Please log in for more thread options A collegue of mine insists that it is impossible for a port to have gigabit speed while simultaneously using 802.3af PoE. Can anyone please confirm or deny? There's a round of beers running on this one. -RFH | ||||||||||||||||

Please log in for more thread options PoE works just fine on Gigabit speeds. Most of Cisco's phones are Gigabit capable and are powered using PoE. | ||||||||||||||||

Done all the time and has been out for a couple years now. In the Cisco world the 7941G-GE and 7971G-GE phones are gigabit, both of them use PoE. Pretty much all switches from the 3560 on up offer a version of Gig PoE, ie 3560G-24PS, 3750G-24PS, etc. | ||||||||||||||||

I think he is saying that the port will then not push gig throughput, not that PoE doesn't run on gig ports or something. Can anyone with an IP phone run a ftp test to a local server and see the throughput they get? | ||||||||||||||||

I believe he is refering to how in one mode of PoE it uses the "unused pairs" but in Gigabit there are no unused pairs so how could it work. | ||||||||||||||||
