PRODUCTION DATA
The requested class is the classification the PSE measures during mutual identification prior to turn-on, whereas the assigned class is the classification level the channel was powered on with based on the power allocation setting in register 0x29h. In most cases where the power allocation equals or exceeds the requested class, the requested and assigned classes is the same. However, in the case of power demotion, these values differ.
For example: If a 4-pair Class 8 PD is connected to a 30-W (Class 4) configured PSE port, the requested class reports "Class 8", while the assigned class reports "Class 4".
The requested classification results are available in registers 0x0C-0F.
The assigned classification results are available in registers 0x4C-4F.
There is no Assigned Class assigned for ports and channels powered out of manual and diagnostic mode.
