[cisco-voip] PoE Question

[Lelio Fulgenzi]

I'm pretty sure this is specific to the switch you are using. For example, I think the one-piece switches have enough juice to power a phone on each port using PoE (cisco inline power) but the chasis switches like the 4000 require external power supplies if you want to use a lot of phones. And boy do they generate heat!

  Subject: [cisco-voip] PoE Question


  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!
