Hi,

 

You can use 9900 series along with camera with 802.3af  as per the link below link.

https://supportforums.cisco.com/discussion/10808941/poe-class-4-9951-phones

if you refer table 2.1 , it says 802.3at  for external add-on devices.

Hi, Datasheet of 9900 says

Hi,

 

Datasheet of 9900 says that it is a Class 3/class 4 device .Class 3 device requires  15.4W under 802.3af.

You can give a try with 802.3af.

You'll need to force the HP

You'll need to force the HP switch to push 20.0w PoE to the port.  

 

Make sure the HP switch still has ample power left or has excess power to push 20.0w.
