We have launched a BBB PoE cape here, it will be available for sale soon: https://www.n-fuse.co/devices/SBCPoE-BBB-Power-over-Ethernet-Cape-for-BeagleBone-Black.html If you want one, you can contact me.

C3-Wireless has developed a fully 802.3af-compliant PoE cape as part of an internal project. We are trying to determine if there is enough demand to release it as a commercial product. We would need to build a minimum of 1000 units to make the price affordable. Do you think crowd-funding would be a good approach? I'd love some feedback at ccoll...@c3wireless.com.

The BeagleBone Black would only receive power from the Ethernet Port without using the 5V DC Port or microUSB Port. If PoE is not available by default, are there possibilties to upgrade by using a cape or an additional circuit? Remember that there are two forms of PoE. One is the full architected 802.3af version, which is 48V with a handshake to establish things like current requirement, and then there is the simpler passive PoE which just pushes typically 12-24V over the power pins (+ is 4-5, - is 7-8). The PoE pins on the BBB (if I remember correctly) are not used as PoE and are either grounded or connected to ground by a resistor, either way no use. However you can get PoE injectors such as:- http://www.rfelements.com/en/products/power-over-ethernet/passive-poe/ The one on the left would be used to power a BBB and the one on the right would be used to inject the 5VDC into the cat-5 cable. However be careful as voltage drop across cat5 is bigger than one might imagine, so you would be better putting 12VDC into the injector and then connecting a 12V - 5V converter (either a car USB adapter or one of the little DC-DC converter modules) and pluging that into the BBB as it will be a better 5VDC.
