Protect your most valuable IT assets with the Vertiv Liebert GXT5 UPS. Engineered for rack-mount deployments in data centers, server rooms, and edge environments, this online double-conversion UPS delivers pristine power to servers, storage, networking, and telecom equipment. With a 15kVA / 15kW rating, configurable output for 208V and 120V, and scalable runtime options, the GXT5 is designed to keep critical workloads operational through outages, brownouts, and transient electrical disturbances. Its modular design emphasizes reliability, serviceability, and energy efficiency—so you can safeguard uptime while controlling total cost of ownership.

• Premium online double-conversion protection provides continuous, isolated power conversion from input to output. The Liebert GXT5 maintains tight voltage regulation, superb transient response, and 100% continuity of power to critical devices. With zero transfer-time during disturbances, data integrity remains intact and unexpected downtime is minimized, even during complete input faults or sudden surges. This is the backbone of robust IT resilience for mission-critical applications and high-availability environments.
• Scalable runtime with modular battery solutions delivers configurable uptime as your workloads grow. The GXT5 supports hot-swappable battery modules and optional external battery cabinets, enabling extended runtimes without interrupting service. Whether you’re protecting a small cluster of servers or a larger rack of virtualized workloads, you can tailor the energy storage to meet evolving service-level objectives while simplifying maintenance with modular, easy-to-replace components.
• Rack-ready, flexible voltage configurations is built for compact data-centre footprints and stacked IT closets. The UPS supports 208V and 120V output configurations in a standard 19-inch rack enclosure, combining power quality with space efficiency. Auto-sensing input and output frequencies adapt to regional grids, ensuring seamless operation across global deployments. Its rugged chassis and hot-swappable power modules are designed for continuous operation in busy IT environments where space is limited but reliability cannot be compromised.
• Intelligent monitoring and remote management empower proactive protection and rapid response. An intuitive LCD interface provides real-time health and performance data, while multiple communication ports (USB, RS-232, Ethernet) enable remote supervision, alerting, and integration with enterprise monitoring ecosystems. Compatibility with Vertiv monitoring software and SNMP protocols means you can visualize load, battery health, and event history from a centralized dashboard, streamline maintenance windows, and optimize shutdown policies across multiple racks.
• Efficient, quiet, and maintenance-friendly design emphasizes energy efficiency and ease of service. The GXT5 uses advanced cooling and power-electronics to minimize heat generation and noise, helping to reduce operating costs in data centers and office IT rooms. The modular architecture simplifies service work—batteries and hot-swappable components can be replaced quickly without removing the UPS from the rack, reducing downtime and extending asset life in demanding 24/7 environments.

How to install Vertiv Liebert GXT5 UPS

• Plan your rack layout and verify that the 19-inch enclosure has adequate clearance for airflow, service access, and cable management. Confirm floor weight capacity and grounding requirements before installation.
• Mount the UPS securely in the rack using the supplied rails and hardware. Align the chassis with front-door clearance and ensure that the unit is level to support proper door operation and cooling airflow.
• Connect the input power to a dedicated circuit that meets the UPS specifications. Use appropriately rated breakers and proper cabling to minimize impedance and ensure clean power input.
• Connect your critical loads to the UPS output or distribution shelf. Distribute load evenly across outlets to avoid overloading any single branch, preserving protection for all connected devices.
• Install and configure battery modules or external battery cabinets as needed. Power on and allow the batteries to initialize; verify that the UPS completes its internal self-test with no faults.
• Establish communications with management interfaces (USB, RS-232, Ethernet). Install recommended Vertiv software or agents to enable remote monitoring, alerting, and integration with your existing ITSM or data-center infrastructure.
• Configure operating parameters such as voltage selection (208V or 120V), frequency, alarm thresholds, auto-start behavior, and shutdown policies. Save and apply these settings to ensure consistent protection aligned with your IT policy.
• Perform a controlled test to simulate a real event: disconnect the input power and observe proper transfer, load support, audible alerts, and monitoring system notifications. Validate that the shutdown sequence is correctly triggered for safe power-down of connected equipment if needed.
