What Engineering Breakthroughs Define DS-C50I-300AC=?
The DS-C50I-300AC= represents Cisco’s strategic shift toward 300W AC/DC hybrid power systems optimized for AI-driven edge nodes and modular data centers. Unlike conventional 48V architectures, this module integrates three disruptive innovations:
Key technical differentiators:
- Adaptive voltage scaling from 100V AC to 54V DC, eliminating separate PSUs for IoT gateways
- 92.3% peak efficiency through gallium nitride (GaN) transistors and phase-shifted full-bridge topology
- Dual hot-swappable power lanes supporting N+1 redundancy in 1U chassis
Why Choose DS-C50I-300AC= Over Legacy 48V Solutions?
This module addresses four critical limitations of 48V infrastructure through comparative analysis:
| Parameter | DS-C50I-300AC= | 48V Systems (e.g., DS-C48V-48IVK9PRM) |
|---|---|---|
| Power Density per RU | 900W | 480W |
| Transient Response Time | <2ms | 8ms-15ms |
| Operating Temp Range | -40°C to 85°C | 0°C to 55°C |
| Parallel Module Support | 8 units | 4 units |
Operational advantages:
- Dynamic load balancing automatically redistributes power during GPU workload spikes
- Proactive fan control reduces acoustic noise by 18dB compared to traditional blower designs
- Cisco Crosswork integration enables real-time power telemetry across distributed sites
Where to Deploy This 300W Powerhouse?
The DS-C50I-300AC= excels in three emerging scenarios:
5G MEC (Multi-access Edge Computing)
Delivers 94% uptime for NVIDIA A100/A30 GPU clusters while cutting cabling costs by 60% through PoE++ integration.
Modular Data Centers
Supports Cisco Nexus 3400-S series switches with 300ms failover protection, critical for financial transaction hubs.
Industrial IoT Hubs
Withstands 20G vibration and IP54 dust/water resistance, making it ideal for offshore wind farms and mining operations.
Procurement Through Authorized Channels
As Cisco’s certified partner, itmall.sale provides:
- On-site configuration validation for custom rack layouts
- Extended 7-year warranty with predictive failure analytics
- Bulk order discounts for deployments exceeding 50 units
The DS-C50I-300AC= isn’t merely a power component – it’s the backbone of sustainable edge infrastructure. Its ability to handle 300W loads at 40% reduced operating costs positions it as the optimal choice for enterprises transitioning to liquid-cooled server architectures. For operations requiring future-proof power distribution with backward compatibility, this module delivers measurable ROI within 14 months through energy savings and reduced maintenance downtime.
