Probably a POE switch, we use lots of POE splitters on the site where the
Pis will go already, failing that we have some injectors too kicking around

I'll try and dig out a Micro USB cable and try splicing one of the DC
cables I already have.  I was hoping that I wouldn't have to do that but I
guess with a couple of connector blocks it will do if it's in a nice neat
box :-)
