[cisco-voip] PoE Question

[Voll, Scott]

I thought the 7911's were power hungry too.

It is only the 7970s ad 71s that are the power hogs.  The 41/61s with
gigabit Ethernet that use slightly more power, but not the 15.4 watts
that the executive handsets use.

Well it depends.

 

My understanding is you can fully populate a 24 port PoE switch with
anything.

 

Or a 48 port with the older phones using the 6.3 watts.

 

But if you are using the newer phones which use twice the watts you can
only plug in about half.

 

Doesn't make much sense to me that cisco would do that..... but that's
what my Partner / reseller is telling me.

Does anyone have a link on Cisco's web site that will explain the power
budgeting for PoE on their switches.  Basically I'm looking for proof
that it's either possible or not to have phones plugged into every port
on a switch and not cause any problems with power.  I've heard both that
you can't use all the ports and that you can, so I need the definitive
answer.

 

 

thanks again!
