Duplex Mode
Each twisted pair port on the switch can operate in either half- or full-
duplex mode. The twisted pair ports are IEEE 802.3u-compliant and will
Auto-Negotiate the duplex mode setting. If the end node connected to a
twisted pair port on the switch is capable of full-duplex operation, the
switch sets the port to full-duplex. If the end node is capable of only half-
duplex, the port is set to half-duplex.
If desired, Auto-Negotiation on one or all of the twisted pair ports can be
disabled so that you can set the duplex mode manually through the
switch’s management software.
