What Design Innovations Define the DS-C96S-FAN-E=?
The Cisco DS-C96S-FAN-E= serves as a hot-swappable modular fan tray engineered for Cisco’s 96-port Nexus 9500 series switches, addressing critical cooling demands in hyperscale data centers. Utilizing dual counter-rotating fan arrays, it achieves 27% higher airflow density than previous N9K-C9500-FAN models while maintaining 45 dB(A) noise levels at full load. Its N+1 redundancy architecture enables single fan failure tolerance without throughput degradation, crucial for five-nines (99.999%) availability requirements. The tray integrates real-time thermal telemetry sensors that dynamically adjust RPMs based on ASIC temperatures, reducing energy consumption by 18% compared to fixed-speed predecessors.
Performance Comparison: DS-C96S-FAN-E= vs Legacy Cisco Cooling Systems
- Airflow Capacity: 240 CFM vs 195 CFM in N9K-C9500-FAN2
- Power Efficiency: 94% Platinum-rated PSU compatibility vs Gold-certified predecessors
- Maintenance Interval: 50,000-hour MTBF (2.8x N9K-C93180YC-FX3 fan modules)
- Acoustic Profile: 45 dB(A) at 40°C ambient vs 52 dB(A) in MDS 9396V cooling systems
| Feature | DS-C96S-FAN-E= | N9K-C9500-FAN2 (2019 Model) |
|---|---|---|
| Max Airflow | 240 CFM | 195 CFM |
| Redundancy Support | N+1 | N |
| Thermal Sensors | 12-channel telemetry | 4-channel monitoring |
| Energy Consumption | 480W peak | 620W peak |
Where to Source Certified DS-C96S-FAN-E= Units?
For guaranteed compatibility with Cisco’s Nexus 9500 chassis, ITMALL’s Cisco Store provides:
- Factory-new modules with Cisco Smart Net 24/7 priority replacement
- Pre-configured airflow kits for mixed east-west and front-back cooling architectures
- Cisco-validated thermal gaskets ensuring optimal seal in 45U rack deployments
The DS-C96S-FAN-E= resolves ASIC thermal throttling issues prevalent in 32G/64G FC switch fabrics through predictive airflow algorithms that pre-cool adjacent line cards. While third-party cooling solutions exist, only Cisco-certified configurations fully support cross-fabric thermal synchronization and In-Service Field Replacement (ISFR) protocols. Its tool-less installation design outperforms Arista’s comparable modules in mixed 25G/100G environments, particularly when maintaining sub-3°C temperature differentials across 96-port configurations. For enterprises prioritizing adaptive cooling scalability alongside TCO reduction, this fan module sets new benchmarks in data center infrastructure resilience.
