Overview The Cisco N9K-C9300-FAN2-B= is a fan tray designed to pull cold air into compatible Cisco Nexus 9300 switches, ensuring that internal components stay within their optimal temperature range. This cooling solution supports sustained high traffic loads by maintaining proper airflow, which helps preserve switch performance and reliability. It is specifically built for Nexus 93128TX, 9336PQ ACI Spine, and 9396PX models, making it a precise fit for these high-density network environments. Key features Cold air intake design that aligns with the Nexus 9300 switches’ airflow pattern to optimize cooling efficiency Hot-swappable module enables quick fan replacement without powering down the switch or interrupting network operations Compact and lightweight construction, weighing approximately 0.88 pounds, for easy handling during maintenance Durable build quality suited for frequent service in crowded data center racks Supports cold aisle and hot aisle data center layouts by maintaining consistent airflow direction Helps prevent heat-related performance degradation and hardware failure in dense 10, 40, or 100-gigabit network setups Key specs Compatible models: Cisco Nexus 93128TX, 9336PQ ACI Spine, 9396PX Airflow direction: cold air intake Weight: approximately 0.88 pounds Hot-swappable: yes Installation and maintenance Installing the fan tray is straightforward and takes only a few moments, allowing network administrators to quickly replace a failing fan without shutting down the switch. This hot-swappable design minimizes downtime and helps maintain continuous network availability, which is critical in enterprise and data center environments. Its manageable size and weight make it easy to handle even in tight rack spaces. Ideal uses and environments This fan tray is well suited for data centers that implement cold aisle and hot aisle cooling strategies, ensuring that the Nexus 9300 switches receive the proper airflow to operate efficiently. It is also a practical spare part for campus networks and branch offices that rely on Cisco Nexus switches, helping to reduce downtime in case of fan failure. The tray supports high-performance network environments with dense 10, 40, or 100-gigabit traffic, making it a reliable choice for expanding or maintaining Cisco Nexus deployments.
