​​CP-8800-A-KEM-3PC= Overview​​

The ​​CP-8800-A-KEM-3PC=​​ is a ​​3-Port AC Power Entry Module (KEM) Kit​​ designed for Cisco 8800 Series Aggregation Services Routers, including the ASR 8800. This module simplifies high-density power distribution while enabling scalable, redundant configurations for mission-critical network environments like telecom core networks or large-scale data centers.

​​Core Technical Specifications​​

• ​​Power Input​​: Three independent AC feeds (100–240V), each supporting up to 3.6kW.
• ​​Compatibility​​: Tailored for Cisco ASR 8800 chassis (e.g., ASR-8806, ASR-8812).
• ​​Redundancy​​: Supports ​​N+N power redundancy​​ for zero-downtime failover during outages.
• ​​Certification​​: Complies with global safety standards, including IEC 60950 and UL 60950-1.
• ​​Hot-Swappable​​: Integrated design allows replacement without shutting down the router.

​​Critical Advantages for High-Power Deployments​​

​​1. High-Density Power Distribution​​
By consolidating three AC inputs into one module, the CP-8800-A-KEM-3PC= eliminates the need for external power distribution units (PDUs). This reduces cable clutter and simplifies rack management.

​​2. Resilient Redundancy​​
The triple-feed design ensures continuous operation even if two power sources fail—ideal for environments requiring “five-nines” (99.999%) uptime, such as 5G core networks.

​​3. Scalability Without Rework​​
Additional KEMs can be added to the chassis as power demands grow, supporting future upgrades like 400G line cards or expanded service modules.

​​Addressing Key User Concerns​​

​​Q: Is this module compatible with DC power systems?​​
No. The CP-8800-A-KEM-3PC= is strictly designed for AC power inputs. For DC environments, Cisco offers separate DC KEM variants.

​​Q: How does it differ from the CP-8800-A-KEM-2PC= model?​​
The “3PC” provides ​​three AC feeds​​ versus the “2PC”’s dual feeds, enhancing redundancy and total power capacity for larger ASR 8800 chassis (e.g., ASR-8812).

​​Where to Source Authentic KEM Kits​​

To ensure compliance and avoid counterfeit risks, purchase CP-8800-A-KEM-3PC= units directly through itmall.sale’s Cisco inventory. Third-party sellers often lack validated thermal and safety testing.

​​Practical Perspective​​

The CP-8800-A-KEM-3PC= is more than a power module—it’s a foundational component for operators modernizing infrastructure to handle surging bandwidth demands. While its triple redundancy is overkill for smaller deployments, it’s indispensable in carriers and hyperscale data centers where downtime costs millions per minute. However, its complexity demands meticulous installation by certified engineers to avoid misconfiguration. For organizations eyeing long-term scalability, investing in this KEM upfront future-proofs the ASR 8800 chassis, but paired exclusively with genuine components to avoid voiding support agreements.
