APPENDIX A

RJ-45 PIN SPECIFICATION

When connecting your FSD-series 10/100Mbps Ethernet Switch to another switch, a

bridge or a hub, a straight or crossover cable is necessary. Each port of the Switch

supports auto-MDI/MDI-X detection. That means you can directly connect the Switch to

any Ethernet devices without making a crossover cable.

The following table and diagram show the standard RJ-45 receptacle/ connector and their

pin assignments:
