G1116-2000WNA – 2000W CRPS Power Supply for Telecom Power Shelves, Carrier-Grade Networking, and High-Density Edge Platforms
The G1116-2000WNA 2000W CRPS power supply is built for carrier-grade telecom shelves, high-density network appliances, and edge computing platforms that demand reliable high-voltage output in compact deployments. Its 1U CRPS-standard footprint (185 × 73.5 × 40 mm) ensures efficient integration in systems where space and airflow are tightly managed. Delivering a main output of 54.5V at 36.7A with a 12V standby rail, it supports power-hungry PoE architectures, distributed networking nodes, and advanced control boards. The input range of 90–264Vac / 180–300Vdc enables seamless use across global AC grids and DC telecom infrastructures, making it suitable for cross-region rollouts. Digital power management via PMBus 1.2 provides real-time telemetry, event reporting, and precise parameter control, improving system reliability and maintenance visibility. Its high-efficiency design allows stable performance with reduced thermal load, especially under continuous heavy workloads. The unit’s intelligent fan control adapts cooling to real-time thermal conditions, helping maintain low acoustic levels while preserving component lifespan. Hot-swap capability ensures operational continuity, allowing field technicians to replace modules without interrupting service in mission-critical environments.

Deployment Scenarios
The G1116-2000WNA represents the peak output tier of the G1116 family, providing 2000W continuous capacity for infrastructures that operate under constant high utilization and require stable delivery across CPU/GPU mixed environments. This power class is suited for HPC clusters, large virtualization stacks, multi-accelerator edge nodes, heavy NVMe arrays, inference gateway racks, and enterprise compute farms where performance retention under simultaneous tasks is mandatory. Compared to 1600W, the 2000W tier supports denser accelerator populations, more concurrent VM scheduling, and higher I/O duty cycles, sustaining throughput during rebuild windows, traffic bursts or AI-forward workloads without rail fluctuation.

Power Architecture & Reliability Design
The G1116-2000WNA employs a reinforced power conversion structure optimized for continuous heavy-throughput operation, supporting multi-GPU acceleration, AI inference pipelines, and high-frequency I/O processing. Its electrical design maintains stable voltage behavior even as load fluctuates across virtual machine farms, storage fabrics, and accelerator workloads, allowing systems to operate near peak utilization without rail degradation.
Ripple suppression and EMI filtering protect PCIe lanes and high-speed network links during intensive commit activity, synchronized rebuilds, and data-heavy execution phases. This controlled electrical response minimizes interference and performance jitter when multiple subsystems draw power concurrently, making the unit well suited for dense compute environments with sustained concurrency.
Thermal pathing is engineered to distribute heat evenly during extended high-duty cycles, helping prevent gradual performance decay and component stress over time. PMBus visualization provides operators with insight into fan curve evolution, thermal signatures, and load response patterns, enabling informed capacity planning and predictive maintenance across large fleets. As the top-tier option within the G1116 platform, the G1116-2000WNA is designed for 24/7 enterprise and HPC-class deployments that demand long-term stability, scalability, and operational predictability.
