Figure 4 Twisted Pair Ports
The AT-8024 and AT-8024GB Fast Ethernet Switches feature 24 twisted
pair ports. The features of the ports are described below.
Type of Connector
All twisted pair ports feature 9-pin RJ-45 connectors. (For the port
pinouts, refer to RJ-45 Twisted Pair Port Pinouts on page 70 in
Appendix A, Technical Specifications.
Speed
The ports are 10Base-T and 100Base-TX compliant and are capable of 10
megabits per second (Mbps) or 100 Mbps speed. You can set the port
speed manually or, since the ports are IEEE 802.3u Auto-Negotiation
compliant, you can let the switch set each port’s speed automatically.
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.
