VERTIV VRA Rail Conversion Kit – 45U, 21" Rails to 45U for 800 mm Wide Racks

The Vertiv VRA6045 Rail Conversion Kit is a purpose-built solution designed to unlock greater rack versatility in data centers that demand high-density deployments. By enabling a seamless exchange from 21" EIA rails to a centered 45U mounting plane within 800 mm wide racks, this kit provides a robust foundation for scaling equipment footprints without needing to replace entire racks. It integrates cleanly with standard 19-inch equipment and accessories, preserving familiar installation practices while delivering enhanced stability for heavy, tall, or multi-component servers, storage nodes, and networking appliances. The VRA6045 aligns with industry mounting standards, helping operators maintain consistent workflows, reduce downtime, and optimize space utilization. Beyond performance, Vertiv emphasizes sustainability: reusing existing rails and components minimizes waste and lowers environmental impact, contributing to greener data-center operations without compromising reliability. The result is a reliable, future-ready mounting solution that supports longer equipment lifecycles, reduces wear on mounts and rails, and simplifies upgrade paths as your IT portfolio evolves.

• Rail conversion for 800 mm wide racks: The VRA6045 enables the exchange of traditional 21" EIA rails for a centered 45U mounting configuration, expanding room for taller, more capable hardware while keeping the rack footprint constant and avoiding costly rack replacements.
• 45U mounting height for high-density deployments: Specifically designed to support 45U configurations, this kit accommodates large controllers, blades, and storage devices, delivering stable support and precise alignment to prevent sag, misalignment, or gear shifting during operation.
• Rugged steel construction with durable finish: Built to endure the rigors of busy data centers, the VRA6045 uses heavy-duty steel and a protective finish that resists wear and corrosion, ensuring long-term reliability under frequent equipment swaps and routine maintenance.
• Sustainability and lifecycle benefits: By leveraging existing rails and minimizing new component production, this kit helps reduce material waste and lowers carbon footprint, supporting environmentally responsible rack modernization and scalable uptime.
• Easy, tool-friendly installation with clear alignment: Thoughtful design and straightforward hardware integration enable technicians to reconfigure racks quickly, with confidence in alignment and stability, reducing downtime and potential misalignment during upgrades.

How to install VRA6045

• Step 1: Prepare your rack — verify that you have an 800 mm wide enclosure and accessible 21" EIA rails suitable for conversion; ensure the rack is de-energized and safely supported before starting.
• Step 2: Gather required tools and components — confirm you have the VRA6045 kit and any compatible fasteners or mounting hardware recommended by Vertiv; organize hardware for quick access during installation.
• Step 3: Remove or reposition existing rails as needed — if current rails obstruct the conversion, carefully detach them following established safety procedures and set them aside for reassembly or reuse where applicable.
• Step 4: Align the VRA6045 with the rack rails — position the kit to center the 45U mounting plane within the enclosure, ensuring that all mounting points line up with the rack posts and that edges are level to prevent tilt or bind during operation.
• Step 5: Secure the conversion kit — fasten the VRA6045 to the rack using the included hardware or manufacturer-approved fasteners, tightening evenly to avoid distortion or misalignment of rails.
• Step 6: Install the new center-mounted 45U rail plane and verify — attach the newly configured rails in the center of the rack, confirm secure engagement at every mounting point, and check for smooth travel of any slide rails or shelf components.
• Step 7: Reinstall IT equipment and manage cabling — return servers, storage, and network devices to the rack, route cables with proper separation for airflow, and perform a final alignment review to ensure clearance around doors, cable managers, and cooling paths.
