When connecting Switch to another Fast Ethernet switch, a straight-through or

MDI-X detection, meaning 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:
