The NXA-FAN-30CFM-B is a Cisco reverse airflow fan engineered for the Nexus 2000 Series Switches. Designed to improve thermal management, this fan reverses the standard airflow direction, directing hot air out of the chassis to maintain optimal operating temperatures. With a 30 cubic feet per minute (CFM) airflow rating, it provides a reliable cooling solution for high‑density networking environments. The fan is compatible with Cisco Nexus 2000 Series Switches, ensuring seamless integration and replacement without impacting system performance. Its robust construction and low noise profile make it suitable for data centers and enterprise deployments requiring efficient, reliable airflow control.
