Vertiv Liebert GXT5 UPS - 1500VA/1350W 120V Online Rack/Tower ENERGY STAR

The Vertiv Liebert GXT5 UPS is engineered to safeguard your most vital IT assets with uncompromising reliability and total power confidence. Delivering 1500VA of load-handling capacity and 1350W of real-world power at a 120V nominal, this online (double-conversion) UPS provides pristine, clean power for servers, storage, networking gear, and telecom equipment. Its energy-efficient design and flexible installation options make it an ideal choice for data centers, server rooms, edge deployments, and small to mid-sized IT environments where uptime is non-negotiable. With a compact rack/tower form factor and robust battery technology, the Liebert GXT5 keeps critical workloads running smoothly through outages, brownouts, and transient disturbances while minimizing heat and energy costs.

• The Liebert GXT5 uses online double-conversion topology to deliver a continuous, high-quality pure sine wave output. This means even during input voltage fluctuations or brief outages, connected equipment receives stable voltage and frequency, dramatically reducing the risk of data loss, corrupted transactions, or hardware stress. This reliability is essential for rack-mounted servers, virtualization hosts, SANs, and high-availability applications that demand uninterrupted operation.
• Flexible installation options support both rack and tower deployments, enabling seamless integration into existing IT furniture and cabinet setups. With a compact footprint and adaptable mounting hardware, the GXT5 can fit in tight data center spaces, on adjacent utility racks, or beside critical IT gear in a dedicated equipment room. This versatility helps you optimize space without sacrificing performance or accessibility for maintenance and monitoring.
• Energy efficiency and sustainability are built into the Liebert GXT5. The UPS is Energy Star certified, helping organizations reduce total cost of ownership through lower electricity usage during normal operation. In addition to high efficiency at typical loads, intelligent power management features enable you to optimize runtime versus capacity, preserve battery life, and minimize heat output in densely populated IT environments.
• Intelligent management and intuitive monitoring simplify day-to-day operations. The GXT5 provides multiple connection options, including USB and RS-232 for local management and optional Network Management Card support for remote administration through a standard Ethernet connection. A user-friendly interface and compatibility with Liebert monitoring software enable proactive alerts, graceful shutdowns, and streamlined asset management across multi-rack deployments.
• Maintenance-friendly design features hot-swappable batteries and modular components, reducing downtime during battery exchanges and prolonging the lifespan of the UPS. Field-replaceable batteries and straightforward, tool-assisted maintenance minimize service interruptions and help you extend runtime in mission-critical setups. This means you can quickly recover from outages and maintain service levels without significant hands-on downtime.

how to install Vertiv Liebert GXT5 UPS

Installing the Liebert GXT5 is designed to be straightforward for IT professionals and facilities staff. Begin by choosing a location that accommodates both the rack/tower form factor and adequate ventilation. Ensure clearance around the unit for proper cooling and access to the power input and outlet connections. If mounting in a rack, use the included rails and hardware to secure the unit firmly to prevent movement during maintenance or under vibration. For tower use, install the unit on a stable, level surface with unobstructed airflow.

Next, connect your critical devices to the UPS output outlets and route the power input cable to a properly grounded 120V electrical circuit. If you plan to monitor the UPS remotely, connect the USB or RS-232 cable to a management workstation and install the appropriate Liebert monitoring software as directed in the user guide. If you require central monitoring across multiple units, consider adding the optional Network Management Card and configuring SNMP, email alerts, or integration with your existing data center infrastructure management tools.

Power on the unit and allow the batteries to charge to full capacity before placing a normal load on the system. Run a diagnostic battery test to verify capability and ensure that all indicators show normal status. If you have external battery modules, connect them according to the manufacturer’s instructions to extend runtime for longer outages or planned maintenance windows. Finally, customize alert thresholds, event notifications, and shutdown policies to align with your organization’s RPO (recovery point objective) and RTO (recovery time objective) requirements.

Ongoing upkeep includes periodic self-tests, battery health checks, and firmware or software updates as recommended by Vertiv. Maintain a clean environment, free of excessive dust and moisture, and ensure the UPS is inspected regularly as part of your IT equipment lifecycle management. By following these steps, you’ll maximize protection for servers, storage arrays, and network gear while simplifying the operational management of your power infrastructure.
