Switch's RJ-45 Pin Assignments

1000Mbps, 1000Base T
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.

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:
