Explanation

When installing a fan module in a Cisco Nexus fixed-configuration switch, it's crucial to ensure that the airflow direction of the new fan matches the existing airflow configuration. Mismatched airflow directions can lead to inefficient cooling or even overheating of components, potentially affecting the performance or lifespan of the switch. Cisco offers fan modules in front-to-back or back-to-front airflow variants, and consistency is required for proper thermal management. These modules are also typically hot-swappable, meaning powering down the switch is not necessary.
