14 Overview
Duplex Mode Switch
The 10/100 Fast Ethernet Switch must be set to the proper duplex
mode for all ports. The switch can be set to auto-detect the duplex
mode for ports 1 and 2, and for the MII connector; All other ports
must be set to either full or half duplex.
To change the duplex mode, change the Duplex Mode DIP switch
setting on the back of the 10/100 Fast Ethernet Switch. On the
DIP switch, for ports 1, 2, and the MII connector, down is auto-
detect, up is full-duplex. For ports 1 and 2 (the 10/100Mbps
variable speed ports), “Auto” means that the appropriate duplex
mode is set by the hub according to the capabilities of the device
connected, and “FDX” manually sets the ports to full duplex mode.
Regardless of the duplex mode setting, the speed setting of ports 1
and 2 is automatically detected.
For all other ports up is full duplex, down is half duplex, and the
switch numbers correspond with the port numbers. Note that it is
not necessary to turn off the device when changing the duplex
mode setting.
