DIP Switches
The DIP switches are used to manually configure the operating
characteristics of the ports. These characteristics include the port speed,
duplex mode, and auto-negotiation.
On the 100Base-FX fiber optic port, you can manually set the duplex
mode to either half-duplex or full-duplex.
On the 10/100Base-TX twisted pair port, you can manually set the speed
of the port to either 10 Mbps or 100 Mbps, set the duplex mode to either
half-duplex or full-duplex and enable or disable auto-negotiation.
Enabling auto-negotiation will automatically set the port’s speed and
duplex mode.
The DIP switches are located on the board. Refer to Figure 32.
