Appendix B
RJ-45 Pin Specification
When connecting your FSD-series 10/100Mbps Ethernet Switch to another switch, a
bridge or a hub, a modied crossover cable is not necessary. Each port of the Switch
is auto-MDI detection. That means you can direct connect the Switch to any Ethernet
devices with a Category 5, UTP straight wire.
However, the following diagram and tables also show the standard RJ-45 receptacle/
connector and their pin assignments for the switch-to-network adapter card connection,
and the straight / crossover cable for the Switch-to-switch/hub/bridge connection.
