Setting the Duplex Mode
Each port of the device can be set for half-duplex or full-duplex operation. The two 10/100Mbps ports can be set to either full-duplex or auto-detect duplex mode. At half-duplex operation, packet transmission and reception do not occur simultaneously, thus communication speed is limited to 100Mbps using 100BASE-TX mode and 10Mbps using 10BASE-T mode. At full-duplex operation, packet transmission and reception occur simultaneously, thus communication speed is doubled to 200Mbps using 100BASE-TX mode and 20Mbps using 10BASE-T mode. Full-duplex operation can be used on links between the 10/100 Fast Ethernet Switch and any device (or station) that supports full-duplex operation.
Set the duplex mode through the duplex mode switch at the rear of the device. To set a port to full-duplex operation, slide the corresponding duplex
