When connecting your PoE Ethernet Switch to another Fast Ethernet switch, a
bridge or a hub and a straight or crossover cable are 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:
