A.1 Switch's RJ-45 Pin Assignments
When connecting your 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:
