Sorry about the original thread break off, I've been unable to find the original one. Hi Octavio, We are using Aastra 480i phones powered by PoE. During the testing we decided to drop the Linksys SRW208P as it is extremely noisy due to the fans, not suitable for an office environment. We continued testing with Netgear FS116P switches. These have 8 PoE ports plus 8 non-powered ports. Completely silent, no fans. Our testing was done with 5 phones per switch as our call centre is laid out in "pods" with 5 seats per pod and will not require more devices powered by PoE. I did not look into the issues of PoE class as there were no problems meeting our requirements with the equipment we had. Perhaps the Cisco switches are more particular about PoE class, they are much more complex devices. I like Cisco gear, they make good products but they tend to be over-featured and over-priced for many applications. We have had 5 of the Netgear switches in production for almost a year now, each powering 5 Aastra 480i phones without any issues whatsoever. regards, Drew -- Drew Gibson Systems Administrator OANDA Corporation www.oanda.com ___ -- 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

I can't for sure with the Aastras, but I know a Polycom 601 only draws about 3.5-4 watts according to the command line of the switches we use (Nortel 5520). I can't imagine a 480i uses much more than that. Regards, - Brad The contents of this e-mail are intended for the named addressee only. It contains information that may be confidential.

[asterisk-users] POE draw on Aastra 480i
Anyone know what the POE draw is for the Aastra 480i phones? We have switches that will do 15 watts on 12 ports but only do 7.7 watts on all 24 ports. A Cisco 3560 switch will do 15.6 watts on all 24 ports. Just trying to find out if we need that much power. Can't seem to find any info on the Aastra site.
