yeah, CISCO screwed up in the compliance spec listed on the data sheet when they stated 802.3af instead of 802.3at. They clearly state the peak draw is 17 watts. 802.3af can only deliver 12.5-13 watts actual. Interestingly, if you follow their power injector listed as compatible it is for the 802.3at compliant version with 25-30 w delivered. So they just assumed everyone would by their adapter or switch , LOL.
