    The DGS-3324SR is a modular Gigabit Ethernet backbone switch designed for adaptability and scalability. The Switch provides a management platform and uplink to backbone for a stacked group of twelve DGS-3324SR Layer 3 switches in a ring or chain topology arrangement. Alternatively, the Switch can utilize up to twenty-four Gigabit Ethernet ports to function as a central distribution hub for other switches or switch groups, or routers.
