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:
