Figure 3-1. 10BASE-FB Module Dip Switch Locations

Note: The Port-Switching 10BASE-FB Module is also available as a two-port module (Model Number 5102M-FBP) for installations that do not require four fiber ports. When using the switches for the two-port module, all switches operate identical to the switches on the four-port module with the exception of port 3 and port 4 switches. These switches do not perform any operation.
