Twisted Pair
Ports
The AT-FS708 Fast Ethernet switch features eight twisted pair ports. The
features of the twisted pair ports are explained in the following sections.
Type of Connector
All twisted pair ports feature 8-pin RJ-45 connectors. (For the port pinouts,
refer to “RJ-45 Twisted Pair Port Connectors” on page 35.)
Speed
The ports are 10Base-T, and 100Base-T compliant and are capable of 10
Mbps and 100 Mbps speeds. The ports are IEEE 802.3u Auto-Negotiation
compliant. With Auto-Negotiation, the switch automatically matches the
highest possible common speed between each switch port and each end-
node. For example, if an end-node is capable of only 10 Mbps, the switch
sets the port connected to the end-node to 10 Mbps.
Duplex Mode
Each twisted pair port on the switch can operate in either half- or full-
duplex mode. The twisted pair ports are IEEE 802.3u-compliant and will
Auto-Negotiate the duplex mode setting.
Note
In order for the switch to set the duplex mode for each port correctly,
the end-nodes that you connect to the switch ports also need to be
configured for Auto-Negotiation. Otherwise, a duplex mode
mismatch can occur, affecting network performance. For further
information, refer to “Duplex Mode” on page 17.
