operating at 10Mbps.

Duplex Mode Switch
The 10/100 Fast Ethernet Switch must be set to the proper duplex mode for
both ports. 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, down is half-duplex, up is full-duplex, and the switch numbers
correspond with the port numbers.
