How the LibreRouter can power another device with POE Passthrough

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.internet-ethernet

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

Thanks @nicopace!
Can’t we connect the second device to inner most ethernet socket?
I’m thinking of a setup where you have a LibreRouter connected to a gateway at the WAN (outter most) socket, and you want to connect a second LibreRouter to it.

From what I understand, you the inner most connector is the POE-in, and the outer-most connector is the POE-out, and shouldn’t be connected the other way.

For #developers, It would be possible from software to make the POE-in socket the WAN connector, or maybe in the future for the router to detect what the socket is and use it without user intervention.
