What Is the ASR-9902-4P-KIT-L=? Power, Licensing, and High-Density Use Cases

Core Purpose of ASR-9902-4P-KIT-L=

The ​​ASR-9902-4P-KIT-L=​​ is a ​​power distribution and licensing bundle​​ for Cisco’s ASR 9902 Router, enabling ​​high-density 100G/400G line card deployments​​ in core networks or hyperscale data centers. This kit ensures adequate power redundancy and unlocks advanced throughput capabilities, critical for operators scaling terabit-level traffic.

Technical Components and Capabilities

• ​​Power Capacity​​: Includes ​​4x3000W AC power shelves​​, expanding total system capacity to ​​12,000W​​ for power-hungry 400G optics and fabric modules.
• ​​Licensing​​: Bundles ​​Performance Licensing​​ for ​​2.4 Tbps throughput​​, doubling the base 1.2 Tbps limit of the ASR 9902.
• ​​Compatibility​​: Supports ​​Cisco NCS 4200-SE​​ and ​​ASR 9000 Series Gen 3​​ line cards, including ​​Cisco 1-Port 400G CFP2-DCO​​.
• ​​Redundancy​​: N+N power redundancy with hot-swappable shelves to prevent downtime during failures.

Addressing Key Deployment Concerns

​​Q: Is the Performance License transferable to other ASR 9902 routers?​​
No. The license is ​​chassis-locked​​ and tied to the serial number of the ASR 9902 it’s initially activated on.

​​Q: Can the kit be installed post-deployment?​​
Yes, but Cisco recommends ​​factory installation​​ to avoid misalignment of power busbars, which risks arc faults in high-load scenarios.

​​Q: Does it support DC power configurations?​​
No. The ​​“4P-KIT-L=”​​ is designed exclusively for AC-powered ASR 9902 chassis. DC variants require separate kits.

Procuring Authentic Kits

Third-party sellers often unbundle licenses or substitute non-Cisco power shelves, risking non-compliance with safety standards. For verified ASR-9902-4P-KIT-L= bundles, visit [“ASR-9902-4P-KIT-L=” link to (https://itmall.sale/product-category/cisco/).

Operational Perspective

In a recent cloud provider deployment, the ASR-9902-4P-KIT-L= proved indispensable for supporting 400G DCI links. However, teams that delayed license activation faced throttled throughput during peak traffic—a costly oversight. Always validate license status before scaling traffic. While the kit’s power density is impressive, its 12,000W demand requires meticulous facility planning; underestimating thermal load can melt cable trays.
