Vertiv GL24WMCMS-B-SH-00-CM 12U Wall-Mount Network Enclosure
The Vertiv GL24WMCMS-B-SH-00-CM is a wall-mount enclosure from Vertiv's WM Premium line, configured as a 12U cabinet in black with a swing handle access control option and integrated cable management bar. It targets edge networking closets, IDF rooms, and security equipment installations where floor space is limited and a clean, maintainable wall-hung enclosure is the practical answer.
Overview
Vertiv's WM Premium series is a configurable enclosure platform covering 12U, 19U, and 25U heights — giving integrators a consistent mounting and management framework across small branch deployments and larger IDF buildouts. The GL24WMCMS-B-SH-00-CM lands at the 12U tier, pairing a 24-inch-wide by 32-inch-deep chassis with black finish. For the full Vertiv enclosure and infrastructure catalog, wall-mount options span multiple access and airflow configurations within this same product family.
Key Features
- Three Height Options (12U / 19U / 25U): the platform scales from a compact 24-inch-tall 12U unit to a 48-inch 25U enclosure, so you can standardize on Vertiv hardware across sites without switching vendors as density grows.
- Door Configurations — Plexi, Mesh, or Solid: Plexi front gives visual status-check without opening the door; mesh maximizes passive airflow for heat-generating switching gear; solid provides the cleanest look in public-facing or customer-visible spaces. Specify at order time for this SKU family.
- Swing Handle Access Control: the GL24WMCMS-B-SH-00-CM ships with a swing handle, the straightforward key-lock option for controlled-access closets without electronic credential overhead. Step up to SEAL Combo or SEAL Electronic if you need audit trails or badge integration on the wall-mount enclosure itself.
- Cable Management Bar Included: the CM (cable management) configuration provides a cable bar inside the chassis — keeps patch runs organized in tight wall-mount installs where cable clutter compounds quickly. Skip this option only if you are mounting a single-device installation with no horizontal cabling to manage.
- Fan Airflow Option Available: this SKU is configured without a fan (00 suffix), relying on passive convection — acceptable for low-density switch and patch installations. The same cabinet is available with integrated fan airflow for higher-heat payloads like PoE switches or compact UPS units.
- Black and Winter White Color Options: black finish suits server room and data closet environments; Winter White integrates cleanly into office hallway or lobby IDF installs where the enclosure is visible.
Integration & Compatibility
The WM Premium enclosure family is designed around standard 19-inch EIA rack units, compatible with the full range of 1U–4U network switches, patch panels, KVM units, and network infrastructure equipment. Wall-mount depth at 32 inches accommodates most 1U managed switches and 1U/2U patch panels without modification. For power distribution inside the enclosure, a vertical or horizontal PDU mounted within the rack rails provides clean power routing without occupying U-space unnecessarily. If your payload includes PoE switches or edge compute nodes running continuously, assess whether the passive-airflow (no-fan) configuration is sufficient — the fan option exists within this same WM Premium family for higher-heat payloads.
Frequently Asked Questions
Q: What U-space configurations are available in the WM Premium series that includes the GL24WMCMS-B-SH-00-CM?
A: The WM Premium series covers 12U (24-inch height), 19U (36-inch height), and 25U (48-inch height) options within the same enclosure platform.
Q: What door styles are available for this enclosure family?
A: Three door options are available: Plexi (clear acrylic for visual equipment checks), Mesh (open airflow for heat-sensitive gear), and Solid (opaque panel for cleaner appearance in public spaces).
Q: Does the GL24WMCMS-B-SH-00-CM include a fan for active cooling?
A: No — the -00- segment of the SKU indicates the no-fan (passive airflow) configuration. A fan-equipped variant is available within the same WM Premium family for higher-density or higher-heat installations.
Q: What access control options are available for this wall-mount enclosure?
A: The WM Premium series supports Swing Handle (key lock), SEAL Combo (combination lock), and SEAL Electronic (electronic credential) access control options. The GL24WMCMS-B-SH-00-CM is configured with a swing handle.
Q: What colors are available for the Vertiv WM Premium enclosures?
A: Black and Winter White finishes are offered across the WM Premium line, allowing integration into either data closet or office-visible environments.
The GL24WMCMS-B-SH-00-CM is a wall-mount enclosure I reach for on smaller edge and IDF deployments — the 12U form factor at 32-inch depth fits a standard managed switch and a 1U patch panel without pushing the wall-mount load rating, and the integrated cable management bar keeps horizontal runs clean inside a chassis where there is genuinely no room for sloppy cabling. The swing handle keeps it simple for controlled-access IT closets where you are not running electronic credential systems.
Technical Highlights:
- Three-height platform (12U / 19U / 25U): standardize procurement on one enclosure family across all your edge sites — the 12U here and a 19U at a denser location ship from the same WM Premium line with consistent rack rails and accessory compatibility.
- Door options (Plexi / Mesh / Solid): specify Mesh if you are loading this with a PoE switch running at 60–70% of rated wattage — passive convection through a solid door is marginal at sustained heat loads; Mesh buys real temperature headroom without the cost or noise of an active fan module.
- Cable management bar (CM config): critical in a 12U chassis — without it, patch cables from a 24-port panel will obscure front-panel LEDs and create a troubleshooting headache in a cabinet where you have maybe 10 inches of working space to your left and right.
Deployment Considerations:
- This SKU ships in the passive-airflow (no-fan) configuration — verify your switch's thermal spec before committing; most 1G unmanaged switches are fine, but a fully-loaded 48-port PoE+ managed switch in a sealed-door Solid variant will need either the fan module or a door swap to Mesh.
- The swing handle is a key-lock mechanism — if your facility requires electronic access audit trails at the enclosure level (SEAL Electronic), that is a different SKU in the same WM Premium family; do not assume a field retrofit is straightforward.
This enclosure is the right fit for a branch office or retail IDF closet running a single access switch and patch panel — clean, maintainable, and standardized on a Vertiv platform already present in the data center.
