Alternatively, you can manually set the port to 10BASE-T
half duplex, 10BASE-T full duplex, 100BASE-TX half
duplex or 100BASE-TX full duplex. You can also
manually set the port to 1000BASE-T. The port uses
Category 5 copper cabling with an RJ-45 connector. The
maximum segment length is 100 m (328 ft) over
Category 5 twisted pair cable.
