Is there anyone who is having information about the Ethernet hub or the switch that can take power from the PoE or to be more precise power over Ethernet? The problem is that currently I am having few networks that I have to install and they are spread over a large area but there is no main wiring. I mean to say that there is source of power. Hence I am searching for the most cost effective solution that can be helpful in this case. If anyone is having effective solution for this kind of problem then let me know about that.
