Eaton 9PXM 4000VA UPS — Modular, Scalable Online Double-Conversion Power

The Eaton 9PXM UPS is a scalable, modular online double-conversion power solution engineered for critical IT loads, data centers, and demanding network applications. Designed to deliver high reliability with the lowest total cost of ownership, the 9PXM uses plug-and-play 4 kVA power modules to provide expanding N+X redundancy and robust protection for sensitive equipment. With a compact 14U footprint and rack/tower flexibility, this UPS supports future growth while maintaining tight voltage regulation, fast transient response, and resilient performance in mission-critical environments.

• Modular scalability for growing IT environments — The 9PXM uses four plug-and-play 4 kVA power modules, enabling easy expansion from a baseline so you can add capacity and redundancy as your load increases. This modular design supports N+X configurations, helping you achieve higher availability without overhauling the entire system.
• Online double-conversion protection you can trust — True online double-conversion technology delivers clean, precise output voltage and uninterrupted power to critical equipment. The UPS isolates connected gear from input disturbances, ensuring excellent voltage regulation, fast response to disturbances, and consistent performance even during input dips or outages.
• Flexible power delivery for mixed outlets and hardwired input — The unit accommodates two L6-30R outlets and four 5-20R outlets, giving you versatile connection options for servers, storage, networking equipment, and peripherals. The hardwired input provides a secure, dedicated connection to campus or data-center electrical infrastructure for optimized reliability.
• Cybersecure networking and remote management — Includes a Cybersecure Network Card for protected remote monitoring and management. This capability supports secure communication with Eaton software and standard network management tools, enabling proactive monitoring, firmware updates, and remote shutdown or control when needed.
• Designed for data centers with a compact 14U footprint — The Eaton 9PXM fits eight- or twelve-slot tower enclosures and is designed for dense data-center racks. The 14U form factor combines space efficiency with modular expandability, making it suitable for both deployment in new builds and upgrades to existing infrastructure.

how to install Eaton 9PXM UPS

Installing the Eaton 9PXM UPS involves careful planning, proper rack placement, and correct wiring to ensure maximum reliability and service life. Follow these steps to get up and running quickly while preserving uptime and safety:

• Plan your space and load — Determine the available 14U rack space and map your critical devices to the 2 x L6-30R and 4 x 5-20R outlets. Establish a dedicated 208–240 VAC feed from a suitable electrical panel or circuit, ensuring appropriate overcurrent protection and clearance for maintenance access.
• Install the modular power modules — With hot-swappable 4 kVA modules, install the first module into the appropriate slot per Eaton installation guide. Ensure each module is fully seated and follow the sequence for adding additional modules to reach the desired capacity and redundancy (N+X).
• Mount the UPS — Place the 14U chassis into the chosen rack space, or install in a tower configuration if space or facility constraints require. Secure all mounting screws and verify that cooling airflow is unobstructed for optimal thermal performance.
• Connect input and outputs — Connect the hardwired input to the 208–240 VAC supply, ensuring proper grounding and adherence to local electrical codes. Connect IT equipment to the 2 x L6-30R outlets and 4 x 5-20R outlets, distributing loads to balance power draw and minimize outlet crowding.
• Configure network and management — Install the Cybersecure Network Card, connect it to your network, and configure IP settings, alert thresholds, and monitoring preferences. Install Eaton’s management software (such as Intelligent Power Manager or similar) on a connected server or management console for real-time monitoring and alerting.
• Power up and perform a test — After wiring is complete, perform a controlled startup, verify 9PXM self-test runs, and confirm proper output voltage and recovery behavior under simulated fault conditions. Validate that redundant modules engage correctly and that load-sharing is functioning as intended.
• Schedule regular maintenance — Establish a maintenance plan for firmware updates, module inspections, battery health checks (if applicable), and periodic battery replacement planning to preserve performance and availability over time.
