Vertiv GL36WMCMP-B-SH-00-CM 19U Wall Mount Network Enclosure
Overview
The GL36WMCMP-B-SH-00-CM is a 19U (36-inch) wall-mount enclosure from Vertiv's Geist WM Premium line, finished in black with a plexi door and SEAL electronic access control. It is sized for telecom closets, IDF rooms, and edge deployments where floor space is constrained but you still need a secure, ventilated home for active networking and network switching gear. The enclosure ships in a 36-inch height configuration (19U usable rack space), while the WM Premium family also covers 24-inch (12U) and 48-inch (25U) builds — so you can standardize on the same product line across sites with different rack density requirements. For broader context on the full line, see the Vertiv enclosure and infrastructure catalog.
Key Features
- 19U of usable rack space (36-inch height): Comfortably fits a small core stack — a managed PoE switch, a patch panel, and a UPS — without requiring a floor-standing cabinet. The 24U mount point envelope keeps wall-loading predictable on standard stud or concrete installations.
- Plexi door (this configuration): Clear plexi gives you visual LED status-checks on every piece of gear without unlocking the enclosure. Useful in IDF closets where staff need to confirm link lights are green without opening the door. The WM Premium line also offers mesh and solid door variants if airflow or physical opacity requirements differ at your site.
- SEAL Electronic access control: This SKU ships with SEAL Electronic locking — a credential-based lock mechanism that logs access events, replacing the standard swing-handle found on base configurations. In multi-tenant or compliance-sensitive environments (SOC 2, HIPAA IT closets), electronic locking eliminates the shared-key problem and supports audit trail requirements. The family also offers Swing Handle and SEAL Combo options for deployments where electronic credentialing isn't in scope.
- Fan airflow option: The GL36WMCMP-B-SH-00-CM includes active fan airflow — critical once you install a PoE switch delivering 200W+ to IP cameras or access control readers. Passive enclosures trap heat in confined closets; the integrated fan option moves air across the equipment shelf and out of the enclosure before thermal throttling becomes a risk. Pair this with a PoE switch sized to your camera count to keep the thermal budget honest.
- Cable bar cable management: The cable bar option on this build keeps patch runs organized and strain-relieved at the enclosure entry points — important when you are cabling to a network video recorder or access control panel and need to identify circuits without chasing unlabeled bundles.
- Black finish: The black color option blends into most commercial interior environments. The WM Premium line is also available in Winter White for environments where a dark enclosure would stand out (healthcare corridors, clean-room perimeters).
- Configurable across the family: Door, color, access control, airflow, and cable management are all selectable at order time within the WM Premium line — the GL36WMCMP-B-SH-00-CM (often searched as GL36WMCMP B SH 00 CM) reflects one specific factory configuration, so confirm the option string before ordering if your site requirements differ.
Integration and Compatibility
The 19-inch rail spacing accepts standard EIA-310 rackmount equipment. The wall-mount form factor fits alongside access control panels and edge compute nodes in locations where a two-post or four-post floor rack is impractical. Verify your wall structure's load rating against the total populated weight of the enclosure before installation — concrete block and steel stud installations have different anchoring requirements than wood-frame walls.
Frequently Asked Questions
Q: What door types are available in the Vertiv WM Premium line?
A: The WM Premium family is offered with Plexi, Mesh, and Solid door options. This specific configuration (GL36WMCMP-B-SH-00-CM) ships with a Plexi door.
Q: What access control options does this enclosure support?
A: The WM Premium line supports Swing Handle, SEAL Combo, and SEAL Electronic access control. This SKU is configured with SEAL Electronic locking.
Q: Does the GL36WMCMP-B-SH-00-CM include active cooling?
A: Yes. This configuration includes fan airflow. The WM Premium line also offers a no-fan (None) option for passive deployments with lower heat loads.
Q: What rack unit capacity does this enclosure provide?
A: The 36-inch height version provides 19U of usable rack space. The WM Premium family also includes 24-inch (12U) and 48-inch (25U) configurations.
Q: What color options are available?
A: Black and Winter White. This SKU ships in Black.
Q: What cable management is included in this configuration?
A: This build includes a Cable Bar. The family also supports a Clear option and no cable management (None) depending on configuration.
The GL36WMCMP-B-SH-00-CM is the configuration I reach for when a deployment has a compliance angle — specifically the SEAL Electronic lock, which gives you credential-based access logging on an IDF closet without installing a separate reader and controller. That is a meaningful simplification in SOC 2 or HIPAA environments where every access point needs an audit trail.
Technical Highlights:
- SEAL Electronic Access Control: Replaces shared-key swing handles with credential-based locking — eliminates the audit gap that open-key cabinets create in compliance-driven sites.
- Fan Airflow: Active cooling keeps a populated 19U stack (PoE switch, patch panel, edge compute) below thermal throttle thresholds in confined IDF closets where passive enclosures regularly overheat gear.
- Plexi Door: Allows LED status verification without opening the enclosure — reduces unnecessary access events in environments where every open-door event is logged against a credential.
Deployment Considerations:
- Confirm wall structure load capacity before mounting a fully populated 19U enclosure — concrete block and steel stud anchoring requirements differ significantly from wood-frame walls, and Vertiv's install guide should be the reference, not general contractor estimates.
- The option string in the part number is load-bearing: GL36WMCMP-B-SH-00-CM encodes Black finish, SEAL Electronic, fan, and cable bar — ordering a different suffix gets you a different configuration, so verify before placing the PO.
Best fit: multi-tenant commercial buildings or healthcare IT closets where the enclosure serves a small active stack (switch, patch, UPS) and electronic access logging is a compliance requirement rather than a preference.
