Vertiv GL36WMCMS-B-SH-00-00 19U Wall Mount Network Cabinet with Fan
Overview
The Vertiv GL36WMCMS-B-SH-00-00 is a 19-inch, 36-inch-tall (19U) wall mount cabinet built for network closets, server rooms, and surveillance equipment rooms where floor space is at a premium. This specific configuration ships in gray with fan-assisted airflow, a swing handle access control mechanism, and factory-integrated cable management — a combination suited to installations that need active thermal control in a compact, lockable enclosure without the footprint of a full floor rack. Whether you're mounting a small NVR stack, patch panel, or edge switching gear, GL36WMCMS-B-SH-00-00 (often searched as GL36WMCMS B SH 00 00) delivers the structural rigidity and airflow management that commercial-grade deployments require.
The GL36WMCMS-B-SH-00-00 is part of Vertiv's Vertiv wall mount enclosure line, which spans 12U, 19U, and 25U heights with configurable door, color, airflow, and access options — so you can match enclosure depth and capacity to the actual rack density of your installation rather than over-buying a floor cabinet.
Key Features
- 19U (36-inch) Form Factor: The 19U interior gives you enough rack space for a mid-density edge deployment — think 1–2U switch, 1U patch panel, a compact NVR, and a PoE injector — without committing to the floor space of a 24U or 42U standing rack. Wall mounting keeps the gear off the ground and out of the way in tight comms closets or retail back-of-house installs. Browse the full range of wall mount network cabinets to compare U-counts across the family.
- Fan Airflow Configuration: Active fan airflow means this enclosure moves air through the rack rather than relying on passive convection. That matters when you're running a PoE switch and an NVR simultaneously — heat-generating equipment in a sealed wall enclosure with no forced airflow will thermal-throttle or fail prematurely. The fan option is the right call for any install with more than one or two power-drawing devices.
- Swing Handle Access Control: The swing handle mechanism provides quick single-handed access without requiring a key or electronic credential — appropriate for locked server rooms or controlled-access closets where physical security of the space is the primary perimeter, and where technicians need to get in quickly during maintenance. If the installation environment requires individual enclosure-level audit trails, step up to the SEAL Electronic access variant instead.
- Gray (Black Available) Color: The gray finish integrates cleanly into office and commercial environments — less industrial-looking than a matte black cabinet in a customer-visible space. Black is available in the same GL-series product family for data center and back-of-house environments where aesthetics are secondary.
- Multiple Door Options — Plexi, Mesh, or Solid: While this SKU ships with a specific door configuration, understanding the tradeoff matters for rack selection: a plexi door gives visual status-check access without opening the enclosure (LED visibility for switch/NVR health); mesh maximizes passive airflow; solid provides the cleanest appearance and light dust protection. Match the door to your monitoring workflow — if technicians need to eyeball port LEDs daily, plexi saves repeated open/close cycles. See Vertiv's network equipment cabinet catalog for door variants within the family.
- Cable Management Options — None, Cable Bar, or Clear: This configuration includes factory-integrated cable management, which keeps patch runs organized and prevents cable sag from blocking airflow paths through the fan-cooled interior. In a 19U wall cabinet where cable routing space is inherently tighter than a floor rack, built-in management is a meaningful labor and airflow advantage over retrofitting aftermarket cable managers later. For structured cabling planning, a structured cabling selection guide can help size cable management correctly for your patch density.
- Height Family — 12U/19U/25U Available: The GL-series spans three heights (24-inch/12U, 36-inch/19U, and 48-inch/25U). This SKU is the 19U mid-size. If your device count is 6U or fewer, the 12U variant avoids wasted rack space. If you're running a full NVR with camera license storage expansion plus switching and patch gear, evaluate the 25U before committing to the 19U — running out of rack units in a wall mount is harder to fix than in a floor cabinet. A rack unit planning guide can help right-size before you mount.
Integration & Compatibility
The GL36WMCMS-B-SH-00-00 accepts standard EIA 19-inch rack-mount equipment. It is compatible with 1U, 2U, and deeper rackmount devices — verify the internal depth against your deepest device (typically a UPS or NVR) before specifying. The fan airflow configuration is designed to pair with heat-generating network and AV equipment; coordinate fan exhaust direction with room ventilation to avoid recirculating warm exhaust back into the inlet. The swing handle access control is a purely mechanical mechanism with no wiring requirement, simplifying installation compared to electronic lock variants. Wall mounting hardware and structural requirements (stud spacing, wall type, load rating) should be verified against Vertiv's installation documentation for this model.
Frequently Asked Questions
Q: What is the rack unit capacity of the GL36WMCMS-B-SH-00-00?
A: The GL36WMCMS-B-SH-00-00 is a 19U enclosure (36-inch height). The GL-series also comes in 12U (24-inch) and 25U (48-inch) configurations if you need a different capacity.
Q: Does the GL36WMCMS-B-SH-00-00 come with active cooling or is it passive only?
A: This specific configuration includes fan airflow — it is not a passive-only enclosure. The fan option actively moves air through the cabinet, which is the correct choice when running heat-generating equipment like PoE switches, NVRs, or UPS units inside a sealed wall mount.
Q: What type of lock or access control does the GL36WMCMS-B-SH-00-00 use?
A: The GL36WMCMS-B-SH-00-00 uses a swing handle access mechanism. This is a mechanical handle — no wiring, no electronic credentials required. The GL-series also supports SEAL Combo and SEAL Electronic access options in other configurations if audit-trail or keypad access is needed.
Q: What door type does this enclosure ship with?
A: The GL-series is available with Plexi, Mesh, or Solid door options. Confirm the exact door type for your specific configuration from the product spec sheet. Plexi allows LED visibility without opening; mesh maximizes passive airflow; solid provides the cleanest appearance and dust resistance.
Q: Does the GL36WMCMS-B-SH-00-00 include cable management?
A: Yes. Cable management options in the GL-series include None, Cable Bar, and Clear. This configured SKU includes cable management — verify the exact type (Cable Bar or Clear) from the order documentation, as both are available in the product family.
Q: What color does the GL36WMCMS-B-SH-00-00 ship in?
A: This SKU ships in gray (listed as a Winter White/Gray variant in the Vertiv GL-series). Black is also available within the product family for different configurations.
The GL36WMCMS-B-SH-00-00 is the configuration I recommend when someone has a comms closet with real heat load — a PoE switch, compact NVR, and maybe a UPS — and they're tempted to just throw it in a passive wall enclosure to save a few dollars. The fan airflow option in this SKU is not optional in that scenario; passive convection in a sealed 19U wall cabinet with two or three heat-generating devices will shorten equipment life noticeably, and you won't notice until something starts dropping off the network at 2am.
Technical Highlights:
- Fan Airflow (Active Cooling): Unlike the passive variant of this enclosure, the fan configuration actively evacuates heat from the cabinet interior — critical when total rack power draw exceeds ~100W in a sealed wall mount environment. Most NVR + switch + patch panel combinations exceed that threshold.
- 19U / 36-inch Capacity: Nineteen rack units is the practical sweet spot for an edge surveillance or network closet that needs more than a 12U but doesn't justify a floor rack — room for a 1U switch, 1U patch panel, 2U NVR, and a 2U UPS with U's to spare for future expansion.
- Swing Handle Access Control: No wiring, no programming, no battery — the swing handle is purely mechanical. That simplicity means zero installation overhead beyond mounting the cabinet itself, and no credential management burden for the facilities team managing the space.
Deployment Considerations:
- Verify internal depth against your deepest device before ordering — wall mount cabinets have tighter depth tolerances than floor racks, and a deep UPS or NVR that doesn't seat fully will prevent the door from closing properly.
- The gray color finish is a legitimate differentiator in customer-facing or office-adjacent installs, but confirm the wall substrate and stud spacing can support the combined weight of the enclosure plus a fully loaded 19U rack — wall mount cabinets are frequently under-specified on the structural side.
This enclosure is a strong fit for distributed enterprise surveillance deployments where each building or floor has its own edge NVR and switching stack — the GL36WMCMS-B-SH-00-00 keeps that gear organized, cooled, and access-controlled without requiring a dedicated server room at every site.
