The Cisco Nexus 3548 and 3524 Switches (Figure 1) are based on identical hardware, differentiated only by their software licenses, which allow the Cisco Nexus 3524 to operate 24 ports, and enable the use of all 48 ports on the Cisco Nexus 3548. These fixed switches are compact one-rack-unit (1RU) form-factor 10 Gigabit Ethernet switches that provide line-rate Layer 2 and 3 switching with ultra-low latency. Both software licenses run the industry-leading CiscoNX-OS Software operating system, providing customers with comprehensive features and functions that are deployed globally. The Cisco Nexus 3548 and 3524 contain no physical layer (PHY) chips, allowing low latency and low power consumption. These switches support both forward and reversed airflow schemes and both AC and DC power inputs.
