C4KX-FAN-R= Use Case
Enterprise Data Center Thermal Optimization with Catalyst 4500-X Fan Replacement
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.
Telecom Carrier NFV Infrastructure Reliability Enhancement
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.
Industrial Control Network Continuity in High-Heat Manufacturing
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.

Q
What is the C4KX-FAN-R= front to back cooling fan?
A
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.
Q
Which devices are compatible with the C4KX-FAN-R=?
A
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.
Q
What are the key technical specifications of the C4KX-FAN-R=?
A
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.
Q
How do I install the C4KX-FAN-R= on my Catalyst 4500-X switch?
A
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.
Q
What is the airflow direction of the C4KX-FAN-R=?
