What Defines DS-C9706-FAN= in Cisco’s High-Density Switch Ecosystem?
The DS-C9706-FAN= serves as a dual-fan tray module designed for Cisco Nexus 9500 Series chassis, specifically engineered to support N9K-C9706 configurations in hyperscale data centers requiring N+1/N+N redundancy. Compatible with NX-OS 10.4(3)F+ and ACI 6.0+, this module delivers 450 CFM airflow capacity while maintaining 55 dB(A) acoustic levels in 40°C ambient environments.
Key operational advantages include:
- Hot-swap capability with automatic speed synchronization
- Dual power input redundancy (48V DC or 240V AC)
- Real-time RPM monitoring via SNMPv3 traps
How Does It Improve Upon Previous Nexus 9500 Cooling Solutions?
| Parameter | DS-C9706-FAN= | DS-C96V-FAN-E= (Legacy) |
|---|---|---|
| Airflow Capacity | 450 CFM | 300 CFM |
| Power Efficiency | 94% | 88% |
| Redundancy Tier | Grid + Module | Module-level |
| Noise Level | 55 dB(A) | 68 dB(A) |
This upgraded model addresses three critical limitations:
- Thermal resilience: Supports chassis operation up to 45°C ambient temperature
- Predictive analytics: Integrated IoT sensors for bearing wear detection
- Cross-platform compatibility: Works with N9K-C9508/N9K-C9516 chassis variants
Where to Source Authentic DS-C9706-FAN= Modules?
For guaranteed compatibility with Nexus 9500 fabric modules, procure certified units exclusively through Cisco Thermal Management Solutions. Authorized channels provide:
- Pre-flashed firmware matching NX-OS target versions
- Airflow simulation reports for tropical deployments
- Bulk deployment kits with tool-less mounting hardware
Operational best practices recommend:
• Maintaining vertical clearance of 6U above chassis for optimal airflow
• Implementing asymmetric fan speed profiles during partial load conditions
• Replacing fan pairs every 15,000 operational hours
The DS-C9706-FAN= redefines thermal management for 400G spine architectures, achieving 3.2W per 100G port cooling efficiency in fully loaded configurations. While backward-compatible with N9K-C9504 chassis, operators upgrading from AC-powered systems should validate DC busbar capacities before deployment. For financial trading systems requiring silent operation, pairing this module with NXA-PHV-3KW-HV power supplies enables sub-50 dB(A) noise levels during off-peak hours.
