Appendix A: RJ-45 pin assignment and

cable system

A.1 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:
