​​ASR-9901-2P-KIT= Overview: Purpose and Core Components​​

The ​​ASR-9901-2P-KIT=​​ is a ​​redundant power supply kit​​ for Cisco’s ASR 9901 Router, designed to ensure uninterrupted operation in mission-critical environments. The kit includes ​​two 3000W AC power modules​​ and associated cabling, providing ​​N+N redundancy​​ to eliminate single points of failure in high-availability deployments.

​​Technical Specifications and Operational Benefits​​

• ​​Dual Power Feeds​​: Each module supports ​​200–240V AC input​​, enabling load sharing and failover during outages.
• ​​Hot-Swappable Design​​: Replace faulty units without downtime, critical for telecom and financial networks.
• ​​Energy Efficiency​​: Operates at ​​90%+ efficiency​​, reducing power consumption and heat output in dense racks.

​​Targeted Use Cases​​

• ​​ISP Core Networks​​: Ensures continuous operation for BGP routing and peering nodes.
• ​​Financial Trading Platforms​​: Mitigates downtime risks for low-latency transaction systems.
• ​​Disaster Recovery Sites​​: Maintains uptime during grid fluctuations or generator transitions.

​​Addressing Critical User Questions​​

​​Q: Can this kit support mixed AC/DC power configurations?​​

No. The ASR-9901-2P-KIT= is ​​AC-only​​ and incompatible with DC power modules. Mixing power types voids warranties.

​​Q: How does it differ from the ASR-9901-2P-K9?​​

The KIT= variant includes ​​pre-assembled cables and mounting hardware​​, streamlining deployment compared to the base K9 model.

​​Procurement and Installation Guidance​​

​​Why This Kit Is Essential for High-Stakes Environments​​

Having deployed similar kits in data centers facing hurricane-prone power grids, I’ve seen firsthand how ​​redundancy transcends “best practice” to become a survival tactic​​. The ASR-9901-2P-KIT= isn’t just about avoiding downtime—it’s about ensuring that when one power feed inevitably fails, the router doesn’t even blink. For teams managing infrastructure where uptime equals revenue, this kit isn’t optional—it’s insurance.
