Inline power - 802.3af

Picked up a 9975 and 8845 to play with in my lab, and they keep power cycling... look up the specs and figure out that the 3550 POE switch isn't 802.3af that these phones need. Works fine with 7940/7960 but not these newer models. DOH

Just keep this in mind when selecting a switch/phones for your lab :)
