Vertiv VRX-45U2436-W-SQM6 45U Adjustable-Depth Open Frame Rack
Overview
The Vertiv VRX-45U2436-W-SQM6 is a 45U open-frame rack finished in Winter White, designed for data center, server room, and network equipment deployments where structured, accessible mounting is the priority. The VRX series ships in multiple height configurations — 45U, 52U, and 59U — making it adaptable to room-height constraints without changing the footprint. The 24–36-inch adjustable depth means you can fit shallow network gear or deep 1U/2U servers in the same frame, dialing in the depth at install rather than before it. For integrators speccing a rack enclosure for a mixed equipment bay, that flexibility reduces SKU proliferation across projects.
Key Features
- 45U Capacity (Family: 45U / 52U / 59U): 45 rack units of usable vertical space handles a fully populated switch stack, patch panel tier, and multiple 1U appliances without overflow. If your equipment count grows post-install, the 52U and 59U variants in the Vertiv VRX line use the same footprint so a future swap doesn't require re-cabling the room.
- 24–36in Adjustable Depth: Rail depth adjusts across a 12-inch range at installation — shallow enough for wall-mount-style network gear at 24in, deep enough for most mid-tower servers at 36in. No spacer kits, no secondary order required.
- Winter White Finish: The W suffix in VRX-45U2436-W-SQM6 designates Winter White — the correct choice for clean-room, healthcare, or aesthetics-sensitive environments where a standard black rack stands out. Black variants exist in the same VRX family if finish doesn't matter.
- 3/8in Square-Hole (M6) Mounting: SQM6 denotes standard 3/8-inch square holes tapped for M6 cage nuts — the dominant mounting standard across server, networking, and power distribution hardware. Virtually all enterprise gear ships with M6 hardware, so you won't be sourcing adapters at the job site.
- #12-24 Tapped Mounting Option: The rack also supports #12-24 tapped rails, giving you compatibility with legacy or specialty gear that specifies UNC thread fasteners rather than metric cage nuts — useful in mixed-vintage equipment rooms.
- Open Frame Construction: Open-frame racks improve airflow on both sides of installed equipment, which matters in high-density thermal environments. Cable management and power strip routing are also simpler compared to enclosed cabinets — beneficial when the installation is in a controlled-access room that doesn't need a locking door.
Integration and Compatibility
The M6 square-hole rail pattern is the standard for enterprise networking and server hardware from virtually every major vendor. The dual-thread option (#12-24 and M6) means this rack accommodates both current-generation and legacy equipment without rail adapters. At 24–36in adjustable depth, the VRX-45U2436-W-SQM6 suits standard 19-inch EIA equipment. Pair with a compatible rack PDU for structured power distribution within the frame. For enclosed deployments requiring door and side-panel security, consider an enclosed cabinet variant in the Vertiv product family.
Frequently Asked Questions
Q: What does the 'W' in VRX-45U2436-W-SQM6 indicate?
A: The 'W' designates the Winter White finish. The same rack is available in Black within the VRX family if color is not a requirement.
Q: What mounting hole standard does the VRX-45U2436-W-SQM6 use?
A: The SQM6 suffix indicates 3/8-inch square holes configured for M6 cage nuts — the standard used by the vast majority of enterprise server and networking hardware. The rack also supports #12-24 tapped mounting for compatibility with legacy equipment.
Q: Can the depth be adjusted after installation?
A: The VRX series supports 24–36-inch rail depth adjustment, which is typically set at the time of installation. Verify with Vertiv documentation whether in-rack adjustment is supported without unloading the frame.
Q: Is this rack available in other heights?
A: Yes. The VRX family includes 45U, 52U, and 59U configurations. The VRX-45U2436-W-SQM6 is the 45U variant in Winter White with M6 square-hole mounting.
Q: Is this an open-frame or enclosed rack?
A: The VRX-45U2436-W-SQM6 is an open-frame rack. If your deployment requires locking doors or side panels for physical security, evaluate an enclosed cabinet variant from the Vertiv lineup.
The VRX-45U2436-W-SQM6 is a rack I'd spec specifically when finish and mounting-thread flexibility both matter on the same project. The Winter White color isn't cosmetic filler — in healthcare IT closets or clean-room network nodes, a black rack genuinely gets flagged by facilities as non-compliant with room standards. The M6 square-hole pattern (with #12-24 tapped backup) means you're not issuing a change order because one legacy appliance needs UNC threads.
Technical Highlights:
- Dual-thread rail (M6 + #12-24): Eliminates the need for thread adapters in mixed-vintage equipment rooms — one rack covers both metric and imperial hardware without a secondary kit order.
- 24–36in adjustable depth: A 12-inch adjustment range at install time accommodates everything from 1U shallow switches to full-depth 2U servers without buying a different SKU per equipment type.
- 45U / 52U / 59U family: All three height variants share the same footprint and finish, so a future capacity upgrade in the same room doesn't require repositioning floor tiles or re-running overhead cable management.
Deployment Considerations:
- Open-frame construction requires a controlled-access room or a locking cage overlay — there are no integral doors or side panels on this model to restrict physical access to installed hardware.
- Winter White finish (W suffix) is a specific variant — confirm the finish code before ordering if the project calls for standard black; the Black VRX variant carries a different suffix and is a separate SKU.
The VRX-45U2436-W-SQM6 is the right call for healthcare network closets, clean-room edge nodes, or aesthetics-sensitive corporate IT rooms where both finish standards and legacy hardware thread compatibility are real constraints — not hypothetical ones.
