Liebert MPH2 Outlet Metered & Outlet Switched PDU

The Liebert MPH2 Outlet Metered & Outlet Switched PDU is a purpose-built power distribution solution designed to protect and optimize critical IT loads in demanding data center environments. With hardwired input and output connections, this PDU integrates seamlessly into Vertiv Liebert GXT4 5-6kVA RT208 UPS configurations, delivering reliable, monitored power where you need it most. Its built-in maintenance bypass breaker provides a safe path for UPS servicing without interrupting power to protected equipment, while 4-wire (2P+N+G) wiring ensures robust electrical safety and compliance with modern code standards. Whether you’re deploying a compact edge rack or a full data center rack, the MPH2 delivers precise energy metering, controlled outlet management, and a resilient, scalable power distribution platform that helps you optimize uptime, energy use, and overall infrastructure efficiency.

• Outlet metered and switched PDU: The MPH2 combines real-time energy metering with remote outlet control, delivering granular visibility into power usage and enabling selective outlet management. IT administrators can monitor voltage, current, and power metrics at the outlet level, track load trends, and identify inefficiencies. The built-in switching capability allows controlled power cycling of individual outlets or groups, enabling rapid remediation of unresponsive devices and enhanced resilience for critical servers, storage, and network gear without requiring现场 downtime.
• Hardwired input and output connections: Designed for clean, secure installation in rack environments, the MPH2 provides solid, solder-free connections for both input power and downstream outlets. The hardwired approach reduces cable clutter, minimizes the risk of loose connections, and simplifies routing in dense data centers where space and organization drive reliability. This configuration also supports clean power distribution with reduced impedance, supporting stable performance under peak load.
• Maintenance bypass breaker included: A pivotal feature for any mission-critical deployment, the MPH2 includes a built-in maintenance bypass breaker. This enables safe UPS maintenance, replacement, or testing without interrupting power to essential equipment. By isolating the UPS from the load in a controlled manner, facilities teams can perform service windows with confidence, maintaining uptime for critical workloads while keeping personnel safe during maintenance procedures.
• 4-wire (2P+N+G) configuration: The MPH2 employs a four-wire power system—the two hot phases (2P), a neutral (N), and a protective grounding conductor (G). This arrangement supports balanced power delivery, improves fault protection, and aligns with contemporary electrical codes for equipment in data centers and enterprise IT environments. The 4-wire setup is ideal for supporting modern servers, network devices, and storage arrays that demand reliable neutral references and robust grounding for safe operation.
• Designed for Vertiv Liebert GXT4 5-6kVA RT208 UPS: This PDU is purpose-built to complement the Liebert GXT4 5-6kVA RT208 UPS system. The precise compatibility minimizes integration time, ensures coordinated protection and monitoring, and enhances overall system reliability. With this pairing, users gain seamless power protection, improved visibility into energy use, and a straightforward path to scalable IT power management that can grow with your infrastructure needs.

How to install Liebert MPH2 Outlet Metered & Outlet Switched PDU

• Plan placement and safety: Install the MPH2 close to your Vertiv Liebert GXT4 UPS in a properly rated rack, ensuring clear access for maintenance and monitoring. Engage a licensed electrician and follow all local electrical codes and rack-mouting guidelines to guarantee a compliant, safe installation.
• Power down and prepare: Before wiring, power down the UPS system and verify that the installation area is free of live voltage. Confirm that the rack and mounting hardware meet the PDU’s mounting dimensions and weight requirements, and gather the wiring diagram and any installation manuals for reference during the wiring process.
• Connect the 4-wire input: Connect the incoming supply to the MPH2’s input terminals following the provided wiring diagram. Attach the two hot legs (L1 and L2) to their designated terminals, then connect the neutral (N) and protective earth (G) to their respective bars. Double-check tightening torque and polarity to ensure a solid, safe connection and proper grounding.
• Wire outputs and route loads: Connect downstream outlets or bus interfaces according to your equipment layout. Use appropriate cable management techniques—cable ties, organizers, and routing plans—to minimize clutter and maximize airflow. Label outlet groups if you intend to implement switching policies for different device classes or service levels.
• Power, test, and verify: Restore power carefully and monitor the MPH2’s metering readouts and outlet states. Validate that energy data is reported accurately, controlled outlets respond to on/off commands, and the maintenance bypass is functioning as intended for safe UPS servicing. Confirm that the UPS and connected equipment maintain uptime during normal operation and in simulated fault scenarios as required by your IT policies.
