Cisco N3K-C3048-BA-L3 48-Port Layer 3 Network Switch

The Cisco N3K-C3048-BA-L3 is a 48-port Layer 3 network switch in the Nexus 3048 family, engineered to deliver dense interconnectivity and routing capability for data-center and enterprise networks requiring scalable, centralized traffic management and predictable performance across many devices. This model specifies reversed airflow with port-side intake and AC power, a cooling and power configuration commonly chosen for standard data-center racks where front-to-back airflow and conventional electrical feeds are used. As a Nexus 3048 device, it provides Layer 3 switching to route traffic between networks and VLANs, supporting efficient intra-network communication for servers, storage, and other endpoints within a single fabric. The part number N3K-C3048-BA-L3 identifies this exact configuration within Cisco's Nexus lineup.
