Eaton 9PXM 12-Slot External Battery Cabinet for 9PXM UPS – 21U Rack/Tower, 3 EBMs, TAA

The Eaton 9PXM 12-Slot External Battery Cabinet is a purpose-built extension that dramatically extends the runtime of your 9PXM online double-conversion UPS. Designed for reliability under load, this external enclosure provides scalable, long-term power backup for mission-critical applications across colocation facilities, edge data centers, industrial environments, and commercial operations. With 12 battery slots and the ability to add up to three External Battery Modules (EBMs), you can tailor runtime to match your organization’s service level agreements and tolerance for downtime. Its flexible 21U rack or tower configuration ensures straightforward integration into existing data-center footprints, while its rugged construction and TAA-compliant design meet the stringent requirements of enterprise and government deployments. The cabinet is engineered to work seamlessly with Eaton’s 9PXM UPS ecosystem, enabling streamlined management, proactive monitoring, and simplified lifecycle planning—so your IT infrastructure remains resilient even in the face of unpredictable power events.

• The 12-slot external battery cabinet dramatically expands runtime for the Eaton 9PXM UPS, delivering extended protection for critical workloads during outages. This enclosure is purpose-built to support demanding power profiles and high-availability environments, ensuring business continuity when the grid falters. By providing additional energy storage capacity, it helps you meet recovery time objectives (RTOs) and uptime commitments in data-heavy operations such as virtualization, databases, and real-time analytics.
• Scalability is at the heart of this design: add up to three EBMs to reach the exact level of resilience your organization requires. Each EBM increases available energy and discharge duration, allowing you to adjust runtime in response to seasonal workloads, growth plans, or seasonal demand spikes. The modular approach minimizes risk and capital expenditure by enabling staged investments aligned with capacity growth.
• Flexible deployment options make it suitable for a variety of environments. The enclosure supports both 21U rack mounting and tower configurations, enabling installation in traditional data centers, colocation spaces, edge sites, retail floors, or manufacturing floors where footprint and accessibility matter. Its modular form factor helps optimize airflow, cable management, and serviceability while keeping critical hardware protected and accessible for maintenance.
• Seamless integration with Eaton’s monitoring and management tools ensures you can track health, remaining runtime, and battery performance from a centralized console. The cabinet works in concert with the 9PXM UPS line, providing coherent status reporting, alerts, and lifecycle planning. This holistic approach reduces administrative overhead, improves response times to potential issues, and helps optimize preventive maintenance schedules to maximize uptime.
• Built for demanding environments and governed by rigorous procurement standards, the cabinet is TAA-compliant and constructed to withstand industrial and commercial conditions. Its robust enclosure provides protection for batteries in a wide range of temperatures and humidity levels, delivering consistent performance in data centers, retail backrooms, government facilities, and factory floors. The design emphasizes safety, reliability, and long service life in active, mission-critical deployments.
