CnPulse 100MB link

Hi,

Is a tower with FM and the cables is hard to get 1Gb negotiation. With Cat8 cables is no problem with the POE on the device, but If I POE with the cnPulse the cable link at 100Mb. If I use the aux port for sync is working a 1Gb.

I now using the standar conection for the cnPulse
