The LibreRouter has the capacity of powering devices that you connect to it over ethernet cable with a feature called “POE Passthrough”.
In order to use it you need to connect the second device to the outer most ethernet socket.
Once you do that, as we haven’t yet developed the user interface for this functionality, you will have to enable it from the commandline.
BE VERY CAREFUL when enabling this functionality, as it will make power run over the ethernet cable that you connect to it, and if the device that is on connected to the other side is not POE capable, you might end up burning its network adaptor.
To do so, connect to the device over SSH, and enable it manually:
echo "1" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio1/direction echo "1" > /sys/class/gpio/gpio1/value
