16 or 24 RJ-45 10/100 Dual Speed Switching Ports
There are 16 or 24 RJ-45 ports on the front panel. The
speed and full or half-duplex modes of the ports are
automatically determined when users connect the switch
to 10Base-T and 100Base-TX devices.

Connecting to a Desktop
The switch is connected to the desktop, to form a small
network. You can build the network as shown in the

To improve the network efficiency, it is better to have 200
Mbps full-duplex operation between the server and
switch, if the LAN adapter on the server can operate in
full-duplex mode.
