CP-8811-NC-K9=: What Makes It Essential for Cisco ASR 8800 Series Power Redundancy?

​​CP-8811-NC-K9= Overview​​

The ​​CP-8811-NC-K9=​​ is a ​​3.6kW AC Power Supply Module​​ designed for Cisco ASR 8800 Series Aggregation Services Routers. Tailored for high-availability networks, this module ensures stable power delivery in environments like telecom cores or cloud data centers, where downtime is not an option.

​​Core Technical Specifications​​

• ​​Power Output​​: 3600W (3.6kW) with 100–240V AC input, auto-ranging voltage support.
• ​​Compatibility​​: Exclusively compatible with Cisco ASR 8800 chassis (e.g., ASR-8806, ASR-8812).
• ​​Redundancy​​: Supports ​​N+1 configurations​​, enabling failover during power supply failures.
• ​​Efficiency​​: Meets ​​80 PLUS Platinum standards​​, achieving up to 94% efficiency under typical loads.
• ​​Hot-Swappable​​: Allows replacement without interrupting router operations.

​​Key Advantages for Network Operators​​

​​1. High-Density Power Support​​
The 3.6kW output accommodates power-hungry modules like 400G line cards, ensuring seamless operation for bandwidth-intensive applications such as 5G backhaul or video-on-demand services.

​​2. Adaptive Power Allocation​​
Intelligent load balancing dynamically adjusts power distribution to active modules, preventing overloads and optimizing energy consumption during peak traffic.

​​3. Global Compliance​​
Certified for international safety standards (e.g., UL, CE), this module is suitable for deployment across diverse regions without compatibility concerns.

​​Addressing Critical User Questions​​

​​Q: Is the CP-8811-NC-K9= backward-compatible with older ASR 9000 routers?​​
No. This module is engineered specifically for the ASR 8800 Series. ASR 9000 routers require distinct power supplies.

​​Q: How does it differ from the CP-8811-A-K9= model?​​
The “NC” variant includes ​​enhanced thermal management​​ for high-temperature environments, whereas the “A-K9=” focuses on general-purpose deployments.

​​Sourcing Genuine Modules​​

To ensure compliance and avoid counterfeit risks, purchase the CP-8811-NC-K9= through itmall.sale’s verified Cisco inventory. Third-party sellers may supply non-certified units lacking critical safety features.

​​Deployment Insight​​

The CP-8811-NC-K9= is a cornerstone for ASR 8800 deployments in harsh or high-density environments. Its thermal resilience and Platinum efficiency make it ideal for operators prioritizing sustainability and uptime. However, its value diminishes if paired with incompatible line cards or inadequate cooling infrastructure. For enterprises scaling next-gen networks, this module is a strategic asset—but only when integrated as part of a holistic, vendor-validated solution. Cutting corners on authenticity or configuration could undermine its reliability, negating the very redundancy it promises.
