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 10/100Mbps Ethernet Switch to another 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 RJ-45 receptacle/ connector and their pin assignments:
