Vertiv GL300E-2432-B-SQM6MS 13U 24x32 Black Mesh Open-Frame Server Rack
Overview
The Vertiv GL300E-2432-B-SQM6MS is a 13U open-frame rack enclosure configured at 24 inches wide and 32 inches deep in black, with mesh front and rear doors. This configuration sits at the compact end of the GL300E family — a practical choice for edge deployments, IDF closets, branch office server rooms, and distributed surveillance head-end installations where space is constrained but you still need a properly-enclosed, mounting-rail-ready enclosure rather than a wall-panel or open-frame 2-post.
The GL300E series is available in multiple height, width, and depth combinations, so the GL300E-2432-B-SQM6MS (often searched as GL300E 2432 B SQM6MS) represents one specific build: 13U, 24-inch width, 32-inch depth, black finish, mesh front and rear door treatment, with M6 square-hole mounting rails. Understanding each dimension helps confirm fit before you order — detailed below.
Key Features
- 13U Usable Height: 13U provides enough space for a compact NVR or server, a PoE switch, a patch panel, and a UPS module — the typical surveillance head-end stack for a single-building deployment. If your equipment list exceeds 12–13U, you will need to step up to the 24U, 31U, 37U, or 44U variants available in the GL300E family.
- 24-Inch Interior Width: Standard 19-inch EIA rack equipment fits directly — the 24-inch cabinet width accommodates the rail sets with clearance. Note that this is the narrower width option in the GL300E line; a 29-inch-wide variant exists for equipment with wider cable management ears or side-exit cabling requirements.
- 32-Inch Depth: At 32 inches front-to-rear, this enclosure handles most 1U/2U servers, NVRs, and managed switches without rear-door interference. Deeper 2U UPS units or high-density patch panels should be measured against this depth before ordering; the GL300E line also offers a 36-inch depth option if you need the clearance.
- Mesh Front and Rear Doors: Mesh panels on both front and rear promote passive airflow through the enclosure — relevant in spaces without supplemental in-row cooling. Hot air exhausts through the rear mesh rather than recirculating inside the cabinet. If your site requires a physical security barrier on the door (tamper resistance) rather than just thermal management, the Plexi front / solid PV rear door option in the same model family may be more appropriate.
- M6 Square-Hole Mounting Rails (#10-32 / 3/8-inch sq.): M6 square-hole is the current standard for server and network equipment — most modern rack-mount gear ships with M6 cage nuts and screws. The rail specification here supports both #10-32 threaded and 3/8-inch square configurations, which covers the full range of rack-mount equipment you're likely to install. Confirm your equipment's rail requirements before ordering cage nut kits separately.
- Black Finish: The black colorway (versus the Winter White option available in the GL300E family) blends into server rooms, data closets, and low-light edge locations. If your deployment is in a retail, hospitality, or clinical environment where aesthetic visibility matters, the Winter White variant exists in the same family.
- Multi-Configuration Family: The GL300E-2432-B-SQM6MS is one node in a broader matrix of heights (13U, 24U, 31U, 37U, 44U), widths (24-inch, 29-inch), and depths (32-inch, 36-inch). This matters operationally: if your site has multiple locations with different equipment densities, you can standardize on the GL300E line and vary only the height/depth SKU rather than introducing a second enclosure brand.
Integration and Compatibility
The GL300E-2432-B-SQM6MS is compatible with standard 19-inch EIA-310 rack-mount equipment. The M6 square-hole rail pattern is universally accepted by server, NVR, managed switch, patch panel, and UPS vendors. For network video recorders and associated PoE switching infrastructure, this 13U form factor is a common fit in distributed surveillance deployments — particularly branch offices or retail locations where the full equipment stack is compact and the enclosure needs to live in a utility closet rather than a dedicated server room.
When pairing with Vertiv power and cooling products, confirm that the UPS footprint and depth fall within the 32-inch depth constraint. Vertiv's own rack PDUs and smaller UPS models are typically designed to the GL300E depth envelope, but always cross-reference physical dimensions. For broader rack enclosure selection guidance including height planning and rail compatibility, consult your equipment rack-unit count and depth spec sheet before committing to this configuration.
If you are deploying a PoE switch alongside NVR and server equipment in this enclosure, the mesh door treatment provides the passive airflow needed to keep switching equipment within operating temperature in a non-air-conditioned closet — a common real-world constraint in edge and branch deployments.
Frequently Asked Questions
Q: What is the usable rack height of the GL300E-2432-B-SQM6MS?
A: The GL300E-2432-B-SQM6MS provides 13U of usable rack space. The GL300E family also offers 24U, 31U, 37U, and 44U configurations if you need additional capacity.
Q: What mounting rail standard does the GL300E-2432-B-SQM6MS use?
A: The enclosure uses M6 square-hole mounting rails, compatible with standard #10-32 and 3/8-inch square hardware. This is the current EIA standard accepted by virtually all rack-mount servers, switches, NVRs, and UPS equipment.
Q: Why choose the 32-inch depth over the 36-inch depth option in the GL300E family?
A: The 32-inch depth is sufficient for most 1U and 2U servers, managed switches, and NVRs. Choose the 36-inch depth variant if you are installing deeper chassis, high-density patch panels with rear connector protrusions, or large-format UPS units that require additional rear clearance.
Q: Do the mesh doors on the GL300E-2432-B-SQM6MS support passive cooling?
A: Yes. Mesh front and rear doors promote natural front-to-rear airflow without requiring supplemental cooling in most light-load configurations. If physical door security (tamper resistance) is a priority over airflow, the GL300E family also offers a Plexi front / solid PV rear door configuration.
Q: Can I get the GL300E-2432-B-SQM6MS in a color other than black?
A: The GL300E series is available in a Winter White finish as an alternative to the black finish on this SKU. The Winter White option suits clinical, retail, or other environments where a darker enclosure would be visually prominent.
Q: Is the 24-inch width the only option, or is a wider cabinet available?
A: The GL300E family also offers a 29-inch width variant. The 29-inch option provides additional side clearance for equipment with wide cable management wings or side-exit cabling configurations that would be constrained in the 24-inch enclosure.
The GL300E-2432-B-SQM6MS is the configuration I reach for when a branch or edge location needs a properly-enclosed, ventilated rack but the floor plan won't give you a full 42U footprint. Thirteen usable rack units at 24 inches wide and 32 inches deep is genuinely compact — smaller than most office printer footprints — and the mesh front/rear door treatment means you're not fighting heat buildup in a utility closet with no CRAC unit.
Technical Highlights:
- 13U / 24x32 Form Factor: The 13U x 24-inch x 32-inch envelope fits a compact NVR, a single managed PoE switch, a small UPS, and a patch panel with room to spare — which is exactly the equipment stack for a 20–30 camera branch surveillance deployment in a retail or light industrial location.
- Mesh Front and Rear Doors: Passive front-to-rear airflow is not a luxury in a utility closet — it's often the only cooling available. The mesh treatment on both doors handles the thermal load of 1U/2U active equipment without supplemental cooling, provided ambient room temperature is within normal range.
- M6 Square-Hole Rails: Standard M6 square-hole mounting means no adapter kits and no compatibility surprises with modern server, NVR, or switch equipment. The #10-32 / 3/8-inch sq. support covers legacy hardware too, so a mixed-vintage equipment list isn't a problem.
Deployment Considerations:
- Confirm your deepest piece of equipment (typically the UPS or a 2U server) measures under 32 inches including rear connector protrusions before ordering. The 36-inch depth variant in the GL300E family exists for a reason — deep chassis hit the rear door on a 32-inch enclosure.
- The 13U height is the floor of the GL300E family. If your equipment list is already at 11–12U before you account for patch panels or horizontal cable managers, step up to 24U now — retrofitting a taller cabinet after install is a full teardown.
This enclosure earns its place in distributed surveillance and IT edge deployments — specifically the branch office or retail IDF where you need a standards-compliant, ventilated enclosure in a tight footprint and don't want to spec an oversized 42U just because it's familiar.
