Core Specifications & Compatibility

The ​​C9400-PWR-2100AC=​​ is a ​​2100W AC power supply​​ designed for Cisco’s Catalyst 9400 Series modular chassis. It delivers ​​high-efficiency power​​ to support energy-intensive modules like the ​​C9400-LC-48HX++=​​ or ​​C9400-LC-48T++=​​, which require substantial PoE++ budgets for Wi-Fi 7 APs, IoT devices, and AV systems. Compatible with ​​Catalyst 9407R, 9410R, and 9436R chassis​​, this PSU ensures seamless scalability for high-density deployments.

Redundancy & Reliability Features

Engineered for ​​N+1 redundancy​​, the power supply supports hot-swappable operation, minimizing downtime during maintenance or failures. Its ​​front-to-back airflow​​ aligns with standard data center cooling configurations, maintaining optimal thermal performance even at ​​45°C ambient temperatures​​.

Efficiency & Power Management

With ​​80 Plus Platinum efficiency​​, the PSU achieves ​​≥94% energy conversion​​ at 50% load, reducing operational costs and heat output. Integrated ​​Cisco EnergyWise​​ dynamically allocates power based on real-time demand, prioritizing PoE++ devices while minimizing waste.

Deployment Scenarios & Use Cases

• ​​High-density wireless campuses​​: Power 48-port MultiGig line cards driving Wi-Fi 7 APs with 90W PoE++.
• ​​Industrial IoT hubs​​: Sustain PoE++ for motor controllers, sensors, and edge compute nodes.
• ​​Converged AV/IT networks​​: Deliver consistent power to 4K video systems and collaboration endpoints.

Installation & Firmware Requirements

The PSU slots into any available bay in the Catalyst 9400 chassis, requiring ​​Cisco IOS XE 17.9.1+​​ for advanced power management features. Firmware updates ensure compatibility with newer line cards and optimize load balancing across multiple PSUs.
