Vertiv Cmrx 45U 24 in 24 in White - CMRX-45U24-W-1224

Vertiv CMRX-45U24-W-1224 45U Open-Frame Rack — 24in Wide, Winter White

The Vertiv CMRX-45U24-W-1224 is a 45U open-frame rack engineered for data center and network environments where airflow access and flexible equipment mounting matter most. Part of Vertiv's CMRX series — a line with a proven track record in structured cabling, server, and network deployments — this unit delivers a 45U usable height in a 24-inch-wide, 24-inch-deep footprint and ships in Winter White to suit environments where a lighter visual profile is preferred or required. Vertiv (formerly Liebert/Emerson) brings decades of data center infrastructure expertise to this product line, and the CMRX series reflects that heritage in its mounting flexibility and build consistency.

Key Features

• 45U Usable Height: Provides space for up to 45 rack units of equipment in a single frame, reducing floor footprint while maximizing vertical density in a data center row or network closet.
• 24-Inch Width: Standard 24-inch rack width accommodates EIA-310-compliant equipment, keeping your existing hardware investment compatible without adapters or custom hardware.
• 24-Inch Depth: The 24-inch depth suits switches, patch panels, and 1U–2U servers with shorter chassis, making this configuration practical for intermediate distribution frames (IDFs) and edge deployments.
• Winter White Finish: The -W suffix designates Winter White, a practical choice for lab environments, clean rooms, or facilities where rack color is coordinated with room standards or documentation photography.
• Three Mounting Hole Patterns — #12-24, 3/8in Sq. (M6), and Clear: Supporting #12-24 tapped, 3/8-inch square (M6), and clear (unthreaded) patterns means installers can use standard cage nuts, pre-tapped fasteners, or clearance mounting without drilling. This eliminates the need for adapter strips across mixed-vendor deployments and reduces installation time measurably.
• Open-Frame Construction: The absence of side panels and doors promotes unrestricted airflow from any direction — front-to-back, side-to-side — allowing passive cooling strategies or integration with hot-aisle/cold-aisle containment without modification.
• CMRX Family Scalability: The CMRX series spans 45U, 52U, and 59U heights and depth options from 10.5in through 36in, so this unit can be standardized alongside taller or deeper siblings as deployments grow, keeping cable management and mounting hardware consistent across racks.

Integration & Compatibility

The CMRX-45U24-W-1224 is built around EIA-310 rack standards, which means virtually all rackmount server, networking, storage, and rack power distribution hardware manufactured to that standard will mount without modification. The three-pattern mounting column — #12-24 tapped, M6 square, and clear — covers the full range of fastener approaches used across major hardware vendors, so mixed-vendor deployments do not require a single standardized fastener type. For rack accessories such as brush panels, blanking panels, and horizontal cable managers, the 24-inch width is the industry baseline, giving you the widest selection of compatible accessories. The open-frame construction integrates directly into hot-aisle/cold-aisle containment systems that rely on blanking panels and contained rows. Pair this unit with complementary server racks and enclosures from the same series where enclosed cabinets are required in adjacent rows, maintaining consistent rail and mounting standards throughout. For broader data center infrastructure planning — including power, cooling, and structured cabling — the CMRX fits within a Vertiv-standardized rack strategy that simplifies procurement and ongoing support.

Frequently Asked Questions

Q: What is the height of the CMRX-45U24-W-1224?

A: The CMRX-45U24-W-1224 is 45U tall. The “45U” in the model number directly indicates the usable rack unit height of this specific configuration.

Q: What color is the CMRX-45U24-W-1224?

A: This unit ships in Winter White, as indicated by the “-W” suffix in the model number. The CMRX series is also available in Black for environments where a darker finish is preferred.

Q: What mounting hole patterns does the CMRX-45U24-W-1224 support?

A: The rack supports three mounting patterns: #12-24 tapped, 3/8-inch square (M6), and Clear (unthreaded). This gives installers the flexibility to use pre-tapped fasteners, cage nuts, or clearance hardware depending on the equipment being mounted.

Q: What is the depth of the CMRX-45U24-W-1224?

A: The depth of this configuration is 24 inches, suited for shorter-chassis equipment such as patch panels, switches, and compact 1U servers commonly deployed in IDF closets and edge locations.

Q: Is the CMRX-45U24-W-1224 compatible with standard EIA rackmount equipment?

A: Yes. The CMRX-45U24-W-1224 is built to EIA-310 rack standards at 24 inches wide, so any rackmount hardware designed to that standard — servers, networking gear, KVM switches, patch panels, and power distribution units — will mount without modification.

Karl Wilson

I reach for the CMRX-45U24-W-1224 when a project calls for a 45U open-frame solution in a 24-inch-wide, 24-inch-deep format and the environment calls for Winter White. The detail that matters most in the field is the triple mounting pattern — #12-24, M6, and clear — because mixed-vendor deployments are the norm, not the exception, and stopping mid-install to source adapter strips or re-tap columns is a real time cost that this rack eliminates.

Technical Highlights:

• 45U Height: Fits a full complement of 1U patch panels, switches, and servers — typical IDF build-outs run 12–18U of active gear, leaving substantial headroom for growth without rack replacement.
• 24in x 24in Footprint: The 24-inch depth avoids the floor space penalty of a 30- or 36-inch-deep frame when the installed equipment chassis does not require that clearance — the right size saves real square footage in tight IDF rooms.
• Three Mounting Patterns: #12-24 tapped, 3/8in sq. (M6), and clear coverage eliminates the single-fastener-type constraint — a measurable advantage when hardware from three or more vendors is going into the same rack.

Deployment Considerations:

• Open-frame racks require blanking panels at unused rack units to maintain airflow discipline in contained hot-aisle/cold-aisle rows — budget approximately 20–25 1U blanking panels for a half-populated 45U frame at time of order.
• The 24-inch depth is well-matched to networking and cabling gear but may be insufficient for full-depth 2U servers with rear PSU clearance requirements — verify chassis depth against the 24-inch rail-to-rail spec before committing this model to a compute-dense row.

This configuration is best positioned for IDF closets, structured cabling rooms, and edge network deployments where the Winter White finish coordinates with the facility environment and the 24-inch depth matches the shorter-chassis profile of the installed switching and patching hardware.
