Vertiv GL48WMCMS-B-SH-00-00 25U Wall-Mount Network Enclosure
Overview
The Vertiv GL48WMCMS-B-SH-00-00 is a 25U wall-mount cabinet built for structured cabling, edge networking, and small-footprint IT deployments where floor space is constrained but rack density still matters. At 24 inches wide and 32 inches deep, this enclosure provides genuine 1U-to-25U usable depth — enough to house patch panels, small switches, UPS units, and associated cabling infrastructure without committing to a full-size floor cabinet. This specific SKU ships in black with a swing-handle door and no factory-installed fan or cable management bar, giving installers a clean starting point to configure airflow and routing to match the actual load.
The Vertiv wall-mount enclosure lineup covers three height classes — 24" (12U), 36" (19U), and 48" (25U) — so if your rough-in space is tighter than 48 inches of wall height, the GL48WMCMS-B-SH-00-00 sits at the top of the family. Buyers specifying the smaller footprints should confirm clearance above and below for airflow before ordering the 25U variant.
Key Features
- 25U Capacity in a Wall-Mount Form Factor: Twenty-five rack units on the wall means you can consolidate a full IDF closet's worth of switching, patching, and power distribution without a floor footprint. Useful in retail back-offices, school MDF/IDF rooms, and warehouse edge nodes where square footage carries a premium.
- 24" × 32" Interior (W × D): The 32-inch depth accommodates standard 1U switches and patch panels without the cable-routing compromises that shallow-depth wall cabinets force. Most enterprise-class access switches and 24-port patch panels fit without modification.
- Swing-Handle Door: The swing-handle latch (this SKU's access control configuration) provides tool-free front access — no key fumble during cable pulls or equipment swaps. For environments requiring keyed or electronic access, the GL48WMCMS family also supports SEAL Combo and SEAL Electronic lock options on alternate SKUs.
- Door Style Flexibility — Plexi, Mesh, or Solid: This SKU's door configuration is defined at order; the platform supports plexi (visibility without opening), mesh (passive airflow), and solid (physical security, no visibility). Choose mesh if passive convection is your primary thermal strategy; solid if the cabinet is in a public-facing area.
- Airflow-Ready Architecture: The base SKU ships with no fan installed (the -00- airflow selector). If your load runs hot — dense patch fields, PoE midspans, or compact UPS units — the factory fan option is available on alternate SKUs. Planning airflow before the cabinet goes on the wall is significantly easier than retrofitting.
- Cable Management Options: Ships without a cable management bar (the trailing -00 in the part number). Optional Cable Bar and Clear configurations are available across the GL48WMCMS family. If you're running structured network enclosures with high patch-panel port counts, spec the cable bar at the time of order rather than improvising with aftermarket solutions.
- Color: Black: The -B- in the SKU designates black finish, which blends into server room and IDF environments without the visual noise of lighter enclosures. Winter White is available on alternate SKUs for deployments in clinical or office environments where aesthetics matter.
Integration & Compatibility
The GL48WMCMS-B-SH-00-00 accepts standard 19-inch EIA rack-mount equipment. Compatible with the full range of patch panels, managed switches, 1U UPS units, and fiber enclosures that conform to EIA-310 mounting standards. Wall-blocking and structural load ratings should be confirmed against the installation surface — drywall-only installations require blocking or a structural backing panel rated for the cabinet's populated weight. Consult the Vertiv installation guide for torque specs and anchor requirements before commissioning.
For installations pairing this cabinet with active surveillance or access control infrastructure, it integrates cleanly alongside PoE switches and patch panels, serving as the central distribution point for structured cabling runs from IP cameras, readers, and door controllers.
Frequently Asked Questions
Q: What is the rack unit capacity of the GL48WMCMS-B-SH-00-00?
A: This specific SKU is the 25U variant (48-inch height), 24 inches wide and 32 inches deep. The GL48WMCMS family also includes 12U (24-inch) and 19U (36-inch) configurations in separate SKUs.
Q: Does the GL48WMCMS-B-SH-00-00 come with a fan installed?
A: No. The -00- airflow segment of this SKU designates no factory-installed fan. If thermal management is required for your equipment load, specify the fan-equipped variant within the GL48WMCMS family at time of order.
Q: What type of door lock does this cabinet use?
A: The GL48WMCMS-B-SH-00-00 uses a swing-handle latch (designated by the -SH- in the part number). The family also supports SEAL Combo and SEAL Electronic access control on alternate configurations.
Q: Is cable management included with the GL48WMCMS-B-SH-00-00?
A: No cable management hardware is included in this base configuration (the trailing -00 in the SKU). Cable Bar and Clear cable management options are available on other SKUs within the same product family.
Q: What door style ships with the GL48WMCMS-B-SH-00-00?
A: Door style is a configuration option within the GL48WMCMS platform — available choices are Plexi, Mesh, and Solid. Confirm the door type for this specific SKU with your order documentation, as the part number suffix does not encode door style explicitly.
Q: Can this enclosure be wall-mounted on standard drywall?
A: Drywall-only mounting is generally not sufficient for a loaded 25U cabinet. Structural backing, blocking, or a wall-stud anchor pattern rated for the populated cabinet weight is required. Follow Vertiv's installation documentation for anchor type and torque specifications.
The GL48WMCMS-B-SH-00-00 is a workhorse IDF cabinet — 25U of usable depth in a 24"×32" wall-mount footprint, shipped in black with a swing-handle door and no fan or cable management bar pre-installed. That last point is intentional: this is a base configuration, and the right call is to spec your airflow and cable routing once you know the actual equipment load, not to pay for factory options you may not need.
Technical Highlights:
- 25U / 48" Wall-Mount Height: Tops the GL48WMCMS height range — fits a full IDF's worth of switching and patching on the wall without floor-cabinet cost or footprint.
- Swing-Handle Latch (-SH-): Tool-free front access during installs and MAC work; upgrade to SEAL Combo or SEAL Electronic on alternate SKUs if the space requires auditable or keyed access control.
- No-Fan Base Config (-00- Airflow): Ships passive — correct for light patch-panel-only loads. If you're dropping a 24-port PoE switch or a small UPS inside, budget for the fan variant upfront; retrofitting after wall-mounting is a nuisance.
Deployment Considerations:
- The 32" interior depth clears most 1U enterprise access switches without forced cable-bend compromises — confirm your deepest unit before ordering if you're running anything beyond standard 1U hardware.
- Wall structure is the limiting factor on 25U loaded installs: stud-to-stud anchoring or a plywood backer rated for the populated weight is non-negotiable. Do not rely on drywall anchors alone for a cabinet this size.
Best fit for school IDF closets, retail back-office network nodes, and warehouse edge switching points where floor space is genuinely at a premium and the equipment list is well-defined before the cabinet goes on the wall.
