Hi, I'm not clear on how to use Power--over-Ethernet, specifically with Polycom phones. What I understand, is that by buying the Polycom 501 with the 802.3af cable bundle, I simply connect my phone, through the Polycom provided "special" RJ-45 cable, into a PoE capable switch, and voil?! Is this true? And if so, what happens when the Phone doesn't connect directly to the switch? (let`s say there is wiring in the wall that goes to a patch panel, for example. Do I need to change all the wiring in the office?) Mike -------------- next part -------------- An HTML attachment was scrubbed...

A POE switch will put power on what ever line is connected to it, so if your polycom plugs into a wall plate with cat 5 cable that runs back to a port on the POE switch then you have power all the way to the phone.

This cable is black, about 4 ft long and has an RJ45 plug (goes into the phone) on one end and an RJ45 Jack (plugs into the patch cable) on the other. Near the RJ45 jack there is a little black box that does the power conversion from 802.3af into whatever the phone needs. There is also a (not sure what it's called) spot for you to plug in an AC adapter if necessary. There's a good picture of one here: http://voipstore.atacomm.com/Shops/ViewItem.aspx/27934028032-38040890624.htm As long as you have CAT5 or better cable between the switch and the RJ45 jack on the special cable you will be fine. Using a patch panel and a wall jack is also fine as long as it is CAT5 or better. You just can't have another switch or hub between your POE switch and the phone. -Dave
You don't need to change any wiring. Just be sure that the LAN wiring terminates at a PoE LAN switch (PoE would not be passed through an intermediate switch). You will get an AC adapter with your phone. If the phone fails to power up, you can plug the adapter into the thingie in the PoE cable (not the phone). Also, the IP601 has a 24V AC adapter while the IP501 has a 12V adapter.
