Hi
I have connected IP phone 7960 and Axis POE camera 212 onto a C3750 switch. I have enabled energywise on the switch and I am able to control the phone and camera with the power level control. The thing I don't understand is that the power usage for both the phone and camera are showing 4 W. The phone is suppose to be 6.3W and the camera is 3.8W. Is there a reason why it is showing 4W instead of it's actual power usage?

What version of code is running on this switch?

c3750-ipservices-mz.122-50.SE1.bin
Thanks

That release did not properly support displaying the actual power usage. That feature was added to 12.2(52)SE as part of the fix for CSCsz05235.

Thanks, but after I uploaded the new firmware into the switch, it still have the problem.
this is the boot info.
BOOT path-list : flash:c3750-ipservices-mz.122-52.SE.bin
Config file : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break : no
Manual Boot : no
HELPER path-list :

Auto upgrade path :

The IP Phone and the IP camera still shows the same 4W at the energywise interfaces list.
So what should I do? Thanks

What output do you get from "show energy usage children"?

I believe this points to the switch not being able to report actual power usage. The fix for the bug I mentioned added support for obtaining the "actual" (as opposed to "presumed") power consumption from the switch hardware (if supported). If the actual values are not seen in the CLI output, then the switch may be incapable of providing them.

Why we change the level, the power usage does not change?
