Vertiv Cmrx 45U 24 in 16.25 in White - CMRX-45U16-W-1224

Vertiv CMRX-45U16-W-1224 45U Open-Frame Rack Cabinet — Winter White

Overview

The Vertiv CMRX-45U16-W-1224 is a 45U rack enclosure finished in Winter White, with a nominal 16.25-inch usable depth — a configuration commonly deployed in structured cabling rooms, broadcast environments, and clean-room data closets where standard black cabinetry is aesthetically or contractually out of spec. If you are sourcing within the broader Vertiv rack and power infrastructure catalog, the CMRX line covers multiple height and depth combinations from the same mounting standard.

The CMRX-45U16-W-1224 (often searched as CMRX 45U16 W 1224) ships in a 45U configuration, offering substantial vertical real estate for dense patch, switching, or AV gear while keeping the footprint shallow at 16.25 inches of usable depth — practical when clearance behind the rack is limited or when equipment is predominantly 1U switching and patch panels rather than deep server chassis.

Key Features

• 45U Vertical Capacity: 45 rack units accommodate a full complement of 1U switches, patch panels, and AV or security appliances — enough headroom for a complete IDF or secondary equipment closet build without requiring a taller 52U or 59U unit.
• 16.25-Inch Usable Depth: Shallow-depth design fits in space-constrained rooms and telecom closets where a full 24- or 30-inch deep cabinet cannot be positioned without blocking egress or conflicting with raised-floor tiles. Right-size the depth to your actual gear rather than buying excess cabinet.
• Winter White Finish: The white powder-coat finish suits environments — broadcast control rooms, healthcare IT closets, education AV racks — where visual standards or interior design requirements preclude standard black enclosures. Color is consistent across the CMRX family for multi-rack deployments.
• Dual Mounting Standard (#12-24 and M6): Supporting both #12-24 tapped rails and 3/8-inch square (M6) cage-nut rails means you are not locked into one equipment ecosystem. Legacy North American gear with #12-24 screws mounts directly; modern EIA-standard equipment using M6 cage nuts drops in without adapters — a practical advantage in mixed-vintage installations common in network cabinet and rack deployments.
• Multiple Configuration Options in Family: The CMRX series spans 45U, 52U, and 59U heights, and depths from 10.5 inches through 36 inches — so if this specific depth does not fit your stack, a sibling SKU in the same family maintains identical rail and finish standards. Review your data center infrastructure depth requirements before ordering.

Integration and Compatibility

The dual-rail mounting standard (both #12-24 tapped and M6 square-hole) ensures compatibility with the widest range of rackmount equipment from network switches and network video recorders to patch panels and KVM units. Confirm your equipment's rail depth requirement against the 16.25-inch usable depth before specifying — shallow-depth racks are not suitable for full-depth servers or UPS units that require 28 inches or more of clearance.

Frequently Asked Questions

Q: What mounting rail standards does the CMRX-45U16-W-1224 support?

A: The CMRX-45U16-W-1224 supports both #12-24 tapped rails (common on legacy North American equipment) and 3/8-inch square (M6) cage-nut rails (EIA standard for modern switching and server gear). A clear/unthreaded option is also noted in the spec data.

Q: Is 16.25 inches deep enough for standard 1U network switches?

A: Most 1U access switches (Cisco Catalyst 1000/2960, Netgear ProSAFE, and similar) have chassis depths of 9 to 14 inches and fit comfortably in a 16.25-inch rack. Full-depth enterprise switches or deep chassis servers typically require 24 to 30 inches — use a deeper CMRX variant for those.

Q: What other height options exist in the CMRX family?

A: The CMRX line includes 45U, 52U, and 59U height variants. If 45U is insufficient for your build, a 52U or 59U model in the same series maintains the same rail standard and finish.

Q: Can the CMRX-45U16-W-1224 be ordered in black instead of white?

A: Yes. The CMRX family is available in both black and Winter White finishes. The '-W-' designation in the model number identifies the white configuration — select the equivalent black SKU if your environment requires standard black cabinetry.

Q: What depth variants are available if 16.25 inches is not sufficient?

A: The CMRX series covers 10.5, 16.25, 24, 30, and 36-inch depth options. Choose based on the deepest piece of equipment you intend to mount — allow at least 2 to 4 inches of rear clearance beyond the equipment chassis for cable management and airflow.

Karl Wilson

The CMRX-45U16-W-1224 is a product I get asked about most often in two specific contexts: healthcare IT closets where facilities management mandates white or light-grey enclosures, and broadcast infrastructure rooms where rack aesthetics are part of the room design spec. The 16.25-inch depth is the differentiating dimension here — it tells you exactly what this cabinet is and is not for. At that depth, you are housing shallow-depth switching, patch panels, AV matrix units, and security appliances. You are not housing blade chassis or dense UPS arrays.

Technical Highlights:

• Dual Rail Standard (#12-24 + M6): Supporting both tapped and cage-nut rails in the same enclosure is genuinely useful in retrofit scenarios where you are mixing a legacy access switch with a new managed PoE switch — no adapter plates, no rail swaps mid-project.
• 45U Height with Shallow Depth: The 45U / 16.25-inch combination gives you dense vertical capacity without the floor-space footprint of a full-depth 45U cabinet. In a 10x10 foot IDF with fire-door clearance requirements, that 8 inches of saved depth can be the difference between compliant and non-compliant positioning.
• Winter White Powder Coat: The finish is consistent across the CMRX family width, so if you are deploying multiple cabinets side-by-side in an open-plan environment, you get visual uniformity across a mixed-depth row without sourcing from multiple vendors.

Deployment Considerations:

• Confirm every piece of equipment's chassis depth before specifying this cabinet. The 16.25-inch figure is the usable rail-to-rail depth — include rear cable management and PDU clearance in your calculation; in practice, equipment should be no deeper than 12 to 13 inches in this enclosure.
• The CMRX-45U16-W-1224 spec page lists depth as a family range (10.5 through 36 inches) — this SKU's 16.25-inch figure is confirmed by the model number suffix ('16'), but verify with the Vertiv product configurator if your procurement process requires a written spec sheet tied to this specific SKU before purchase order.

This cabinet is well-matched to a structured cabling IDF in a healthcare wing, education building, or broadcast studio where shallow-depth, white-finish enclosures are specified by the AV or facilities design team — not a general-purpose server room cabinet, and should not be quoted as one.
