What Is the C8500-FAN-3R=? Redundancy, Compatibility, and Performance Explained

Overview of the C8500-FAN-3R=

The ​​C8500-FAN-3R=​​ is a ​​hot-swappable, redundant fan module​​ designed for Cisco Catalyst 8500 Series platforms. It ensures optimal thermal management for high-performance routing and security operations in enterprise or data center environments.

Key Technical Specifications

• ​​Redundancy​​: Supports ​​N+1 fan redundancy​​, minimizing downtime if a single fan fails.
• ​​Airflow​​: Front-to-back cooling with ​​variable speed control​​ to adapt to temperature changes.
• ​​Compatibility​​: Exclusively built for Catalyst 8500 chassis like the C8500-12X4QC and C8500-20X6C.
• ​​Noise Levels​​: Operates at ​​≤45 dB​​ under typical loads, suitable for office deployments.

Addressing Common User Questions

​​Q: Can the C8500-FAN-3R= be used in older Catalyst models?​​
A: No. This module is ​​only compatible with the Catalyst 8500 Series​​ due to its unique airflow design and power requirements.

​​Q: How does redundancy work in practice?​​
A: The ​​3+1 modular design​​ allows one fan to fail without impacting system performance. Alerts are triggered via Cisco IOS-XE for proactive replacement.

​​Q: Is installation possible without shutting down the chassis?​​
A: Yes. The ​​hot-swappable feature​​ enables replacement or addition of fans while the system is operational.

Ideal Deployment Scenarios

• ​​High-density data centers​​: Maintains cooling efficiency for power-hungry services like SD-WAN or encrypted traffic analysis.
• ​​24/7 enterprise networks​​: Redundancy ensures uninterrupted operations for critical applications.
• ​​Edge computing setups​​: Compact design suits environments with space constraints.
