Vertiv Cmrx 45U 24 in 24 in White - CMRX-45U24-W-SQM6

Vertiv CMRX-45U24-W-SQM6 45U Open-Frame Rack — Winter White, 24-Inch Depth

The Vertiv CMRX-45U24-W-SQM6 is a 45U open-frame rack enclosure finished in Winter White, built for structured equipment deployments where accessibility, cable management, and hardware organization are the primary concerns. If your installation spec calls for a 24-inch depth footprint in a Winter White finish with M6 square-hole mounting rails, this is the unit to order — the finish and rail type are both configuration-specific and not field-swappable after purchase.

Overview

Vertiv's Vertiv rack infrastructure line covers a range of heights and depths in the CMRX family. The CMRX-45U24-W-SQM6 occupies a mid-to-large footprint in the lineup: 45U of usable rack space at a 24-inch depth — a common target for open-frame rack deployments in equipment rooms, server closets, and structured cabling environments where front-and-rear access without door panels is preferred. The Winter White color suits environments where aesthetics matter, such as retail back-offices, clean-room adjacent spaces, or facilities with white-finish standardization.

Key Features

• 45U Height: Provides substantial vertical real estate — enough to house a full stack of 1U switches, patch panels, and servers without requiring a second rack in most mid-size deployments. The CMRX family also offers 52U and 59U variants if your equipment inventory is expanding.
• 24-Inch Depth: Fits standard 1U and 2U networking and security appliances without the overrun that comes with deeper cabinets. The CMRX-45U24-W-SQM6's 24-inch depth is well-matched to PoE switches, patch panels, and NVR appliances that don't require the extra clearance of 30- or 36-inch-depth enclosures.
• 3/8-Inch Square-Hole (M6) Mounting Rails: The SQM6 suffix designates square-hole M6 rail threading — the current standard for cage-nut-based rack mounting. Virtually all modern 19-inch rackmount equipment ships with M6 cage nuts or M6-compatible hardware, so you won't need adapters for contemporary installs. Confirm your equipment list before ordering if you have legacy #12-24 tapped-hole gear, which requires a different rail configuration.
• Winter White Finish: The -W- in the part number designates Winter White — a specific factory finish, not a field-applied coating. If your facility or rack row has a Black finish standard, order the Black variant; mismatched finishes in visible equipment rooms are a common post-install regret.
• Open-Frame Architecture: Without side panels or doors, airflow is unrestricted on all sides. This is an advantage in high-density or poorly-air-conditioned spaces where enclosed cabinets trap heat, and a liability in environments where dust, physical access control, or cable concealment are requirements.

Integration and Compatibility

The CMRX-45U24-W-SQM6 accepts standard 19-inch EIA-310 rackmount equipment. The M6 square-hole rail pattern is compatible with cage-nut hardware supplied by virtually all major equipment vendors. This rack is part of Vertiv's broader Vertiv infrastructure catalog, which includes complementary power distribution units (PDUs), cable management arms, and blanking panels sized for the CMRX frame.

Frequently Asked Questions

Q: What is the rail mounting type on the CMRX-45U24-W-SQM6?

A: The CMRX-45U24-W-SQM6 uses 3/8-inch square-hole M6 rails (designated by the SQM6 suffix). This is the current standard cage-nut pattern compatible with modern 19-inch rackmount equipment. It is not a #12-24 tapped-hole configuration.

Q: Is the CMRX-45U24-W-SQM6 available in Black?

A: The -W- in the part number designates Winter White. A Black variant exists in the CMRX family under a separate model number. The finish is factory-applied and cannot be changed post-purchase.

Q: What depth is the CMRX-45U24-W-SQM6?

A: This configuration is 24 inches deep. The CMRX family also offers 10.5, 16.25, 30, and 36-inch depth options under separate SKUs.

Q: Can I use this rack for network switches and NVR appliances?

A: Yes — the 24-inch depth and 45U height accommodate standard 1U and 2U networking and security appliances. Confirm equipment depth against the 24-inch internal clearance before ordering deep chassis units.

Q: Does the CMRX-45U24-W-SQM6 include side panels or doors?

A: The CMRX is an open-frame rack. Side panels and doors are not included and would need to be ordered separately if physical access control or dust protection is required.

The CMRX-45U24-W-SQM6 is a straightforward infrastructure choice, but the details matter: the SQM6 suffix tells you exactly what you're getting — 3/8-inch square-hole M6 rails, not the older #12-24 tapped pattern. That distinction drives cage-nut selection for every piece of equipment you hang in it, so it's worth confirming before your install crew shows up with the wrong hardware.

Technical Highlights:

• 45U Capacity: Enough vertical space to house a full security stack — NVR, PoE switches, patch panels, and access control panels — without splitting across two racks in most mid-size deployments.
• 24-Inch Depth: The sweet spot for security and networking equipment; deep enough for 1U/2U appliances, shallow enough to fit in equipment closets where a 36-inch-deep cabinet won't clear the door frame.
• M6 Square-Hole Rails: The SQM6 designation means standard cage-nut compatibility with modern equipment — no rail adapters needed for current-generation switches, NVRs, or servers.

Deployment Considerations:

• Open-frame means no door lock and no dust barrier — if this rack is in a public-access or high-particulate environment, plan for an enclosure kit or a different product entirely.
• The Winter White finish is factory-applied; if your site has a Black rack standard, order the correct color variant up front — repainting or mixing finishes in a visible equipment room is a problem you don't want to solve after delivery.

This rack is a practical fit for equipment rooms, security operations centers, and structured cabling closets where technician access frequency is high and the open-frame format accelerates installs and cable runs — not for unsecured or public-facing spaces.
