Hi Aditi,

I can access the schematic now. The schematic looks fine connection wise.

What is the input power source? Do you expect any transients? This is to know the need of any TVS.

Also, I am attaching POE section, you can go through it for bettter understanding.

Max voltage at the input is 48V and it will not go higher than it
