All Allegros with network card | All Allegros with network card expansion slots support the '''In-Line Mode''' by default. All expansion cards have either '''2''' or '''4''' network ports. Each card forms '''1''' or '''2''' bridges. On expansion cards with '''4''' ports, the two left and the two right ports are the bridge pair. | ||
