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:
