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
