Hi Sir

I measure the POE Voltage about the initial power up status below figure. What is the status in blue line as the TPS23753APWR spec?

Hello Chen Bogey,

Thank you for your question. If this is a type 1 PD, this might not be an issue, but if it is type 2 then this is a problem.

Additionally, I would like to know which PSE device you are using, and type 1 or type 2?

Thanks!

Regards,

Michael Pahl

Hi Sir

I don’t sure which is type, but I know the R51 placed to 90.9Ω on CLS from our circuit. Classification level should be 3.

Hello Chen,

Thank you for your answer. Class 3 in this case will be Type 1 for your PD.

Do you know the type of the PSE?

Alternatively, do you know how much power the power sourcing equipment can send? 15.4W or 30W? Thank you!
