Just beware that not all PoE powered devices are IEEE Standard 802.3af PoE. Lots of devices I deal with are something called "passive" poe where there is no handshaking protocols, and the end devices are typically expecting less than the "standard" 48V. For example, virtually all of the Ubiquiti gear uses "passive" PoE in the range from about 10-24 Volts or something (from memory, please check). The Nanostation comes with a little injector that just puts a nominally 12V DC power supply on the ethernet cable (two wires +12V, two wires ground). There is some resistive voltage loss in long runs of cabling. It is not uncommon for people to use 15V or 18V in situations like that. In anything under about 100 feet, the supplied 12V adapter is going to be just fine. -- Russell Senior, President russ...@personaltelco.net _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
