Anyway, I wasn't talking about "real" Power Over Ethernet (PoE). I was describing jury-rigging something that just piggy-backed on that last length of cable between the switch and the SqueezeBox. I think the real PoE systems are sort of standardized on 48V. And I guess there are actually 4 free wires in the ethernet cable. -- jonheal Jon Heal says: Have a nice day! http://www.theheals.org/ ------------------------------------------------------------------------ jonheal's Profile: http://forums.slimdevices.com/member.php?userid=2133 View this thread: http://forums.slimdevices.com/showthread.php?t=21936 _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
