Vertiv RS500 Flush-Mount Rack Shelf for 19IN Racks
Overview
The Vertiv RS500 is a flush-mount shelf designed to integrate Liebert® GXT5 uninterruptible power supplies into standard 19-inch-wide racks. This accessory eliminates the need for separate mounting hardware or external UPS stands, keeping your rack footprint compact while supporting the entire Liebert GXT5 family — from 500VA through 10kVA units. If you're consolidating power backup into a single rack with network infrastructure, routers, or security equipment, the RS500 delivers space efficiency without sacrificing stability or accessibility.
Key Features
- Universal GXT5 compatibility: The RS500 accommodates the complete Liebert GXT5 UPS range (500VA to 10kVA), meaning you can standardize on a single shelf model across multiple deployments — no model-specific variants to track or inventory separately.
- Flush-mount design: Installs directly into standard 19-inch rack rails without protruding beyond the front or rear rails, preserving access aisles and allowing dense placement of adjacent equipment.
- Tool-free installation: Mounting requires no tools or custom modifications to the rack frame — rapid deployment on site, particularly valuable in time-constrained builds.
- Supports up to 3kVA for telecom/branch office setups: Specific kit variants (2UTELECOMRKIT, WMBKT2U, WMBKT2USS) handle Liebert GXT5 units up to 3kVA, making the RS500 suitable for distributed branch offices, retail locations, or remote surveillance hubs that cannot accommodate larger UPS footprints.
- Rigid structural support: Engineered to handle the full weight and operational vibration of a running UPS without flex or settling, critical in rack environments subject to vibration from cooling fans or adjacent equipment.
- Improves thermal management: Mounting the UPS at eye level on the shelf ensures unrestricted airflow above and below the unit, preventing heat stratification that would reduce battery cycle life or trigger early thermal shutdowns during extended power events.
Integration & Compatibility
The RS500 pairs directly with Liebert GXT5 UPS units across the entire 500VA–10kVA spectrum. For smaller deployments, related Vertiv mounting kits address specific form factors: the 2POSTRMKIT and 2UTELECOMRKIT are optimized for 3kVA and below, while the RMKIT18-32 scales across the full family. All kits share the same 19-inch mounting standard, ensuring interchangeability across your infrastructure. When planning your rack layout, account for the UPS depth (typically 13–16 inches for GXT5 models) and ensure clearance above and below for cable routing and ventilation.

Frequently Asked Questions
Q: Does the RS500 work with all Liebert GXT5 UPS models?
A: Yes. The RS500 is rated for the entire Liebert GXT5 family, 500VA through 10kVA. Some kit variants (2UTELECOMRKIT, WMBKT2U, WMBKT2USS) are limited to 3kVA, so verify the specific part number against your UPS capacity.
Q: Can I install the RS500 without tools?
A: The RS500 is designed for tool-free installation into standard 19-inch rack rails, streamlining site deployment.
Q: What is the footprint impact of mounting a UPS on the RS500?
A: The RS500 flush-mount design does not extend beyond the front or rear of the rack, preserving aisle space and allowing dense equipment placement without violating hot-aisle/cold-aisle containment.
Q: Is the RS500 suitable for small branch office or retail deployments?
A: Yes. Specific kit variants support GXT5 units up to 3kVA, ideal for branch offices, retail sites, or remote surveillance locations with limited rack space.
Q: What mounting standard does the RS500 use?
A: The RS500 installs into standard 19-inch-wide racks using universal mounting rails, ensuring compatibility across most commercial and enterprise infrastructure.
The RS500 is a straightforward but critical accessory if you're integrating a Liebert GXT5 UPS (500VA to 10kVA) into a standard 19-inch rack without consuming floor or wall space. What makes it valuable is the flush-mount design — the UPS sits directly on the shelf without protruding past the rack rails, which matters a lot in tight data closets or surveillance control rooms where aisle width is already compressed. I've seen too many deployments where someone just stacks a UPS on a generic shelf, blocks cable routing, or creates fire-code violations. The RS500 solves that problem by design.
Technical Highlights:
- Universal GXT5 support (500VA–10kVA): One shelf model covers your entire UPS portfolio — no need to track separate kits for different capacities, reducing spare-parts overhead and standardizing procurement.
- Flush-mount footprint: Equipment installed flush with the rack rails preserves aisle compliance and allows you to run cables on both sides of the equipment without creating fire-code pinch points.
- Tool-free installation into 19-inch racks: If you're standing in a telecom closet or surveillance vault on deployment day, you don't want to hunt for hardware or modify the rack frame — the RS500 slides into standard rails and locks without fasteners.
Deployment Considerations:
- Verify the specific kit variant against your UPS capacity — the RS500 supports the full GXT5 range, but some variants (2UTELECOMRKIT, WMBKT2U, WMBKT2USS) max out at 3kVA. Don't assume; check the part number before ordering.
- Plan for cable clearance above and below the shelf — UPS units generate heat, and blocking ventilation will reduce battery cycle life or trigger thermal shutdowns during extended outages.
The RS500 is the right choice for branch office and retail surveillance hubs where a GXT5 UPS needs to fit into a standard rack alongside network gear, but you can't afford to sprawl equipment into aisles or sacrifice compliance. It's not sexy, but it solves a real constraint in tight infrastructure spaces.
