CP-8811-A-K9=: How Does It Power Cisco 8800 Series Routers for High-Availability Networks?

​​Understanding the CP-8811-A-K9=​​

The ​​CP-8811-A-K9=​​ is a ​​3.6kW AC Power Supply Module​​ engineered for Cisco ASR 8800 Series Aggregation Services Routers. Designed for environments demanding uninterrupted uptime, such as telecom core networks or hyperscale data centers, this module ensures reliable power delivery and redundancy for high-density routing operations.

​​Technical Specifications​​

• ​​Power Output​​: 3600W (3.6kW) with 100–240V AC input, auto-sensing voltage.
• ​​Compatibility​​: Exclusively supports Cisco ASR 8800 chassis (e.g., ASR-8806, ASR-8812).
• ​​Redundancy​​: Enables ​​N+1 or N+N configurations​​ to eliminate single points of failure.
• ​​Efficiency​​: 80 PLUS Platinum certified, achieving up to 94% efficiency.
• ​​Hot-Swappable​​: Replace or upgrade without disrupting router functionality.

​​Key Benefits for Mission-Critical Deployments​​

​​1. High-Power Density​​
The 3.6kW output supports energy-intensive modules like 400G line cards, ensuring seamless performance for bandwidth-heavy applications such as video streaming or AI-driven analytics.

​​2. Adaptive Load Management​​
Intelligent power allocation prioritizes active modules during peak loads, preventing overloads and optimizing energy use.

​​3. Global Compliance​​
Certified for use in multiple regions, this module adheres to strict electrical safety standards, including UL and CE.

​​Addressing Common User Questions​​

​​Q: Can this power supply be used in Cisco ASR 9000 routers?​​
No. The CP-8811-A-K9= is designed solely for the ASR 8800 Series. ASR 9000 routers require distinct power modules.

​​Q: How does it compare to the CP-8800-A-KEM-3PC= KEM kit?​​
The CP-8811-A-K9= is a ​​dedicated power supply​​, while the KEM kit manages power distribution. They complement each other in full redundancy setups.

​​Sourcing Authentic Modules​​

For guaranteed performance and warranty coverage, purchase the CP-8811-A-K9= through itmall.sale’s Cisco listings. Counterfeit units often lack critical safety certifications, risking hardware failure.

​​Operational Insight​​

The CP-8811-A-K9= is a linchpin for operators scaling ASR 8800 deployments to handle surging traffic. While its 3.6kW capacity is overkill for small nodes, it’s indispensable in core sites where power redundancy directly impacts revenue and reliability. However, integrating it requires meticulous planning—pairing it with undersized cooling systems or incompatible line cards can negate its benefits. For enterprises prioritizing future-ready infrastructure, this module is a strategic buy, but only when sourced through authorized channels to avoid costly compatibility pitfalls.
