Are 300 Series switches compatible with pre-standard PoE detection in old Cisco phones? They don't seem to be (a 7902G won't power on when connected to an SF302-08MP with firmware version 1.1). Is any special configuration needed on the switch to enable this detection?
Please note that the 200 and 300 Series switches now support Cisco Legacy POE as of September 2011, allowing it to deliver power to 7960, 7940, and other pre-standard phones and APs. Details provided at the following link:
