3Set the MDI-II/MDI-X Switch (twisted-pair ports only)

To eliminate the need for crossover cables, the Radiance line cards have an MDI-IIto MDI-Xslide switch for each twisted-pair port. This switch is positioned directly behind its associated RJ-45 connector and allows simple setup in either straight-through (default) or crossover configurations. See the diagrams on pages 5 and 6 for the location of the switch.

When setting the MDI-IIto MDI-Xswitch, observe the positioning of the following symbols:

the parallel symbol (II) indicates a straight-through or parallel connection. (default)

the cross symbol (X) indicates a crossover connection.

These symbols are clearly marked on the printed circuit board. Simply slide the switch in the direction of the appropriate symbol. Use the following tables as a guide.
