Ethernet Ports
The RXi2-BP provides four Ethernet ports: three RJ45 ports at the front, and one at the bottom.
All Ethernet ports support 10/100/1000 Base-T. For a proper 100/1000 Mbit connection, a CAT5 cable
is recommended.
The three RJ45 ports located at the front (ETH1-3) are connected to Intel I210 devices located on the
carrier.
The one RJ45 port located at the bottom (ETH0) is connected to the on-module Realtek RTL8111EP
Ethernet Controller.
