Other Parts Discussed in Thread: TPS2375

Hi.


Im trying to get a 54 volts Vdd with the TPS2375. It looks nice with until the final stage, PD powered. 
PG pin gets high, and Vdd powers up, but only for a short time.
My PSE is an ZyXEL GS1100. It doesnt say that it support IEEE 802.3af, but it supports IEEE 802.az standard. Is that the reson why my power over ethernet doesnt function?
My ILIM resistor are not correct on this schematic.
