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.3 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:
