There's 8-port non-gigabit/transformer-based PoE injectors on eBay, you can use one of those as a PoE extractor from all the lines. But there is the risk that as they are all connected, the same PoE is going back to customers and could damage any hardware connected to their outlets that is not going through a PoE injector. The solution to that would be getting your electronics tech to install diodes in the PoE injector-as-extractor.

The switch they use gets power from the set top boxes via the coax cables. As long as any one of the set top boxes in the building is turned on, then the switch has power. I was curious if there's an ethernet switch with a similar capability. I've got a place where I'd like to put a managed switch, but it would be easier and cheaper to supply a few PoE injectors than to install an outlet. Anybody heard of such a beast, or am I hunting the white whale?
