Connecting the Network Cables
After you install the adapter in your PC, attach the system to a compatible
link partner or an IEEE 802.3z compliant Gigabit Ethernet switch.
The AT-2973SX adapter has two fiber optic connectors, each with a
transmit and receive connector. This adapter requires a fiber optic cable.
For cable specifications, see the AT-2973SX adapter data sheet.
Note
For information about cleaning a fiber optic connector, see Appendix
B “Cleaning Fiber Optic Connectors” on page 171.
The AT-2973T adapter has two twisted-pair connectors and the
AT-2973T/4 adapter has four twisted-pair connectors. Both adapters
require twisted-pair cables. For pin signals and pinout information, see
“10/100/1000Base-T Twisted-Pair Port Connectors” on page 168.
To connect the network cables to an AT-2973SX, AT-2973T, or
AT-2973T/4 adapter, do the following:
Warning
The fiber optic ports contain a Class 1 laser device. When the ports
are disconnected, always cover them with the provided plug.
Exposed ports may cause skin or eye damage

1. Connect one end of the cable to the adapter.
– For the AT-2973SX adapter, use a fiber optic
cable.
– For the AT-2973T and AT-2973T/4 adapters, use
a twisted-pair cable.
2. For the AT-2973SX adapter, connect the other end of the cable to the
appropriate Ethernet fiber optic port. For the AT-2973T and
AT-2973T/4 adapters, connect the other end of the cable to another
twisted pair port.
Note
After the cable is properly connected at both ends, the adapter port
LEDs should be functional. See “AT-2973SX Adapter Physical
Description” on page 17, “AT-2973T Adapter Physical Description”
on page 18, or “AT-2973T/4 Adapter Physical Description” on
page 21 for a description of LED operation for each adapter model.
