Cisco N3K-C3064-FAN-B | Nexus 3064 Fan Module, Reversed Airflow, Hot-Swap

Q: What is the difference between N3K-C3064-FAN and N3K-C3064-FAN-B?
A: The N3K-C3064-FAN has forward airflow with port-side exhaust, while the N3K-C3064-FAN-B has reversed airflow with port-side intake. The -B model draws air from the front ports and exhausts through the rear, suitable for cold-aisle containment setups.

Q: Can I replace the fan module while the switch is running?
A: Yes, the N3K-C3064-FAN-B is hot-swappable and can be replaced without powering down the switch. However, it should be replaced within 1 minute to prevent overheating and potential system reload.

Q: Do I need to replace the power supplies when changing the fan module airflow direction?
A: Yes, when changing airflow direction you must also replace the power supplies to match. For reversed airflow, you need N2200-PAC-400W-B power supplies to ensure consistent airflow direction throughout the chassis.

Q: Which Nexus 3064 switch models are compatible with this fan module?
A: The N3K-C3064-FAN-B is compatible with Cisco Nexus 3064-X, 3064-T, and 3064-32T switches in the Nexus 3000 Series that require reversed airflow cooling.

Q: What happens if I mix airflow directions in my Nexus 3064 switch?
A: Mixing airflow directions between fan modules and power supplies can cause inadequate cooling and thermal issues. Always ensure all components (fans and PSUs) have matching airflow directions for proper system operation.
