APPENDIX A NETWORKING CONNECTION
A.1 Switch‘s RJ-45 Pin Assignments
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:
