Hi,
Hope you can help.
I'm running 3560-48 and 24 PS-L's (640W PSUs) with non Cisco POE edge devices. The issue I'm having is these devices won't draw much more than 3-6 Watts but the switch wants to use 15.4W per port, depleting my POE budget! I have tried setting "power inline auto max" but the port shuts down.
I have seen you can use the "power inline consuption" command, but its not a recognised command as I'm only running an L not an E image.
Is there anything else I can do other adding a 2nd PSU to these switches to increase my global POE budget? I have attached my POE environment, please note I need to use at least 38 ports hence my conumdrum.
I look forward to your feedback.

Hi
if ports shutting down something else is wrong ,it shiuldnt do that
i just tested it to check on a 3650 as below results , 30w port running 7821
Gi1/0/40 auto on 3.2 IP Phone 7821 1 30.0
Set the port to 4000kw lowest i can go back from 30000kw
Gi1/0/40 auto on 4.0 IP Phone 7821 1 4.0
sh int g1/0/40
GigabitEthernet1/0/40 is up, line protocol is up (connected)

end
what version are you running on the switch ? are you giving it enough power to stay up , try increasing it ....
