The N56128-FAN-F is a fan module designed for the Cisco Nexus 5000 Series switches, providing reliable front‑to‑back airflow to maintain optimal operating temperatures. This unit is specifically engineered for port side exhaust, ensuring efficient heat removal from the front of the chassis while directing warm air toward the rear. It supports the modular fan architecture of the Nexus 5000, allowing for scalable cooling solutions in high‑density data center environments. The fan module is compatible with standard Cisco Nexus 5000 hardware configurations and is intended to enhance airflow management and system reliability in enterprise networking deployments.
