Vertiv CMR-45U06-W-SQM6 45U Open Frame Rack — Winter White, 6" Depth, M6 Square-Hole
Overview
The Vertiv CMR-45U06-W-SQM6 is a 45U open frame rack designed for environments where space efficiency and hardware accessibility take priority over enclosed cabinet security. The 6-inch depth profile makes it the right fit for shallow-footprint deployments — wall-adjacent rows, narrow IDF closets, or staging areas where full-depth enclosures would block aisle or access. The Winter White finish suits cleanroom, lab, or retail back-of-house environments where black racks would stand out visually. If you are browsing the Vertiv rack and enclosure line, this model sits at the shallow end of the CMR family depth range.
The CMR-45U06-W-SQM6 (often searched as CMR 45U06 W SQM6) ships in the M6 square-hole mounting configuration — the current standard for cage-nut rail systems used across most modern server, switch, and patch panel hardware. This means you can populate it directly with standard EIA-310 rackmount equipment without adapters. The 3/8" square hole pattern accepts standard M6 cage nuts, keeping your hardware sourcing straightforward across mixed-vendor environments.
Key Features
- 45U Capacity: 45 rack units of vertical space accommodates a fully loaded IDF stack — patch panels, switches, power distribution, and cable managers — without requiring a full-height 52U or 59U enclosure if your equipment count doesn't justify it. Right-size the rack to the stack, not the room.
- 6-Inch Depth: At 6 inches deep, this frame is built for passive or low-depth hardware — patch panels, fiber management, cable routing guides, and 1U/2U switches. It will not fit most 1U servers or deep PDUs; if your hardware is deeper than 5 inches, step up to the 10.5" or 12" depth variants in the CMR family.
- M6 Square-Hole Rail (3/8" sq.): The SQM6 designation means 3/8-inch square holes on M6-threaded cage nut spacing — the dominant standard in enterprise networking hardware. No round-hole drilling, no proprietary tooling. Standard M6 cage nuts drop in and your equipment mounts cleanly.
- Winter White Finish: Purpose-specified for environments where aesthetics matter — lab spaces, healthcare IT rooms, retail deployments, or any facility where the rack is visible outside a locked server room. Matches standard white ceiling tile and wall finishes better than black powder coat.
- Open Frame Construction: No doors, no side panels — full 360-degree access to cabling, ports, and hardware at any time. Ideal for network switch and patch panel builds where technicians need frequent access from multiple angles. Not appropriate where physical security of the rack contents is required.
Integration and Compatibility
The CMR-45U06-W-SQM6 follows EIA-310 rack unit spacing, making it compatible with standard 19-inch rackmount equipment across networking, power and UPS, and low-voltage infrastructure categories. The M6 square-hole rail accepts standard cage nuts available from any structured cabling supplier. For planning your rack build, review our rackmount accessories category for compatible cable managers, blanking panels, and power strips. Note that at 6 inches of depth, this frame is purpose-built for shallow passive hardware — verify your deepest component's mounting depth before specifying this model over a deeper CMR variant.
Frequently Asked Questions
Q: What is the mounting hole type on the CMR-45U06-W-SQM6?
A: The CMR-45U06-W-SQM6 uses 3/8-inch square holes on M6 cage nut spacing — the SQM6 designation in the model number confirms this. Standard M6 cage nuts are compatible; no adapters required for EIA-310-compliant equipment.
Q: Is the CMR-45U06-W-SQM6 available in black?
A: The CMR-45U06-W-SQM6 is the Winter White variant of the CMR family. The same CMR line is available in black — check the CMR family for the equivalent black model if finish matching is required for your environment.
Q: What hardware fits in a 6-inch depth open frame rack?
A: The 6-inch depth is suited for shallow passive hardware: patch panels, fiber management trays, cable routing guides, and thin 1U networking switches with front-facing ports. Most 1U servers, deep PDUs, and appliances with rear port depth exceeding 5 inches will not fit. Always verify the mounting depth of your deepest component before specifying this model.
Q: Can the CMR-45U06-W-SQM6 be configured as a different height?
A: The CMR family includes 45U, 52U, and 59U height options. The CMR-45U06-W-SQM6 is specifically the 45U configuration. If you need more vertical space, look at the 52U or 59U variants in the CMR line with the same 6-inch depth and M6 square-hole spec.
Q: Does this rack require assembly?
A: Open frame racks in the CMR family are typically shipped in flat-pack form and require on-site assembly. Confirm assembly requirements and included hardware with your order documentation, as package contents were not specified in the available evidence.
The CMR-45U06-W-SQM6 is one of those SKUs that integrators order specifically because of the SQM6 suffix — the M6 square-hole rail spec eliminates the cage-nut compatibility conversation entirely on mixed-vendor builds. At 6 inches of depth and 45U of vertical space, this is purpose-built for IDF closets or wall-adjacent rows that need a structured patch panel and switch stack without committing to a full-depth enclosure footprint.
Technical Highlights:
- M6 Square-Hole Rails (3/8" sq.): SQM6 means every standard EIA-310 component with M6 cage nuts mounts without adapters — cuts installation time on multi-vendor builds and eliminates sourcing surprises on-site.
- 6" Depth Profile: Keeps the rack footprint minimal in constrained spaces. This depth tier is the right call for passive cabling infrastructure — patch panels, fiber trays, cable managers — not active compute with rear-port clearance requirements.
- Winter White Finish: The W designation means this frame is specified for visibility-sensitive environments. In healthcare IT rooms, retail back-of-house, or lab builds where aesthetics are reviewed alongside function, the white finish integrates cleanly rather than contrasting against light-colored surroundings.
Deployment Considerations:
- Verify every component's mounting depth against the 6-inch frame before the hardware ships to site. A single deep switch or PDU that doesn't fit will stall the build — the CMR family offers 10.5", 12", and 16.25" depth variants for mixed or deeper hardware stacks.
- Open frame means no physical access control on the rack contents. If the installation environment has even moderate foot traffic or shared-space concerns, specify a locking enclosure instead — the open frame design trades physical security for accessibility.
The CMR-45U06-W-SQM6 is the right call for a cleanroom or healthcare IT room IDF build where the rack is visible, the hardware is shallow passive infrastructure, and the M6 square-hole standard needs to be locked in from day one.
