The Cisco Nexus 3524 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. The Cisco Nexus 3524 switches 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.
