    Hi David,

    Can you help to clarify the issue? Are you saying that you set all ports for 30W but only 2 ports are operating correctly at 30W while the other ports only operate at 15W? Are you doing any type of port power management? Is your power supply able to power the entire load of each PSE port or is it limited? Also, have you tried taking an EVM to verify your solution/code?

    Thanks!
