Hi Patrick,
The problem here is that the ws-c4224v-8fxs was EoL before the standards for PoE were ratified and 802.1af PoE became the Industry standard. This switch only supports Cisco Pre-Standard PoE and the 7975 requires at least Class 3 power as supplied by the newer Cisco Models (3560, 3750 etc.)Cisco Pre-Standard power works fine for older IP Phone models like the 7940/7960's.
EoL Notice;
Hope this helps! Sorry man!
