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.
A.2 10/100Mbps, 10/100BASE-TX
When connecting 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, 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:
