Vertiv GL24WMCMS-B-SE-00-00 Wall Mount Network Enclosure
Overview
The Vertiv GL24WMCMS-B-SE-00-00 is a wall-mount enclosure built for IT closets, remote IDF locations, and network equipment staging areas where floor space is at a premium. This unit ships in a Black finish and is configured with a Swing Handle, SEAL Combo, and SEAL Electronic access control options — giving installers flexibility to match the physical security requirement of the deployment site. Offered across multiple depth and height configurations (24", 36", and 48" — corresponding to 12U, 19U, and 25U capacities), the GL24WMCMS-B-SE-00-00 (often searched as GL24WMCMS B SE 00 00) is sized to handle edge switching, patch panels, and small server gear without requiring a full floor-standing rack.
Key Features
- SEAL Electronic Access Control: Electronic locking means access events can be logged and credentials managed centrally — critical for compliance environments where auditors need a record of who opened the enclosure and when. This is a step above a keyed swing handle in any multi-technician or multi-tenant deployment.
- Swing Handle + SEAL Combo Options: The access control lineup spans from a basic swing handle through SEAL Combo to SEAL Electronic, so you can specify the right security tier per site — a distribution closet in a secured data center may only need the combo, while a remote IDF in an open office corridor benefits from electronic control.
- Fan Airflow Option: Active fan airflow keeps dense edge deployments cool without relying on convection — particularly important when you're packing a 12U or 19U wall cabinet with PoE switches and patch panels that run warm. Without active cooling, thermal throttling on switches in enclosed cabinets is a real-world failure mode in warm server rooms.
- Three Height Options — 12U, 19U, 25U: Deploying a 24" (12U) unit handles a pair of 1U switches and a patch panel cleanly. Stepping to 36" (19U) or 48" (25U) accommodates a small UPS, additional switching, or a 1U NVR if the wall-mount location doubles as a physical security edge node — no need to specify a different product family, just a different height.
- Door Options — Plexi, Mesh, Solid: Plexi doors let you visually confirm link lights and equipment status without opening the enclosure — useful in managed facilities. Mesh maximizes passive airflow if the fan option isn't selected. Solid provides the most physical security for public-facing locations.
- Cable Bar and Clear Cable Management Options: The Cable Bar option provides a dedicated horizontal raceway inside the cabinet so patch cords and power cables stay dressed and don't obstruct airflow or block equipment access. The Clear option keeps the interior visible while still routing cables, which matters in environments where technicians need quick visual triage without opening a door panel.
- Black or Winter White Finish: The Black finish (as configured on GL24WMCMS-B-SE-00-00) suits most server room and IDF closet deployments. Winter White is available for open-office or retail environments where the enclosure is visible and blending with the wall matters aesthetically.
Integration and Compatibility
The GL24WMCMS-B-SE-00-00 accepts standard 19-inch rack equipment — 1U, 2U, and 4U devices mount directly to the fixed vertical rail positions. The SEAL Electronic lock integrates with Vertiv's access control ecosystem, and the enclosure is designed to work within Vertiv's broader physical infrastructure lineup including their power distribution and thermal management accessories. For teams deploying network switches or network video recorders at edge locations, the multiple door and airflow configurations mean this cabinet can be specified to match both the thermal and security requirements of the site without custom fabrication. Refer to the wall mount enclosure category for alternative height and depth configurations across the Vertiv GL series, and review the rack and enclosure selection guide for help matching U-count to your equipment list before ordering.
Frequently Asked Questions
Q: What U-count does the GL24WMCMS-B-SE-00-00 provide?
A: The 24" height configuration provides 12U of rack space. The same product family also ships in 36" (19U) and 48" (25U) configurations — confirm the height option before ordering to ensure you have adequate space for your equipment list.
Q: Does the GL24WMCMS-B-SE-00-00 include active cooling?
A: Active fan airflow is an available option on this enclosure. If your deployment includes heat-generating switches or PoE injectors, specifying the fan configuration is recommended — passive convection in a sealed wall-mount cabinet often isn't sufficient for densely loaded equipment.
Q: What access control options are available on the GL24WMCMS-B-SE-00-00?
A: Three options are available: Swing Handle (basic mechanical), SEAL Combo (combination lock), and SEAL Electronic (electronic locking with credential management capability). The GL24WMCMS-B-SE-00-00 model designation includes the SE suffix, indicating SEAL Electronic access control configuration.
Q: Can I choose the door type on this enclosure?
A: Yes — Plexi, Mesh, and Solid door options are available. Plexi allows visual status checks without opening the door, Mesh supports maximum passive airflow, and Solid provides the highest physical security in public-access locations.
Q: What cable management configurations are offered?
A: Three options exist: None, Cable Bar, and Clear. The Cable Bar provides a physical horizontal raceway to dress patch and power cables. Clear cable management keeps the interior visible while still routing cables in an organized path.
Q: What color finish does the GL24WMCMS-B-SE-00-00 ship in?
A: The GL24WMCMS-B-SE-00-00 ships in Black. A Winter White finish variant is available in the same product family for installations where the enclosure will be visible in office or retail environments.
The GL24WMCMS-B-SE-00-00 is the configuration I'd specify when a deployment site needs electronic access logging on the enclosure itself — not just on the door to the IDF room. The SEAL Electronic locking mechanism means you can track credential use at the cabinet level, which matters in environments with multiple technicians, managed service providers sharing a space, or any compliance framework that requires equipment-level access records.
Technical Highlights:
- Three Height Options (12U / 19U / 25U): Specifying 12U (24") covers a typical edge node — a 1U switch, a patch panel, and a small PoE injector. Stepping to 19U or 25U accommodates a UPS or a 1U NVR without switching product families, which simplifies procurement and spare parts.
- Fan Airflow Configuration: Active fans are load-bearing in dense 12U installations where multiple PoE switches run continuously. I've seen thermal shutdowns in sealed wall cabinets without active cooling — it's not a spec to skip if you're filling more than 6U with active equipment.
- SEAL Electronic Access Control: Unlike a keyed or combo lock, the SEAL Electronic option supports credential-based access — directly relevant in multi-tenant facilities or anywhere a NIST 800-53 physical access log is expected. This isn't marketing differentiation; it changes the audit trail available to the facilities team.
Deployment Considerations:
- Confirm wall load rating before installation — a fully populated 25U wall cabinet with a UPS and switches can exceed 200 lbs; structural blocking between studs is typically required and should be specified in the site prep scope.
- The "None" cable management option saves cost but creates a maintenance headache in 19U+ deployments — if technicians will be adding or swapping equipment regularly, the Cable Bar option pays for itself in reduced re-cabling time.
This enclosure is well-matched to a distributed enterprise campus model — specifically IT closets on secure floors where physical access needs to be individually credentialed and auditable, and where floor-standing racks aren't an option due to space constraints.
