Understanding the CN3K-FAN30CFM-F=
The CN3K-FAN30CFM-F= is a Cisco product SKU associated with cooling fan modules designed for Nexus 3000 Series switches. While Cisco’s public documentation does not explicitly detail this specific model, insights from authorized distributors like itmall.sale indicate it is a 30 CFM (cubic feet per minute) fan tray engineered to maintain optimal operating temperatures in high-density network environments.
Key Features and Technical Specifications
- High Airflow Capacity: Delivers 30 CFM to prevent overheating in switches handling intensive workloads.
- Hot-Swappable Design: Allows replacement without powering down the switch, minimizing downtime.
- Redundancy Support: Works in tandem with other fans to ensure continuous cooling even if one module fails.
Compatibility and Deployment Scenarios
The CN3K-FAN30CFM-F= is compatible with select Cisco Nexus 3000 Series switches, such as the N3K-C3164Q-40GE or N3K-C3232C, which are commonly used in:
- Data Centers: Cooling switches managing high-speed spine-leaf architectures.
- Enterprise Networks: Ensuring reliability in environments with dense server racks.
- High-Temperature Environments: Mitigating thermal stress in industrial or outdoor deployments.
Addressing Core User Concerns
Q: Is this fan module compatible with all Nexus 3000 switches?
A: No. The CN3K-FAN30CFM-F= is designed for specific Nexus 3000 models. Always verify compatibility using Cisco’s Hardware Compatibility Tool or consult itmall.sale for guidance.
Q: Can I mix different CFM-rated fans in the same chassis?
A: Cisco recommends using identical fan modules to ensure uniform airflow and avoid thermal imbalances.
Q: How do I troubleshoot a failing fan module?
A: Most Nexus switches provide real-time alerts via CLI or SNMP. Replace the faulty unit promptly to prevent overheating.
Final Perspective
The CN3K-FAN30CFM-F= may seem like a minor component, but its role in maintaining switch longevity and performance cannot be overstated. In an era where uptime is synonymous with revenue, investing in reliable cooling solutions is non-negotiable. While third-party alternatives might offer cost savings, the risk of incompatibility or premature failure makes genuine Cisco modules the safer choice for mission-critical infrastructure. For network engineers, this fan isn’t just a part—it’s insurance against costly thermal shutdowns.
