Overview of the CP-8841-3PW-NA-K9=

The ​​Cisco CP-8841-3PW-NA-K9=​​ is a 3000W, 3-phase AC power supply engineered for Cisco Catalyst 8800 Series switches deployed in industrial and enterprise environments. Designed specifically for North American power grids, it ensures stable operation in high-demand scenarios like manufacturing plants, utilities, or data centers.


Technical Specifications and Regional Compatibility

  • ​Input Voltage​​: ​​200–240 VAC​​ (3-phase), optimized for North American industrial power standards.
  • ​Output Power​​: ​​3000W​​ with 90% efficiency, reducing energy costs in 24/7 operational settings.
  • ​Compatibility​​: Exclusively supports Cisco Catalyst 8800 Series switches, including the C8800-32X and C8800-48X models.
  • ​Environmental Ratings​​: Operates in temperatures from ​​-40°C to 70°C​​, ideal for harsh industrial environments.
  • ​Certifications​​: UL 60950-1, CSA, and RoHS compliant, meeting North American safety and environmental regulations.

Key Advantages Over Single-Phase Power Supplies

​Higher Efficiency in Industrial Loads​​: 3-phase power distribution minimizes energy loss compared to single-phase units, lowering operational costs for high-density deployments.

​Resilience to Voltage Fluctuations​​: Built-in surge protection and wide input voltage tolerance guard against unstable industrial power grids.

​Redundancy for Mission-Critical Uptime​​: Supports ​​N+1 configurations​​, allowing seamless failover during power supply failures or maintenance.


Addressing Common Deployment Questions

​Q: Can the CP-8841-3PW-NA-K9= power non-industrial Cisco switches?​
Yes, but only if the switch is part of the Catalyst 8800 Series. Non-industrial variants (e.g., C8800-12X) still benefit from its rugged design.

​Q: How does it compare to the CP-8832-3PC-EU-K9= model?​
While both are 3-phase, the CP-8841-3PW-NA-K9= is tailored for North America’s 200–240V grids, whereas the EU-K9 variant aligns with European 380–415V standards.

​Q: Is external cooling required?​
No. The module includes integrated, variable-speed fans that adjust to thermal loads. Ensure chassis airflow aligns with Cisco’s guidelines for optimal performance.


Sourcing Authentic CP-8841-3PW-NA-K9= Modules

For guaranteed compatibility and warranty coverage, purchase from authorized partners like [“CP-8841-3PW-NA-K9=” link to (https://itmall.sale/product-category/cisco/). Third-party sellers often lack Cisco’s quality assurance, risking counterfeit components.


Final Insight on Power Infrastructure Design

The CP-8841-3PW-NA-K9= fills a critical gap in North American industrial networking, where unstable power and extreme conditions threaten uptime. While its upfront cost is higher than standard data center power supplies, its durability and efficiency justify the investment for industries like energy or logistics. For IT teams managing Catalyst 8800 deployments, this module isn’t just a component—it’s insurance against costly downtime.
