Switch with PowerOverEthernet for a BaseStation

Hi, list!

We have actually 4 BaseStation (but in the future we will buy at least other 2). Now want my Boss to buy a PoE-Switch at which we connect all BaseStation. This Switch has to supply power, too.

Now, I'm not sure (I don't know PoE in detail) if I can use every PoE-Switch. I searched in Internet and I found a Netgear FS108P. It's cheap and it will be enough for us. Can I use it with our BaseStation or have I to use the power supplier of the BaseStations, too?

Thanks a lot for your answers!
