I'm trying to use a PoE Ethernet Brick to allow me to communicate with a distant IMU Brick.  I'm trying to get it to work initially with just my RED Brick.

 

I've tried it on top and below the RED Brick but I don't see any DHCP requests coming from it.  I'm guessing that I need to configure it through the RED Brick first.  I'm documenting here in case it helps someone else (or me in the future...) and in the hope that someone might give me pointers.

 

First, I note that PoE will power the RED either atop or below it.  The RED only sees the Ethernet interface if the RED is below.

 

 

I put the Ethernet on top of the RED.  I connected to the RED using USB.  I enumerated devices through brickd on the RED.  I did not see anything other than the RED.

 

Help?

I decided to just use a Linux solution.  I configured the Ethernet Brick in /etc/network/interfaces:

 

auto tf0
allow-hotplug tf0
iface tf0 inet dhcp

 

Seems to work well.  (I'm much more comfortable with the command line than menus anyway.)
