GE-DS-82 and 82-PoE Ethernet Managed Switch User Manual
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:
