10BASE-T/ 100BASE-TX
Ports
The Switch 4500 has 24 or 48 auto-negotiating 10BASE-T/100BASE-TX ports
configured as Auto MDIX (cross-over). These ports automatically provide the
appropriate connection. Alternatively, you can manually set these ports to
10BASE-T half-duplex, 10BASE-T full0-duplex, 100BASE-TX half-duplex or
100BASE-TX full-duplex. The maximum segment length is 100 m (328 ft) over
Category 5 twisted pair cable.
