What's wrong with a C7 plus a POE splitter? Just make sure you buy one compatible with your switch, or buy as a matched pair with injector or your eyes will go blury with 24v passive, 48v passive, 802.3af, 802.3at, lions tigers and bears, oh my.
Modern gear uses 802.3. 'af' up to 15 watts, 'at' up to 30 watts. Some older gear and some second tier manufacturers still use proprietary POE techniques or one of the semi-standard passive POE conventions. I strongly recommend against anything that is NOT 802.3af/at if you plan on keeping it more than a short while.
