Vertiv CMR-45U10-W-1224 45U Open-Frame Server Rack — Winter White, 10.5" Depth
Overview
The Vertiv CMR-45U10-W-1224 is a 45U open-frame rack built for environments where airflow, accessibility, and a clean installation aesthetic matter as much as structural integrity. At 10.5 inches of usable depth in a Winter White finish, this unit fits naturally into office data closets, network operations centers, and light-industrial control rooms where black enclosures would stand out against the surrounding infrastructure. If you're speccing a rack enclosure for a mid-density deployment and need a shallow footprint without sacrificing rack unit count, the CMR-45U10-W-1224 (often searched as CMR 45U10 W 1224) is worth serious consideration.
The CMR series from Vertiv is engineered around practicality — no unnecessary panels eating into your cable management space, no proprietary mounting schemes that lock you into a single vendor's accessories. This unit ships in Winter White, making it a practical match for bright server rooms and clean-room-adjacent installations where color coordination with existing infrastructure is a real concern for facilities teams.
Key Features
- 45U Rack Height: 45 rack units gives you room for a full complement of 1U patch panels, switches, and 2U/4U appliances without stacking racks or going vertical with an oversized 59U footprint. That's the sweet spot for mid-density NOC and data-closet builds — enough capacity to consolidate a full floor's network gear in a single unit.
- 10.5" Usable Depth: Shallow 10.5-inch depth is designed for lighter network gear, patch panels, and cable management hardware rather than deep server chassis. If your deepest device is a 10-inch managed switch, this rack fits without dead air behind the equipment — tighter cable runs, less slack management headache.
- #12-24 Tapped Mounting: Standard #12-24 tapped rail holes mean you can install cage-nut-free with standard rack screws on any compliant 1U, 2U, or higher equipment. No fumbling with cage nuts on a fully loaded rack during maintenance windows — a real time saver when you're swapping gear under pressure.
- Winter White Finish: The Winter White color option isn't cosmetic padding — it's a practical spec for installations alongside white cable trays, white ceiling tiles, and bright ambient environments where a black rack reads as an eyesore in a facilities audit. Matches standard Vertiv and third-party white infrastructure accessories.
- Open-Frame Design: Without side panels or a door assembly, hot air exits the rack on all sides rather than building up in a closed enclosure. For shallow, low-heat network gear in a well-ventilated room, open-frame is almost always the right call — simpler to cable, easier to inspect, and no need to plan around blanking panels.
- CMR Series Build Quality: The CMR line from Vertiv is built to commercial-grade standards for data center and IT infrastructure environments — welded steel construction, consistent rail tolerances, and mounting geometry that holds alignment across the full 45U span without rail deflection under load.
Integration and Compatibility
The #12-24 tapped mounting pattern is one of the two dominant rack hardware standards (alongside M6 square-hole), and it's supported natively by the vast majority of 19-inch rackmount equipment from network, security, and AV vendors. If you're deploying alongside managed PoE switches, patch panels, or 1U security appliances, standard rack screws seat directly without adapters.
The CMR-45U10-W-1224 depth of 10.5 inches is purpose-matched to shallow network hardware. Before committing, verify the deepest device in your BOM — most enterprise switches run 12–17 inches, which would overhang this rack's rails. This unit is optimally paired with patch panels, cable managers, 1U network appliances, and KVM switches that fall within the 10-inch depth envelope. For deeper server or UPS deployments, consider a deeper CMR variant in the same family (12" or 16.25" depth options exist in the CMR line).
For installations requiring M6 square-hole compatibility instead of #12-24 tapped, note that this specific configuration ships with tapped rails — confirm your equipment's mounting hardware before ordering. Cage-nut rail inserts can convert tapped rails, but plan for that step in your rack accessory BOM if your gear requires it.
Frequently Asked Questions
Q: What is the exact usable depth of the CMR-45U10-W-1224?
A: The CMR-45U10-W-1224 is configured with 10.5 inches of depth. The CMR family is also available in 6", 12", and 16.25" depth variants — verify your deepest device's spec sheet before selecting a depth.
Q: Does the CMR-45U10-W-1224 use tapped or square-hole rails?
A: This configuration ships with #12-24 tapped rails, which accept standard rack screws directly without cage nuts. If your equipment requires M6 square-hole mounting, you will need cage-nut inserts or a different rail configuration.
Q: Is the CMR-45U10-W-1224 available in black?
A: The CMR-45U10-W-1224 specifically designates the Winter White finish. Black variants exist in the CMR family under separate model numbers — confirm the color suffix in the MPN when ordering.
Q: What type of equipment is the CMR-45U10-W-1224 best suited for?
A: At 10.5" depth, this rack is optimally matched to patch panels, 1U network switches, cable management hardware, and other shallow IT and security appliances. Deep server chassis or UPS units typically exceed this depth and require a deeper CMR variant.
Q: Is the CMR-45U10-W-1224 an open-frame or enclosed rack?
A: The CMR-45U10-W-1224 is an open-frame rack — no side panels or doors. This maximizes airflow and accessibility for shallow network gear but does not provide physical security enclosure or dust protection. For enclosed options, review Vertiv's VR or VRA enclosure series.
The CMR-45U10-W-1224's 10.5-inch depth is the spec that defines where this rack belongs — and where it doesn't. I see integrators overlook depth and then try to shim or overhang equipment off the back rail, which creates cable stress and rail deflection issues over time. Get this right at spec time: measure your deepest device, add 1–2 inches for connector clearance, and confirm that number is under 10.5 inches before the CMR-45U10-W-1224 lands on your BOM.
Technical Highlights:
- 45U Capacity: 45 rack units in a single open-frame unit handles a full floor's worth of shallow network gear — patch panels, managed switches, 1U security appliances — without going to a 52U or 59U frame that adds unnecessary height in low-ceiling data closets.
- #12-24 Tapped Rails: Tapped mounting eliminates cage nuts entirely, which matters on a fully loaded 45U frame where you're potentially installing or swapping 30+ devices over the rack's service life. Direct-screw installation is faster and more reliable under real-world maintenance conditions.
- Winter White Finish: Not just aesthetic — Winter White is a specified colorway that matches standard Vertiv accessory hardware and white cable management systems. Ordering a black CMR variant and then painting it is not a supported approach; specify Winter White at order time if color matching matters for your installation.
Deployment Considerations:
- Confirm every device in your BOM is within the 10.5-inch depth envelope before ordering — enterprise PoE switches frequently run 12–17 inches and will overhang the rear rail on this unit.
- Open-frame construction means no physical security or dust protection; if this rack is in a public-access corridor or dusty mechanical room, consider an enclosed Vertiv enclosure instead of the CMR series.
The CMR-45U10-W-1224 is the right call for a clean, white-finish NOC or IT data closet where the gear is shallow, the airflow is managed at the room level, and installers need direct screw-mount simplicity across a full 45U of patch panels and network appliances.
