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. Comments?

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.

We are testing five phones running on a Linksys SRW208P that will only support full 15W on up to 4 of 8 ports. I can power up the switch while all phones are connected without any issues. I would expect your lower power switch will provide ample power. regards, Drew

It claims to need a 48V .13 amp wall wart if you power it that way, Ira
