IEEE802.3af uses same 4 wire as data. thats what Polycom uses. the way i'm seeing it we are better off with poe switch(looking at the price).

For the price of one of those multi-port injectors, you can come close to the price of a new Netgear or 3Com PoE switch. The injectors typically add power to the unused pairs (mode B PoE). This means you can't use them on anything better than fastethernet. When switches do PoE natively, they put the power on the data carrying pairs (mode A PoE), so they can do gigabit ethernet. I think PowerDsine makes a PoE injector that uses mode A, and so it can do gigabit ethernet. - Noah _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
