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 your Switch to another Fast Ethernet switch, a bridge or a hub, a straight or crossover cable is 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:
