Vertiv Liebert GXT5 External Battery Cabinet - 5/6kVA/144V | MV

The Vertiv Liebert GXT5 External Battery Cabinet is designed to enhance uptime for critical equipment by providing scalable, reliable runtime expansion for Liebert GXT5 UPS systems. Built as an external, hot-swappable, lead-acid battery solution, this 2U cabinet integrates seamlessly with compatible GXT5 models to deliver extended protection against power interruptions. Its automatic detection feature makes installation quick and accurate, ensuring your UPS is correctly configured the moment the cabinet is connected. This means less downtime during deployment and upgrades, and more predictable performance during outages.

• Seamless runtime expansion for 5/6 kVA systems: Add external battery capacity to GXT5-5000MVRT4UXLN or GXT5-6000MVRT4UXLN to significantly extend outage protection. By matching the cabinet’s 144V lead-acid bank with your UPS, you can tailor backup durations to your specific critical load, data protection requirements, and organizational service levels. This scalable approach supports longer maintenance windows, safer shutdowns for sensitive equipment, and improved resilience for small to mid-size data centers, server rooms, or edge deployments.
• Hot-swappable lead-acid batteries for maintenance without downtime: The external cabinet is designed for hot-swapping, allowing battery replacement or upgrades without powering down connected equipment or interrupting ongoing operations. This feature is ideal for environments that require continuous availability, enabling personnel to perform battery service while the UPS and protected loads stay online.
• Auto-detection for quick, accurate installation: When connected to a compatible GXT5 UPS, the cabinet communicates its presence and parameters to the controller. The auto-detect capability configures voltage, battery status, and parity automatically, reducing the risk of misconfigurations and speeding up the commissioning process. This reliable self-diagnostic behavior helps ensure that the UPS and external cabinet work together smoothly from day one.
• Rugged, space-efficient 2U rack-mount enclosure: Engineered as an external cabinet with a compact 2U form factor, it aligns with standard 19-inch rack installations. The sturdy enclosure, designed for data centers and IT closets, protects the battery bank from environmental hazards while maintaining easy access for service and maintenance. Its clear cable pathways and mounting compatibility simplify integration into existing rack layouts without sacrificing protection or performance.
• Easy integration with Vertiv monitoring and management tools: The GXT5 External Battery Cabinet works with Vertiv’s monitoring ecosystem to track battery health, runtime extension, and alert notifications. This visibility allows IT teams and facilities staff to anticipate battery maintenance, plan replacements, and coordinate with service windows. Centralized monitoring supports proactive uptime strategies and aligns with DCIM goals for capacity planning and risk mitigation.

How to install Vertiv Liebert GXT5 External Battery Cabinet

• Verify compatibility and readiness: Confirm that your existing UPS is a compatible GXT5 model (GXT5-5000MVRT4UXLN or GXT5-6000MVRT4UXLN) and that you have clearance for a 2U, 144V external cabinet in your rack space. Ensure the environment provides adequate ventilation and temperature control to maximize battery lifespan and performance.
• Prepare the rack and cabinet: Clear a 19-inch rack location with proper airflow around the cabinet. Remove packaging, inspect for any transit damage, and gather the required mounting hardware and connection cables as specified by Vertiv’s installation guidelines.
• Mount the cabinet in the rack: Slide the external battery cabinet into the designated 2U rack space, align the rails, and secure the unit with the appropriate screws. Ensure the cabinet sits level and that the door or access panel can be opened for maintenance without obstruction.
• Make electrical and signaling connections: Connect the cabinet to the compatible GXT5 UPS using the recommended communication and DC connections. Follow the auto-detection prompts and verify that signaling lines, if applicable, are intact. Use proper cable management to keep cables organized and minimize strain on connectors.
• Power-on, verify, and test: Power up the UPS and allow the cabinet to communicate. The auto-detection feature should configure the cabinet automatically, after which you can verify battery status, run-time extension, and any alerts. Perform a brief system test to confirm that the UPS and external cabinet are reporting correctly and that the protected load remains stable under test conditions.
