Hii
I have cisco 9300 48P with 470 Poe watt, connect IeeePD default using 15.4 watt so only 30 device able to get connected. no enough power available for another device. when I see on Power inline policy device utilize not more then 9 watt. When i set it on static 10 watt power deny to PD.
i have same issue earlier with 2960, there was option in power inline consumption , I set power 10 watt it's working.
but in 9300 48P no such option available.
