The Cisco Nexus® 3048 Switch (Figure 1 – N3K-C3048TP-1GE) is a line-rate Gigabit Ethernet Top-of-Rack (ToR) switch and is part of the Cisco Nexus 3000 Series Switches portfolio. The Cisco Nexus 3048, with its compact one-Rack-Unit (1RU) form factor and integrated Layer 2 and 3 switching, complements the existing Cisco Nexus family of switches. This switch runs the industry-leading Cisco®NX‑OS Software operating system, providing customers with robust features and functions that are deployed in thousands of data centers worldwide. The Cisco Nexus 3048 is ideal for big data customers that require a Gigabit Ethernet ToR switch with local switching that connects transparently to upstream Cisco Nexus switches, providing an end-to-end Cisco Nexus fabric in their data centers. This switch supports both forward and reversed airflow schemes with AC and DC power inputs.
