Core Functionality and Design Purpose

The ​​Cisco C8300-RM-19-2R=​​ is a ​​rack-mount redundant power supply module​​ designed for the Cisco 8300 Series routers. It provides ​​N+N power redundancy​​ in mission-critical environments like data centers, industrial sites, and telecom edge networks, where uninterrupted operation is non-negotiable.

Technical Specifications and Key Innovations

Power Delivery and Efficiency

• ​​Dual 1100W AC power inputs​​: Delivers ​​2,200W total output​​ with 94% efficiency (80 Plus Platinum certified).
• ​​Hot-swappable design​​: Allows replacement without shutting down the router, critical for 24/7 operations.
• ​​Wide voltage range​​: Operates at 100–240V AC, compatible with global power standards.

Environmental and Operational Resilience

• ​​Operating temperature​​: -40°C to 70°C (-40°F to 158°F)
• ​​MIL-STD-810G compliance​​: Withstands vibrations up to 5Grms and shocks common in industrial or mobile deployments.

Key Deployment Scenarios

Data Center Edge Routing

Ensures continuous uptime for ​​Cisco SD-WAN vEdge​​ instances, preventing service disruptions during power grid fluctuations.

Telecom 5G Aggregation Sites

Supports ​​Multi-Access Edge Computing (MEC)​​ nodes, where power redundancy minimizes latency spikes in real-time applications like autonomous vehicle communications.

Offshore Energy Operations

Powers Cisco 8300 routers in oil rigs, surviving salt fog and humidity while maintaining encrypted SCADA data pipelines.

Addressing Critical User Concerns

How does it integrate with existing Cisco 8300 chassis?

The module slides into the ​​rear slot of C8300-1N1S-4T2X= or C8300-2N2S-6T= routers​​, auto-synchronizing with the primary power supply via ​​Cisco PowerSync technology​​.

What happens during a power supply failure?

The system seamlessly switches to the redundant unit within ​​<10ms​​, ensuring no packet loss for sensitive workloads like VoIP or real-time analytics.

Is it compatible with DC power sources?

No—this model is AC-only. For DC environments, consider the ​​C8300-RM-19-2R-DC=​​ variant.

• ​​Lead time​​: 3–5 weeks for standalone units
• ​​Warranty​​: 5-year hardware replacement with optional 24/7 critical support

Strategic Value Assessment

In sectors where downtime costs exceed $10k per minute, the C8300-RM-19-2R= isn’t just a component—it’s insurance. While its price point may deter smaller deployments, enterprises managing hyperscale IoT or financial trading networks will find its redundancy features indispensable. The true ROI materializes not during normal operations, but in those critical seconds when every millisecond of uptime counts.
