The KeContact M10 features two functional Ethernet ports on its front side, ETH0 and ETH1. As shown in the picture below, these two ports have different functions. ETH0 is used to connect the P20 wall boxes to the M10. To do this, patch panel and network switches are required. We call the hereby created network the "KeContact LAN". ETH1 can be connected to any public/company LAN or even to the Internet directly
