This allows youto connect network devices to each port using either anormal straight-through TP (twisted pair) cable or a‘crossover’ TP cable.Any port can therefore be used to connect to anotherswitch port, server, or workstation without additionalconfiguration.Autonegotiating 10/100 Mbps PortsEach 10/100 Mbps port automatically determines thespeed and duplex mode of the connected equipmentand provides a suitable switched connection. The10/100 Mbps ports can operate in either half-duplex orfull-duplex mode.
