Vertiv RS800 Center-Mount Shelf for 23-Inch Wide Racks
Overview
The Vertiv RS800 is a center-mount rack shelf engineered for 23-inch wide rack enclosures, designed to support the complete Vertiv Liebert GXT5 UPS product family from 500VA through 10kVA. If you are deploying any GXT5 unit and working within a 23-inch rack infrastructure, the RS800 is the purpose-built mounting solution that keeps your UPS properly seated and structurally supported without improvisation or adapter hardware.
The RS800 covers the widest compatibility range in the GXT5 accessory lineup — the entire Liebert GXT5 family from 500VA to 10kVA — meaning you can standardize on this shelf across mixed-capacity deployments rather than stocking multiple SKU variants. That matters in data closets and server rooms where rack configurations evolve as power density requirements change. Compare this to sibling kits like the 2POSTRMKIT or WMBKT2U, which are limited to GXT5 models up to 3kVA only — the RS800's full-family coverage is its primary advantage over those options.
If you are integrating UPS and power protection hardware into a 23-inch rack infrastructure alongside network or surveillance equipment, the RS800 eliminates the guesswork of third-party shelf compatibility. Vertiv designed this shelf specifically for the GXT5 form factor, so fitment and weight distribution are validated at the factory level rather than left to field measurement.
Key Features
- Full GXT5 Family Coverage (500VA–10kVA): Unlike accessory kits restricted to sub-3kVA GXT5 units, the RS800 accommodates the entire Liebert GXT5 range — useful when your rack houses higher-capacity units or when you expect to scale UPS capacity over time without replacing mounting hardware.
- 23-Inch Wide Rack Compatibility: Targets the 23-inch rack form factor specifically, making this the correct choice for legacy telecom-style or older enterprise rack enclosures where standard 19-inch accessories do not fit.
- Purpose-Built for Liebert GXT5: Vertiv-validated fitment means no shimming, no custom adapters, and no voided support agreements from using generic shelf hardware with a precision UPS chassis.
Compatibility
The RS800 supports the entire Liebert GXT5 UPS family (500VA to 10kVA) in 23-inch wide rack enclosures and accessories. For 19-inch rack environments, evaluate the RS500, RS600, or RS700 within the same GXT5 accessory family. For wall-mount or 2-post telecom rack configurations with GXT5 units up to 3kVA, see the WMBKT2U or 2POSTRMKIT alternatives. Consult the power and UPS accessories category for the full range of Vertiv rack integration hardware.
Frequently Asked Questions
Q: Which UPS models does the RS800 support?
A: The RS800 supports the entire Liebert GXT5 UPS family, from 500VA through 10kVA.
Q: What rack width does the RS800 fit?
A: The RS800 is designed for 23-inch wide rack enclosures. It is not intended for standard 19-inch racks.
Q: How does the RS800 differ from the 2POSTRMKIT or WMBKT2U?
A: The 2POSTRMKIT and WMBKT2U are limited to GXT5 units up to 3kVA. The RS800 covers the full GXT5 family including units from 500VA to 10kVA, making it the appropriate choice for higher-capacity installations.
Q: Is the RS800 compatible with non-GXT5 Vertiv UPS models?
A: Based on available evidence, the RS800 is validated specifically for the Liebert GXT5 UPS family. Compatibility with other Vertiv UPS lines is not confirmed in the manufacturer documentation.
The RS800 stands out in the Vertiv GXT5 accessory line specifically because it covers the full 500VA–10kVA GXT5 range — a detail that matters when you are managing a rack room with mixed UPS capacities. I have seen integrators order the cheaper sub-3kVA kits and then hit a wall when a higher-capacity GXT5 unit arrives on site. The RS800 eliminates that problem for 23-inch rack environments.
Technical Highlights:
- Full-family GXT5 coverage: Validated for every GXT5 unit from 500VA to 10kVA — no need to stock separate shelf SKUs for different capacity tiers in the same rack room.
- 23-inch rack specificity: Targets the narrower 23-inch rack form factor that appears in older enterprise data closets and telecom infrastructure — a shelf designed for this width seats correctly without modification.
- Vertiv-native fitment: Purpose-engineered for the GXT5 chassis geometry, which matters for weight distribution and vibration isolation in environments where UPS units run under sustained load.
Deployment Considerations:
- Verify your rack is genuinely 23-inch wide before ordering — 19-inch racks are far more common in modern deployments, and the RS500/RS600/RS700 family covers those environments for GXT5 installations.
- Evidence does not confirm load rating, unit height (U), or material specifications for the RS800 — request the Vertiv installation sheet before committing to a high-density rack layout where shelf load capacity is a factor.
The RS800 is the right call specifically for facilities running 23-inch rack infrastructure with Liebert GXT5 UPS units at or above 3kVA — legacy enterprise data rooms, older telecom equipment rooms, and campus facilities that standardized on 23-inch enclosures before 19-inch became universal.
