Can i Change the PoE Class from 4 to 3

[JeremyClarkson]

Hi,

I have IP cameras that are running at Class 4 power (which are not working)
I have IP cameras that are running at Class 3 power (which are working)

Any idea if i can stop auto negotiate the power settings and change class?

Thanks

Very often these cameras need LLDP-MED. Which cameras do you use ?
