Twisted Pair Ports
The AT-FS724L switch has 24 10Base-T/100Base-TX twisted pair ports. Each
twisted pair port features a RJ-45 connector. The maximum operating distance
for the twisted pair ports is 100 meters (328 feet) when operating at either
10 Mbps or 100 Mbps.
Port Speed
The twisted pair ports are compliant with the 10Base-T and 100Base-TX
standards and are capable of either 10 Mbps or 100 Mbps operation. Since the
ports are IEEE 802.3u Auto-Negotiation compliant, the switch will set the
port speed automatically. With Auto-Negotiation, the speed of the ports are
set automatically by the switch after it determines the speed of the end-node
connected to the port. Auto-Negotiation is designed to ensure that the port on
the switch and the end-node are operating at the same speed and that they
are communicating at the highest possible common speed between the
devices. For example, if an end-node is capable of only 10 Mbps, the switch
then sets the port connected to the end-node to 10 Mbps.
