Eaton Rack Power Module (RPM) — High-Density 36 kW Data Center Power Distribution

The Eaton Rack Power Module (RPM) is a purpose-built, high-density power distribution solution engineered to simplify data center power architecture. In a compact 3U footprint, the RPM delivers up to 36 kW of reliable, scalable power to backbone IT equipment, enablingData centers to maximize rack density without sacrificing electrical performance or uptime. By connecting directly from a three‑phase UPS (such as the Eaton BladeUPS) or an appropriate utility source, the RPM feeds secondary power distribution devices like the Eaton ePDU, creating a streamlined power path from utility to rack. With twelve pole positions, this modular approach provides organized, flexible distribution that supports efficient cable management and future growth, helping data centers optimize space and operational efficiency.

• High-density power distribution in a compact 3U cabinet: The RPM packs up to 36 kW of load capacity into a slim frame, enabling you to consolidate power infrastructure around critical servers, storage, and networking gear while preserving valuable rack space for IT assets. This density is ideal for modern hyper-converged deployments, dense blade architectures, and growing rack workloads where every inch of rack real estate matters.
• Flexible input options from UPS or utility sources: Designed for direct connection from a three-phase UPS (notably Eaton BladeUPS) or compatible utility feeds, the RPM minimizes intermediate components, reduces power conversion losses, and simplifies the overall power chain. This flexibility supports quick integration into existing power architectures and makes it easier to reconfigure layouts as capacity needs evolve.
• Scalable distribution topology with twelve pole positions: Twelve pole positions provide a structured, expandable path for distributing power to secondary devices such as ePDUs, PDUs, or other distribution modules. This arrangement supports phased deployment, load balancing across phases, and straightforward future expansion without disruptive rework to cabling or rack layouts.
• Reliability, protection, and proactive monitoring: The RPM incorporates robust protection features to guard against overcurrent, short circuits, and thermal events. Real-time status indicators and built-in monitoring enable proactive maintenance, quick fault isolation, and improved uptime for mission-critical workloads across the data center.
• Seamless Eaton ecosystem integration: Engineered to work hand-in-hand with Eaton’s power ecosystem—including BladeUPS, ePDU, and other power management components—the RPM supports centralized management, streamlined maintenance, and consistent performance reporting within a single, cohesive system.

How to Install Eaton Rack Power Module

Installing the Eaton RPM is a straightforward process when performed by qualified facility and IT personnel. Follow these high-level steps to ensure proper integration, safety, and optimal performance:

• Plan and verify requirements: Confirm load requirements, anticipated growth, and the input source (UPS or utility). Ensure you have adequate clearance, access, and rack space for a 3U RPM along with the connected secondary distribution devices.
• Prepare the rack and mounting: Slide the RPM into the appropriate 19-inch rack rails and secure it firmly using the included mounting hardware. Verify stability and ensure there is proper ventilation and clearance for intake and exhaust paths.
• Connect the input power: Establish the direct connection from the three-phase UPS (e.g., Eaton BladeUPS) or the chosen utility source to the RPM’s input terminals, following the manufacturer’s wiring diagram and local electrical codes. Ensure proper torque on conductors and secure termination points.
• Link to secondary distribution: Route and connect the RPM’s output to the secondary power distribution devices such as Eaton ePDU or other PDUs, maintaining orderly cabling with clear labeling for phase, load, and circuit identification.
• Configure protection and monitoring: Enable protective features, configure alarms or thresholds as recommended, and set up any remote monitoring interfaces. Verify communications with centralized management tools and confirm that status indicators reflect healthy operation.
• Commission and validate: Power up the RPM, perform a light-load check, and verify that all connected devices receive clean, stable power. Conduct a formal load test if required, confirm phase balance, and document the final configuration for future maintenance.
