POE BeBox
The Be Box needs 18V AC, the multimeter says 21V on the power supply and the same after it’s been through about 8 meters of cat6 cable.

DIY Power Over Ethernet
I got fed up with the power cable trailing in front of the bathroom door to my ADSL router so I rigged up this simple power-over-ethernet thing. 100Mbit ethernet only uses two of the four pairs in the cat5 cable so I wired the other two to carry the power (see diagram).
