Vertiv Center-Mount Shelf for Liebert GXT3/GXT4 UPS in 23-Inch RS800 Rack

The Vertiv Center-Mount Shelf is a purpose-built mounting solution designed to securely house Vertiv Liebert GXT3 or GXT4 uninterruptible power supplies inside 23-inch wide telecom and relay racks. Engineered for single mounting rail installations, this shelf delivers a balanced, space-saving foundation that simplifies power management, enhances rack organization, and promotes reliable uptime in data centers, server rooms, and network closets. With its sturdy construction, thoughtful design for airflow and cable management, and straightforward installation, this center-mount shelf makes the most of your existing RS800 or other 23-inch racks while safeguarding your critical power equipment.

• Secure compatibility with Liebert GXT3 and GXT4 UPS units in standard 23-inch telecom/relay racks. The center-mount design positions the UPS for optimal front accessibility and balanced load distribution, helping minimize rack deflection and vibration. Specifically engineered for single mounting rail type racks, this shelf enables a clean, professional install without the need for custom rails or adapters. By centering the UPS in a fixed, stable plane, technicians can perform battery checks, firmware updates, and routine maintenance with ease while keeping cabling neatly contained and out of the way.
• Rugged, data-center ready construction. Built from heavy-duty steel with a durable powder-coated finish, the shelf stands up to the daily wear and tear of busy rack environments. The robust frame supports the weight of Liebert GXT3 or GXT4 units plus any included accessories, providing long-term reliability under normal operating conditions. Precision-drilled mounting holes allow for fast, secure attachment to standard rails, reducing installation time and ensuring a perfectly level, steady platform for the UPS. The solid build also contributes to reduced noise and vibration, which helps protect sensitive electronics mounted nearby.
• Ventilated design and intelligent cable management. The shelf surface and surrounding structure promote airflow around the UPS, helping to maintain optimal temperatures and protect battery health. Perforations and open geometry support efficient cooling, while thoughtfully placed cutouts and channels guide power and data cables away from hot zones and connectors. This thoughtful layout enables tidy, organized cable runs and simplifies future UPS swaps or servicing without compromising airflow or access to essential connectors.
• Easy, tool-efficient installation. The Vertiv center-mount shelf is designed to align with standard 23-inch rack rails, featuring pre-drilled holes and inclusive mounting hardware for a quick, straightforward setup. No specialized tools or intrusive modifications are required—the UPS is simply placed on the shelf, aligned, and secured with the supplied fasteners. Once installed, the center-mount orientation keeps the weight centered, reducing stress on rails and ensuring durable performance through repetitive maintenance cycles.
• Space optimization, serviceability, and future-proofing. By mounting the Liebert GXT3 or GXT4 UPS in the center of the rack, the shelf frees vertical rail space for other devices and allows easy front and rear access for cable management, battery checks, and routine servicing. The compact footprint of the center-mount shelf integrates seamlessly with existing rack infrastructure, maximizing usable space without sacrificing accessibility, redundancy, or airflow—key considerations for high-density data centers and edge environments alike.
