vPro utilizes the integrated network adapter. Currently add-in cards (fiber or otherwise) are not supported. However if they are willing to use multiple adapters they could user a fiber add-in card for high-bandwidth traffic, and a second wired connection for manageability.

Eu tentaria usar um conversor de mídia de ethernet para fibra em vez de outro cartão se você quiser se conectar via fibra e usar vPro.
