​​What Is the CP-8851-3PW-NA-K9=?​​

The ​​CP-8851-3PW-NA-K9=​​ is a ​​three-phase AC power supply module​​ designed for Cisco’s 8800 Series chassis, including the Catalyst 8800 and ASR 8800 platforms. It addresses the growing power demands of modern networks by delivering ​​high-efficiency, scalable power redundancy​​ in environments where uptime and energy cost management are critical. Unlike single-phase modules, it supports ​​three-phase power input​​, reducing current load per phase and improving energy distribution efficiency.

​​Key Technical Specifications​​

• ​​Compatibility​​: Exclusive to Cisco 8800 Series chassis (Catalyst 8800, ASR 8800).
• ​​Power Capacity​​: ​​3000W output​​ with three-phase AC input (200–240V).
• ​​Redundancy​​: Supports ​​N+1 redundancy​​ configurations for fault tolerance.
• ​​Efficiency Rating​​: ​​90%+ efficiency​​ under typical loads, minimizing operational costs.
• ​​Hot-Swap Capability​​: Replace or upgrade without powering down the chassis.

​​Primary Use Cases​​

1. ​​High-Density Data Centers​​

Three-phase power is standard in data centers, and this module’s ​​efficient load distribution​​ aligns with the infrastructure, reducing overheating risks and energy waste.

2. ​​Large Enterprise Networks​​

Organizations with campus-wide deployments use it to power ​​bandwidth-intensive applications​​ like video surveillance, AI-driven analytics, and UCaaS platforms.

​​Addressing Critical User Questions​​

​​Q: Can this module operate in regions with single-phase power infrastructure?​​
A: No. The ​​CP-8851-3PW-NA-K9=​​ requires a three-phase power source. For single-phase setups, consider alternatives like the CP-8851-ACPI.

​​Q: How does it compare to the CP-8851-3PNR-K9= model?​​
A: The 3PNR variant includes ​​additional redundancy features​​ (N+N support), whereas the 3PW focuses on ​​three-phase efficiency​​. Choose based on your redundancy needs and facility power design.

​​Where to Source Reliable Modules​​

For guaranteed compatibility and warranty coverage, purchase the CP-8851-3PW-NA-K9= from “CP-8851-3PW-NA-K9=” link to (https://itmall.sale/product-category/cisco/). Third-party sellers often lack Cisco’s firmware validation, risking performance issues.

​​The Long-Term Value of Three-Phase Power​​

In my experience, enterprises transitioning to three-phase power often overlook its ​​cumulative cost savings​​. The ​​CP-8851-3PW-NA-K9=​​ not only future-proofs power infrastructure but also reduces cooling costs through higher efficiency. While retrofitting facilities for three-phase input can be costly upfront, the ROI becomes evident within 2–3 years for high-utilization networks. Always partner with certified suppliers to avoid compatibility pitfalls that negate these benefits.
