Implicit implementation of the crossover function within a twisted-pair cable, or at
a wiring panel, while not expressly forbidden, is beyond the scope of this standard.

When connecting Switch to another Fast Ethernet switch, a straight or crossover
cable might 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:
