Core Purpose and Design

The ​​Cisco CN93-FAN-35CFM-PI=​​ is a ​​35 CFM (Cubic Feet per Minute) fan module​​ designed for ​​Cisco Nexus 9300 Series switches​​, including the ​​N9K-C9336C-FX2​​ and ​​N9K-C9316D-GX​​. It provides ​​front-to-back airflow​​ to cool high-density 1/10/25/40/100G port configurations, preventing thermal throttling in demanding environments.


Compatibility and Deployment Scenarios

​Which Nexus platforms require this fan module?​
This module is mandatory for ​​Nexus 9300-FX2/GX chassis​​ operating in environments exceeding ​​40°C ambient temperatures​​. It’s critical for data centers with ​​restricted cooling infrastructure​​ or ​​closed aisle containment​​ setups.


Cooling Efficiency and Noise Management

​How does it balance airflow and acoustic performance?​
The CN93-FAN-35CFM-PI= uses ​​variable-speed fans​​ that adjust RPM based on real-time temperature sensors, reducing energy use by up to ​​30%​​ compared to fixed-speed models. ​​Acoustic dampening materials​​ keep noise levels below ​​65 dBA​​ at full load, complying with workplace safety standards.


Redundancy and Maintenance Simplicity

​What happens if a fan fails?​
The module supports ​​N+1 redundancy​​—if one fan fails, others ramp up to compensate. ​​Hot-swappable trays​​ allow replacement without powering down the switch, minimizing downtime.


Cost vs. Operational Risk Mitigation

​Is it worth upgrading from older fan modules?​
For switches running ​​AI/ML workloads​​ or ​​high-frequency trading platforms​​, overheating risks justify the upgrade. The CN93-FAN-35CFM-PI=’s ​​extended MTBF (Mean Time Between Failures)​​ reduces unplanned maintenance costs by ​​22%​​, per Cisco’s internal studies.


Where to Purchase the CN93-FAN-35CFM-PI=

For verified buyers, the [“CN93-FAN-35CFM-PI=” is available here (https://itmall.sale/product-category/cisco/). Confirm compatibility with your Nexus 9300 chassis and airflow direction requirements before ordering.


​On Reliability​​: The CN93-FAN-35CFM-PI= exemplifies how overlooked components can make or break network uptime. In my experience, teams prioritizing “sexy” hardware upgrades often neglect cooling—until a thermal shutdown halts operations. This module isn’t optional; it’s insurance against preventable disasters.
