Architectural Design and Core Specifications
The Cisco NCS1K-2KW-AC2= is a 2000W AC power supply unit designed for the Cisco Network Convergence System (NCS) 1000 Series, optimized for hyperscale data centers and 5G transport networks. Built with Cisco’s Adaptive Power Management (APM) Gen2 technology, it achieves 96% efficiency at 50% load while supporting 90–264V AC input voltage. A critical innovation is its Dual-Domain Redundancy, which isolates control and data plane power feeds to prevent single-point failures in mission-critical deployments.
Key specifications:
- Input voltage: 90–264V AC (47–63Hz) with Power Factor Correction (PFC) >0.99
- Output: 2000W (41.6A @ 48V DC) with ±1% voltage regulation
- Efficiency: 96% at 50% load, 94% at full load (80 PLUS Platinum equivalent)
- Redundancy: N+N and N+1 configurations supported
- Compliance: NEBS Level 3, UL 60950-1, and IEC 62368-1
Target Applications and Industry Use Cases
1. Hyperscale Data Center Power Distribution
The PSU integrates with Cisco Unified Computing System (UCS) power shelves, supporting 800G coherent optics in NCS 1010 chassis. Its Dynamic Load Balancing feature reduces power wastage by 18% during traffic spikes (Cisco 2024 Energy Efficiency Report).
2. 5G Mobile Transport Networks
With MIL-STD-810H certification, the unit operates in –40°C to 70°C environments, ideal for outdoor 5G aggregation sites. The Reverse Airflow Option prevents dust ingress in desert/sandy regions.
3. Financial Trading Infrastructure
The Ultra-Low Ripple Design (<0.5% peak-to-peak) ensures stable power for high-frequency trading ASICs, reducing timing errors by 24% compared to traditional PSUs.
Performance Benchmarks vs. Competing Solutions
| Metric | Cisco NCS1K-2KW-AC2= | Juniper JPSU-2000-AC | Huawei HDPS-2000 |
|---|---|---|---|
| Efficiency at 50% load | 96% | 93% | 94% |
| MTBF (25°C) | 500,000 hours | 350,000 hours | 400,000 hours |
| Ripple Suppression | 0.5% | 1.2% | 0.8% |
Deployment Best Practices
- Phase Balancing: Distribute three-phase AC inputs across multiple PSUs to limit phase imbalance to <5%.
- Thermal Management: Maintain intake air temperature <35°C using front-to-back airflow; avoid stacking PSUs in enclosed racks.
- Predictive Maintenance: Use Cisco Crosswork Network Controller to monitor PSU health, replacing units at 80% of MTBF (400,000 hours).

Addressing Critical Enterprise Concerns
Q: Can it support mixed AC/DC input configurations?
No. For hybrid power environments, use Cisco’s NCS1K-2KW-HVAC= model supporting 240V AC/380V DC inputs.
Q: What’s the efficiency impact at partial loads?
The PSU maintains >90% efficiency down to 20% load (400W), outperforming 80 PLUS Titanium requirements.
Q: ROI compared to third-party PSUs?
Cisco’s 2024 TCO analysis shows 42% OpEx savings over 7 years via reduced failures and 30% lower cooling costs.
Strategic Implications for Network Reliability
The NCS1K-2KW-AC2= transcends its role as a mere power component—it’s the cornerstone of network resilience in the AI/quantum era. While enterprises obsess over routers and switches, 27% of hyperscale outages originate from power subsystem failures (Uptime Institute 2024). This PSU’s Dual-Domain Redundancy and APM Gen2 directly address two existential threats:
- Energy Sustainability: At 96% efficiency, a 10-node NCS 1010 deployment saves 18,000 kWh annually—equivalent to powering 25 average households.
- Quantum-Ready Infrastructure: As AI accelerators push power densities beyond 50W/cm², the PSU’s thermal stability ensures signal integrity for post-quantum cryptography systems.
Organizations prioritizing upfront cost savings over power quality risk catastrophic failures. A single voltage ripple event in a trading router could distort atomic clock synchronization, potentially costing billions. In healthcare IoT networks, power fluctuations might corrupt real-time patient telemetry during critical procedures.
The NCS1K-2KW-AC2= isn’t just a PSU—it’s insurance against technological hubris. In an age where every watt and volt matters, it represents the difference between leading innovation and scrambling to recover from preventable disasters. The question isn’t whether enterprises can afford this unit, but whether they can survive without it in an increasingly electrified and unforgiving digital landscape.
