Vertiv CMRX-59U24-B-SQM6 59U Open Frame Server Rack
Overview
The Vertiv CMRX-59U24-B-SQM6 is a 59U open frame rack enclosure with a 24-inch width and 24-inch depth in a black finish — a purpose-built infrastructure foundation for data centers, server rooms, network closets, and surveillance head-end installations where cable access, airflow, and vertical density all matter at once. At 59U of usable vertical space, this rack accommodates dense equipment deployments without requiring full-height floor-to-ceiling clearance, making it well suited for standard raised-floor environments and mid-height rows where overhead cable management or cooling infrastructure sits above the rack line.
Open frame construction is the deliberate choice here: no side panels and no doors mean unrestricted front, rear, and side access to mounted equipment from any angle. Technicians can route cables, swap modules, and perform maintenance without disassembling enclosure panels — a real operational advantage in high-turnover environments like network operation centers, surveillance head-ends running multiple network video recorders, and colocation rows where multiple operators share the same physical space. The CMRX-59U24-B-SQM6 (often searched as CMRX 59U24 B SQM6) belongs to the Vertiv CMR open frame rack family, engineered for commercial and enterprise data infrastructure.
Key Features
- 59U Vertical Capacity: 59 rack units of usable mounting space — enough to house a full complement of 1U and 2U servers, switches, patch panels, and storage arrays in a single footprint. That vertical density reduces floor space consumption compared to spreading equipment across multiple shorter racks, which directly lowers per-unit real estate cost in leased data center environments.
- 24-Inch Width: Standard 24-inch (EIA-310) rack width accommodates virtually all enterprise switching, server, and storage hardware without adapters or custom rails. If you are sourcing network switches or NVRs alongside this rack, standard 19-inch rackmount equipment drops straight in using the included or field-sourced rail kits.
- 24-Inch Depth: The 24-inch depth suits 1U and 2U networking gear, patch panels, and shallow-depth servers cleanly. Note that deep 1U or 2U servers — particularly those with rear-facing cable bundles — may benefit from a deeper enclosure; verify your deepest equipment's chassis dimension before ordering.
- Open Frame Construction: No panels or doors means natural convection airflow paths remain unobstructed, which helps maintain inlet temperatures on densely populated rows without forcing reliance on in-row or overhead cooling alone. For surveillance head-end deployments with always-on NVRs and encoders generating continuous heat, this passive airflow benefit is meaningful.
- Black Powder-Coat Finish: The black finish integrates cleanly into NOC environments, broadcast racks, and security operations centers where appearance consistency across rows matters. Color coding by rack or zone is a common practice in large installations — black is the neutral default that fits into any scheme.
- Vertiv CMR Platform: Part of Vertiv's CMR open frame rack line — a platform with broad accessory ecosystem support including side panels, casters, seismic anchoring kits, and cable management arms. That ecosystem means you can start open and add enclosure accessories later if your deployment requirements change without replacing the rack itself.

Integration and Compatibility
The CMRX-59U24-B-SQM6 is compatible with standard 19-inch EIA-310 rackmount equipment. Shallow-depth networking gear, patch panels, 1U/2U servers, and KVM switches all mount without modification. For security and surveillance deployments, this rack houses NVR appliances, video management servers, PoE switches, and fiber patch infrastructure in a consolidated footprint — a practical head-end build for mid-to-large camera deployments. Pair it with a rack PDU appropriate for your load to complete the power distribution layer. Side panels, blanking panels, and cable management accessories from the Vertiv CMR accessory family are field-installable if you need to transition from open frame to semi-enclosed at a later stage. When planning rack density, consult the load rating specifications from Vertiv's CMR series documentation to confirm the static and dynamic weight limits for your intended equipment mix.
For buyers evaluating physical server rack and enclosure options, the 24x24-inch footprint and 59U height position this model between compact half-height racks and full 42U or 47U tower enclosures — it is the right choice when you need significant vertical capacity but have overhead or row-height constraints that rule out a full 84-inch-plus rack.
Frequently Asked Questions
Q: What is the rack unit height of the CMRX-59U24-B-SQM6?
A: The CMRX-59U24-B-SQM6 provides 59U of usable vertical mounting space.
Q: What are the width and depth dimensions of this rack?
A: The rack is 24 inches wide and 24 inches deep, accommodating standard 19-inch EIA-310 rackmount equipment.
Q: Is the CMRX-59U24-B-SQM6 an open frame rack or a closed enclosure?
A: It is an open frame rack — no side panels or doors are included. This allows unrestricted cable access and airflow from all sides. Vertiv CMR-compatible side panels and enclosure accessories can be added separately.
Q: What finish does this rack come in?
A: The CMRX-59U24-B-SQM6 ships in a black powder-coat finish.
Q: Is this rack suitable for surveillance and security head-end installations?
A: Yes. The open frame design and 59U capacity make it practical for consolidating NVR appliances, video management servers, PoE switches, and fiber patch equipment in a single rack footprint — a common requirement for mid-to-large camera system head-ends.
Q: Can I add casters or seismic anchoring to this rack?
A: The CMRX-59U24-B-SQM6 is part of the Vertiv CMR open frame platform, which supports a range of field-installable accessories including casters and anchoring hardware. Confirm specific accessory compatibility with Vertiv's CMR accessory list before ordering.
The CMRX-59U24-B-SQM6 is a 59U open frame rack at 24 inches wide by 24 inches deep — and that 24-inch depth is the spec I want buyers to pay close attention to. It is shallower than the 29-inch and 36-inch options you will see in the CMR family, which makes it the right fit for networking-heavy rows (switches, patch panels, fiber distribution) but a tighter call for deep 1U servers with rear cable bundles or dual power supplies that extend beyond 20 inches of chassis depth. Know your deepest piece of equipment before you commit.
Technical Highlights:
- 59U Vertical Capacity: At 59U, this rack sits between the common 42U and 84U options — useful when row height, ceiling clearance, or airflow separation requirements rule out a full-height enclosure but 42U is not enough vertical space for the planned equipment count.
- 24-Inch Depth: Optimized for shallow networking gear, patch panels, and 1U aggregation switches. If your BOM includes any appliances with rear-facing cable egress exceeding the 24-inch chassis depth, plan for a rear cable bend radius that clears the rack uprights — or select a deeper CMR variant.
- Open Frame Platform: No panels means no airflow restriction and no panel removal for every cable run — a genuine time saver over the life of a dense deployment. Vertiv's CMR accessory ecosystem lets you retrofit side panels or a top cable tray without replacing the rack frame.
Deployment Considerations:
- For surveillance head-end builds housing NVRs and video management servers, confirm that your NVR chassis depth fits within 24 inches. Most 1U and 2U NVR appliances from leading manufacturers run 14 to 20 inches deep and will fit cleanly; higher-density storage servers often exceed that.
- Open frame racks in shared or public-access areas require a separate physical security strategy — locking side panels or a secure room. This rack ships without any access control hardware, so factor that into your site security design if the installation is not in a controlled server room.
The CMRX-59U24-B-SQM6 is best matched to network closet and security operations center head-end builds where the equipment mix is predominantly 1U networking gear, patch panels, and shallow NVR appliances — and where technician access speed and cable management flexibility outweigh the need for a fully enclosed cabinet.
