In a multinational financial services firm, IT operations replaced failing stock Cisco Catalyst 4500-X fans with the C4KX-FAN-R front-to-back cooling fan. The high-performance replacement restored proper airflow through densely populated switch racks, reduced server inlet temperatures by 12 °C, and eliminated unplanned network outages. Benefit: Enhanced thermal management yields 99.99 % uptime, prolongs hardware life, and lowers cooling energy costs.
A Tier 1 telecom provider deployed virtual network functions on Catalyst 4500-X aggregation switches in a regional POP. Integrating the C4KX-FAN-R front-to-back cooling fan maintained consistent rack air pressure under peak traffic loads. Outcome: Sustained throughput at 100 Gbps, zero thermal alarms over six months, and a 30 % reduction in field service dispatches. Benefit: Guaranteed network reliability and SLAs with minimized operational expenditure.
A global automotive manufacturer’s plant control network uses Catalyst 4500-X switches in non-conditioned enclosures on the shop floor. Installing C4KX-FAN-R fans ensured front-to-back airflow despite ambient heat of 45 °C. Result: Stable switch operation, no overheating events across 24/7 production shifts, and uninterrupted SCADA communications. Benefit: Prevented costly downtime, secured real-time control, and maintained production throughput.

The C4KX-FAN-R provides excellent cooling. It helps maintain the proper temperature in our network setup, improving efficiency.
The C4KX-FAN-R= is a replacement front-to-back airflow cooling fan designed for Cisco Catalyst 4500-X switches. It ensures optimal thermal management by drawing air through the front chassis and expelling it at the rear.
The C4KX-FAN-R= is fully compatible with Cisco Catalyst 4500-X series switches. It also fits any chassis requiring an identical 40 mm x 40 mm fan module with front-to-back airflow.
This fan module operates at 12 V DC, consumes up to 5 W, and delivers 15 CFM airflow at 45 dBA noise level. Its MTBF exceeds 100,000 hours for reliable, continuous operation.
Power down the switch, remove the defective fan module, then slide the C4KX-FAN-R= into the vacant slot until it clicks securely. Reapply power and verify fan status via the switch’s system health menu.
The C4KX-FAN-R= provides front-to-back airflow, drawing cool air from the switch’s front intake and expelling hot air out the rear. This direction aligns with Cisco’s recommended thermal design for Catalyst 4500-X.
At full speed, the C4KX-FAN-R= generates approximately 45 dBA of noise, comparable to a quiet office environment. Noise remains consistent under typical data center loads.
The C4KX-FAN-R= draws 12 V DC and consumes up to 5 W of power. This low power requirement minimizes impact on overall switch power budgets.
This fan uses a standardized 4-pin PWM connector for precise speed control and integration with the Catalyst 4500-X fan monitoring system. No additional wiring or adapters are required.
Yes, the C4KX-FAN-R= is an OEM Cisco replacement fan module certified for Cisco Catalyst 4500-X switches. It meets Cisco’s quality, performance, and reliability standards.
After powering down your switch, unplug the faulty fan module, align the C4KX-FAN-R= with the slot guide rails, and firmly insert it until it locks. Power on the switch and confirm normal fan operation through the system health interface.
Regularly clean front intake vents with a soft brush or canned air to prevent dust buildup. Inspect fan operation quarterly and replace the module if you observe decreased airflow or increased noise.
