Vertiv Liebert GXT5 3000VA Rack/Tower UPS

Power reliability is a foundational requirement for modern IT environments. The Vertiv Liebert GXT5 3000VA Rack/Tower UPS is designed to protect critical workloads by delivering clean, continuous power to servers, storage arrays, networking gear, and virtualization platforms. Built for 208V infrastructure, this 2U UPS can be mounted in a standard rack or configured as a freestanding tower, offering flexible deployment for data centers, edge facilities, and compact server rooms. With scalable runtime options and integrated remote monitoring through the RDU card, the GXT5 helps minimize downtime, safeguard data integrity, and ensure graceful shutdowns during outages, brownouts, or transient power disturbances. Its efficient design, quiet operation, and straightforward management make it an essential component for protecting business-critical applications from power-related threats.

• Smart, scalable power protection for critical IT equipment: The GXT5 delivers 3000 VA (approximately 2700 W) of reliable capacity, ensuring uninterrupted operation for servers, virtualization hosts, storage solutions, switches, and backup applications during outages and voltage fluctuations.
• Flexible mounting for rack or tower deployments: The 2U form factor enables seamless rack installation in data centers, while the tower configuration accommodates offices, telecom rooms, or edge environments where floor space is at a premium.
• 208V readiness with robust voltage regulation: Optimized for 208V infrastructure, the GXT5 provides stable output and automatic voltage regulation to handle input variations, reducing unnecessary battery discharge and extending runtime where possible.
• Extended runtime options with external batteries and RDU card: When longer uptime is needed, attach external battery modules to scale the runtime, and leverage the RDU card for local and remote monitoring, alerts, and graceful shutdowns.
• Intelligent management and seamless integration: The GXT5 supports multiple management interfaces, including the RDU card, USB, and serial connectivity, enabling integration with Vertiv software and IT service management workflows for proactive maintenance and rapid response to events.

How to install Vertiv Liebert GXT5 3000VA Rack/Tower UPS

• Prepare the installation site: Choose a dry, well-ventilated area with unobstructed airflow. Ensure there is adequate clearance around the unit for service access and cooling. Confirm the 208V power source matches the UPS input requirements and that the circuit can handle the startup and running load of the connected equipment.
• Decide on the mounting method: If using a rack installation, install the included rack rails per the manufacturer’s instructions and mount the UPS securely in a 2U space. For floor-based deployment, ensure a stable surface with level feet and sufficient alignment space for accessories and external battery modules.
• Mounting and positioning: For rack mounting, align the ears and screws with the rack rails and tighten evenly to avoid warping. If using the tower configuration, place the unit on a solid surface with at least several inches of clearance on all sides for cooling and access to the rear ports.
• Connect loads and input power: Plug critical devices (servers, storage, switches) into the UPS outlets, ensuring outlet ratings match the connected equipment. Connect the UPS input power cable to a dedicated 208V circuit, using appropriately rated wiring and a suitable circuit protector as required by local codes.
• Enable and configure management features: Insert the RDU card (if not pre-installed) and connect the USB/serial cables to a management workstation. Power on the UPS and perform the initial self-test. Use the RDU interface to configure basic settings (voltage sensitivity, ECO mode if available, notification preferences) and register the unit with Vertiv monitoring software for ongoing visibility into health, runtime, and events.
• Attach external battery modules (if extended runtime is needed): If you plan to extend runtime, connect compatible external battery packs following the manufacturer’s wiring diagrams. Verify all battery connections are secure and that the runtime goals align with your load profile.
• Test operation and establish a shutdown plan: Simulate a power interruption to verify automatic transfer to battery power and the execution of a graceful shutdown for critical devices. Confirm notification alerts, log entries, and event reporting are functioning as expected through the RDU and monitoring software.

Frequently asked questions

• What equipment can the Vertiv Liebert GXT5 protect? The GXT5 is designed to protect servers, storage devices, networking gear, virtualization hosts, and other critical IT equipment that operate on 208V infrastructure, helping to prevent data loss during power events and ensuring orderly shutdowns when needed.
• Can it be installed as both a rack-mount and a tower? Yes. The GXT5 3000VA is a 2U rack/tower convertible unit, allowing flexible deployment in data centers, edge locations, and office environments depending on space, orientation, and operational needs.
• Does it support extended runtime? Yes. The system can be paired with external battery modules to extend runtime, which is especially useful for protecting workloads that require longer duvet of uptime between outages or when recharging time must be minimized.
• What management options are available? The UPS includes an RDU (Remote Display Unit) card for local and remote monitoring. It also supports USB and serial connections and can integrate with Vertiv monitoring software to deliver alerts, health metrics, event history, and energy management insights.
• Is it suitable for edge computing and small data centers? Absolutely. The Liebert GXT5’s compact 2U form factor, 208V compatibility, and scalable runtime make it a strong fit for edge deployments, small data centers, and server rooms where reliable power is critical and space is limited.
• What maintenance or replacement considerations exist? VRLA batteries require periodic health checks and eventual replacement after years of service. If external battery modules are used, ensure they are sourced from Vertiv-approved options and are properly matched to the UPS for optimal runtime and performance.
