Vertiv GL36WMCMS-B-SE-00-00 19U Wall Mount Cabinet with Fan and Electronic Lock
Overview
The Vertiv GL36WMCMS-B-SE-00-00 is a 36-inch-deep, 19U wall mount enclosure designed for network equipment, patch panels, and edge computing deployments where floor space is not available. Available in Black or Winter White, this cabinet ships with active fan-assisted airflow, a SEAL electronic access control lock, and a choice of plexi, mesh, or solid door — giving you the configuration flexibility to match the thermal and security profile of the room it lives in. GL36WMCMS-B-SE-00-00 (often searched as GL36WMCMS B SE 00 00) is part of the broader Vertiv rack and enclosure line and is a practical fit for wiring closets, server rooms, and distributed IT deployments.
Key Features
- Three height options (12U / 19U / 25U): The 24-inch (12U), 36-inch (19U), and 48-inch (25U) variants let you right-size the enclosure to the number of rack units you actually need — avoiding the common mistake of over-ordering a half-empty floor cabinet for a four-switch stack. This listing covers the 19U configuration.
- Active fan airflow: Built-in fan cooling moves heat out of the enclosure rather than relying on passive convection. In a sealed wiring closet or low-ceiling IT room, this directly reduces the risk of thermal shutdown on active switches and routers — no supplemental cooling unit needed for moderate loads.
- SEAL Electronic access control: The electronic lock option steps up from a swing-handle or combination lock to credential-controlled entry — relevant anywhere you need an audit trail of who opened the cabinet and when. Paired with a mesh or plexi door, physical security and visibility coexist without cutting airflow to zero.
- Door style choices — Plexi, Mesh, or Solid: Plexi lets you visually confirm indicator lights without opening the cabinet (useful in unmanned wiring closets). Mesh maximizes passive airflow on the door face. Solid provides the highest physical security profile. Match the door to the environment, not a default.
- Cable management options — None, Cable Bar, or Clear: The cable management tier you select at order time determines how you route patch cables and power cords inside the enclosure. Cable bar provides horizontal cable routing. Clear panels keep the interior visible while protecting cabling. Skipping cable management entirely makes sense only in very low-density deployments.
- Black and Winter White color options: Wall mount cabinets in office environments often need to blend with the room. Winter White suits open office or lobby deployments; Black fits data closets and back-of-house installs. Both are available on the GL36WMCMS-B-SE-00-00 platform.
Integration and Compatibility
The 19-inch rack standard means any standard 1U–4U network switch, patch panel, or small server fits without adapter rails. The wall mount form factor is suited to network switch deployments, structured cabling termination points, and edge nodes in distributed environments. Pair with a UPS sized for the load inside the cabinet to protect against power events. For cable planning guidance, see the structured cabling selection guide. When deploying multiple cabinets across a campus or branch network, the rack and enclosure category carries companion floor-mount and open-frame options from the same Vertiv family.
Frequently Asked Questions
Q: What rack unit capacity does the GL36WMCMS-B-SE-00-00 provide?
A: This listing is the 19U (36-inch height) configuration. The same platform is also available in 12U (24-inch) and 25U (48-inch) variants.
Q: Does the GL36WMCMS-B-SE-00-00 include active cooling or is it passive only?
A: This configuration includes fan-assisted airflow. The platform also offers a no-fan (passive) variant — the fan option is indicated in the model number suffix.
Q: What type of lock does the GL36WMCMS-B-SE-00-00 ship with?
A: This model includes a SEAL Electronic lock. The platform supports Swing Handle and SEAL Combo locks as alternate configurations depending on the SKU ordered.
Q: Can I choose the door style when ordering the GL36WMCMS-B-SE-00-00?
A: Door style (Plexi, Mesh, or Solid) is a platform-level configuration option. Confirm the door type encoded in the specific SKU you are ordering — each variant has a distinct model suffix.
Q: What cable management is included with the GL36WMCMS-B-SE-00-00?
A: Cable management is configurable: None, Cable Bar, or Clear panel. Verify the cable management suffix in the ordered SKU to confirm what ships in the box.
The GL36WMCMS-B-SE-00-00 is the configuration I recommend when a customer needs credential-controlled access to a wall-hung enclosure — the SEAL Electronic lock is the differentiator here over a basic swing handle, and it matters when the cabinet sits in a shared space like a telecom room that multiple trades access during a build-out or renovation.
Technical Highlights:
- Fan-assisted airflow: Active cooling handles the thermal load of a populated 19U switch stack in a sealed closet — passive convection alone routinely causes thermal throttling on 24-port PoE switches running near capacity.
- SEAL Electronic lock: Credential-based entry provides an audit trail that swing-handle cabinets cannot. In environments subject to physical security audits or insurance requirements, this is a meaningful upgrade over a keyed lock.
- Configurable door styles (Plexi / Mesh / Solid): Plexi is the right call for unmanned closets where you need visual status checks without opening the cabinet; mesh maximizes airflow; solid maximizes physical deterrence. This platform lets you match the door to the actual threat model of the space.
Deployment Considerations:
- Wall load capacity and stud layout must be verified before installation — a fully populated 19U cabinet with patch panels and switches can exceed 150 lbs; confirm your wall blocking or strut channel supports the load before mounting.
- The cable management option (None / Cable Bar / Clear) is set at order time and is not field-swappable after the fact — specify the correct suffix upfront, especially for high-density patch deployments where horizontal cable management is non-negotiable.
This cabinet is the right fit for branch office IDF closets and retail back-of-house IT rooms where floor space is constrained, physical access control is required, and the equipment load justifies active thermal management.
