters Physical Descriptions”
on page 17 or “AT-2912T Adapter Physical Description” on page 18.
After you connect the system to the network and power is supplied, the
AT-2712FX/SC and AT-2712LX20/SC adapters attempt to establish
the connection at 100 Mbps full-duplex. The AT-2912T uses
Autonegotiation to determine the connection settings.
