5. APPENDIX A RJ45 Pin Assignments

5.1. A.1 10/100/1000Mbps, 10/100/1000BASE-T
When connecting your 10/100/1000Mbps Cellular Gateway to another device, a bridge or a hub, a straight-through or
crossover cable is necessary. Each port of the Cellular Gateway supports auto-MDI/MDI-X detection. That means you
can directly connect the Cellular Gateway to any Ethernet devices without making a crossover cable. The following
table and diagram show the standard RJ45 receptacle/connector and their pin assignments:
