Core Product Positioning
The Cisco N9K-FAN-2RU is a user-replaceable hot-swappable fan tray developed for 2RU fixed-port Cisco Nexus 9000 switches. It delivers forced-air thermal cooling to maintain safe operating temperatures for switch ASICs, power supplies and interface circuits within data center environments. The fan tray supports intelligent variable speed control managed by NX-OS operating system, provides hardware fault alarm signals, and enables non-disruptive in-service replacement without powering down the host switch. Two airflow variants are commonly available: Port-Side Intake (PI) and Port-Side Exhaust (PE) to match standard hot/cold aisle data center rack layout standards.
2. Hardware Compatibility
Supported 2RU Nexus 9000 Fixed Chassis
N9K-C9396TX, N9K-C93120TX, N9K-C9332PQ, N9K-C9364C, and other 2RU Nexus 9300 series fixed switches
Confirm airflow direction (PI / PE) must match installed power supplies to avoid airflow conflict
Supported Operating System
Cisco NX-OS Software for Nexus 9000 Platform
Unsupported Platforms
1RU Nexus switches, modular Nexus 9500 chassis, Catalyst switches, Nexus 3000 / 2000 series
