Re: power for 7900 series phones

These phones do not support Cisco pre-standard PoE. They support 802.3af only. If your PoE switch does not provide 802.3af power, you will have to use a power injector or power adapter. Take a look at the phone specifications in the following link.

Hope this helps. If so, please rate the post.
