Connecting the Network Cables
The AT-2973SX adapter has two fiber optic connectors (each with a
transmit and receive) for attaching the system to a compatible link partner,
or an IEEE 802.3z compliant Gigabit Ethernet switch. The AT-2973T
adapter has two twisted-pair connectors.
For the AT-2973SX adapter you need a fiber optic cable. For
specifications for this cable, 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 131.
For the AT-2973T adapter, you need a twisted-pair cable. For pin signals
and pinout information, see “10/100/1000Base-T Twisted-Pair Port
Connectors” on page 128 and “Console Port Pinouts” on page 130.
To connect a network cable to the adapter, perform the following
procedure:
Warning
The fiber optic ports contain a Class 1 LED 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.
2. For the AT-2973SX adapter, connect the other end of the cable to the
appropriate Ethernet fiber optic port. For the AT-2973T adapter,
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 “Physical Descriptions” on page 21
for a description of LED operation for each adapter model. For driver
installation and configuration instructions, refer to the software
configuration for a specific driver.
After you connect the system to the network and power is supplied, the
AT-2973SX adapter attempts to establish the connection at 1000
Mbps full-duplex only.
