When connecting the Switch to another Fast Ethernet switch, a straight-through or
crossover cable might be 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 RJ45 receptacle/ connector and their pin assignments:
