Is that 30 watts per port? If so this could be something we might be interested in as we're pushing out 15.4 now and still can't get our LWAP's to totally power up.

No this is enhanced PoE in the range 15.4W to 20W/ port. 30W/ port is expected in the new IEEE802.3at std in ~Sept'09.

EnergyWise is a Cisco architecture to manage and optimize power consumed on the network. It is expected to FCS across the switching portfolio (Cat3K, Cat4K, Cat6K) in CY'09.
