Just a quick note about POE (power over ethernet). Basically what you see is not what you get :( . I have a Cisco 3524 switch with POE, and I also have an IP phone (Snom 100) which is also POE, but the two don't talk. It seems that there are more then one method of communication between the POE server (i.e. the switch) and the POE client (i.e. the phone). The issue has to do with how the phone asks the switch to turn on power on the particular port to which it is connected. From what I read of the specs (IEEE POE specs) is that there are a number of signaling methodologies in place. The power lines aren't hot all the time, and are activated only after a successful "handshake" between the client and server. In my case it seems that the Cisco 3524 and the SNOM 100 are not compatible for the POE portion. I researched this thouroughly, and it seems that some of the Cisco devices would be compatible, but I already have the 3524 :(.
