Vertiv Cmrx 45U 24 in 36 in Black - CMRX-45U36-B-1224

Vertiv CMRX-45U36-B-1224 45U Open-Frame Rack Enclosure

Overview

The Vertiv CMRX-45U36-B-1224 is a 45U, 24-inch-wide, 36-inch-deep black rack enclosure from Vertiv's CMRX series — built for data centers, security equipment rooms, and enterprise infrastructure deployments where structured, high-density equipment mounting is non-negotiable. If you're racking servers, NVRs, patch panels, network switches, or access control infrastructure in a permanent installation, this is the chassis you size the room around. At 45U, it gives you enough vertical real estate to consolidate multiple equipment tiers without stacking separate racks — a meaningful operational difference when you're managing cable runs and power distribution across a large installation.

The black finish (denoted by the "-B" in the model number CMRX-45U36-B-1224) is the standard choice for most modern equipment rooms and data centers. The 36-inch depth accommodates deep 1U and 2U servers, full-depth UPS units, and high-port-count switch chassis without forced angling or shelf workarounds — a spec worth verifying before ordering if your deepest piece of gear is borderline. The 24-inch width is the industry-standard EIA-310 cabinet width, meaning virtually all rackmount equipment will fit without adapter plates.

Key Features

• 45U Vertical Capacity: Forty-five rack units of usable mounting space means you can consolidate servers, storage, network gear, and security infrastructure into a single enclosure rather than spreading across multiple smaller frames — simplifying cable management and reducing floor space consumed per unit of equipment.
• 36-Inch Depth: The 36" interior depth accommodates full-depth enterprise hardware — deep 2U servers, tower-to-rack converted appliances, and UPS units — without the shelf adaptors and depth extenders that add cost and complexity in shallower frames. Verify your deepest equipment's rail-to-rear clearance before ordering.
• 24-Inch Standard Width: EIA-310 standard 24" width ensures compatibility with virtually all rackmount equipment and standard rack PDUs. No adapter plates needed for mainstream enterprise gear.
• Dual Mounting Standards — #12-24 Tapped and 3/8" Square (M6): Supporting both the legacy #12-24 tapped rail standard and the M6 square-hole (3/8" sq.) standard means you can mount both older North American equipment and modern metric-threaded hardware in the same enclosure without rail swaps. The "Clear" option referenced in the spec data indicates additional mounting rail flexibility depending on configuration ordered.
• CMRX Series Build Quality: Vertiv's CMRX line is designed for permanent, high-load infrastructure installations — not relocatable or light-duty applications. The enclosure is intended to carry full equipment loads across its rated rack unit height without frame flex that would bind sliding rails or stress cable management arms.
• Black Finish for Standard Equipment Room Integration: The "-B" (Black) designation matches the visual standard for most modern data centers and equipment rooms. Vertiv also offers this frame in Winter White for legacy or specific facility aesthetic requirements — verify the color suffix when ordering to avoid a freight return on a large chassis.

Integration & Compatibility

The CMRX-45U36-B-1224 is compatible with standard EIA-310 rackmount equipment across servers, network video recorders, PoE and managed network switches, patch panels, and security appliances. The dual mounting rail standard (#12-24 tapped and M6 square-hole) covers both legacy North American equipment and current-generation enterprise hardware. If you're building a IP camera infrastructure backbone — NVRs, PoE switches, VMS servers — this rack provides the physical consolidation point.

For power distribution inside the enclosure, standard 1U and 2U rack PDUs from Vertiv and third-party vendors mount to the #12-24 or M6 rails without modification. Cable management accessories — horizontal and vertical wire managers — should be specified separately and confirmed for CMRX rail spacing compatibility before ordering. Review the rack enclosures category for complementary accessories and additional Vertiv rack configurations.

This enclosure is also a natural fit for access control panel and infrastructure rack deployments, where consolidating controllers, power supplies, and patch connections into a single secure enclosure is a common requirement. The 45U height provides ample space for mixed security and IT infrastructure in a shared equipment room.

Frequently Asked Questions

Q: What is the exact usable interior depth of the CMRX-45U36-B-1224?

A: The CMRX-45U36-B-1224 has a 36-inch nominal depth. Verify usable rail-to-rail and rail-to-rear clearance against your deepest equipment's specifications before ordering, as interior usable depth will be slightly less than the nominal frame depth due to rail and door/panel thickness.

Q: Does the CMRX-45U36-B-1224 support M6 square-hole rail mounting?

A: Yes. The CMRX-45U36-B-1224 supports both #12-24 tapped and 3/8" square (M6) rail mounting standards, covering the majority of current enterprise rackmount equipment without requiring adapter hardware.

Q: Is the CMRX-45U36-B-1224 available in other heights or depths?

A: The CMRX series is available in multiple heights (45U, 52U, 59U) and multiple depth configurations (10.5", 16.25", 24", 30", 36"). The CMRX-45U36-B-1224 specifically designates 45U height and 36" depth in black. Order the correct SKU for your height and depth requirement — these are not field-adjustable after the fact.

Q: Is the CMRX-45U36-B-1224 available in colors other than black?

A: The CMRX series is also available in Winter White. The "-B" suffix in CMRX-45U36-B-1224 designates the Black finish. Confirm the color suffix on your order — a color mismatch on a large freight item is a costly return.

Q: What type of equipment is the CMRX-45U36-B-1224 designed for?

A: The CMRX-45U36-B-1224 is a commercial-grade rack enclosure designed for permanent installation of servers, NVRs, network switches, UPS units, patch panels, security appliances, and access control infrastructure in data centers, equipment rooms, and security operations environments.

Q: Does the CMRX-45U36-B-1224 include cable management accessories?

A: Cable management accessories (horizontal and vertical wire managers, cable management arms) are not confirmed as included in the base enclosure and should be specified and ordered separately. Verify CMRX rail spacing compatibility for any third-party cable management accessories before procurement.

The spec I focus on immediately with the CMRX-45U36-B-1224 is the dual rail standard — #12-24 tapped and M6 square-hole in a single enclosure. In mixed-vintage equipment rooms, that saves real time and money: you're not ordering conversion hardware or swapping rail sets when a new server with metric-thread mounting lands next to legacy North American gear.

Technical Highlights:

• 45U Height: Forty-five rack units in a single chassis is enough vertical space to house a full NVR stack, PoE switching tier, and patch infrastructure — keeping security and IT infrastructure consolidated without spilling into a second enclosure and adding cable run complexity.
• 36-Inch Depth: The 36" depth spec is what separates this enclosure from mid-depth frames — it's the number you need for full-depth 2U servers and rack-mount UPS units. Anything shallower and you're problem-solving around your deepest hardware before the rack is even populated.
• Dual Mounting Standard (#12-24 / M6): Supporting both tapped and square-hole rail standards in one enclosure reduces procurement friction in environments where equipment comes from multiple generations and vendors — no per-device rail adapters needed.

Deployment Considerations:

• The 36-inch nominal depth is a frame measurement — usable rail-to-rear clearance will be somewhat less. Measure your deepest equipment's actual depth including cable egress before committing to this enclosure in tight floor plan layouts.
• Cable management accessories, blanking panels, and PDUs are not confirmed included. Budget and specify these separately; a fully-loaded 45U enclosure without vertical cable managers becomes a maintenance problem quickly at scale.

The CMRX-45U36-B-1224 is the right specification for a permanent physical security or enterprise IT equipment room where you're consolidating 30–45U worth of NVR, switching, and server infrastructure into a single managed footprint — particularly where mixed-vintage equipment demands dual-standard rail flexibility.
