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:
