A.3 Switch's RJ-45 Pin Assignments - 10/100Mbps, 10/100Base-TX
When connecting your Switch to another Fast Ethernet 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:
