Vertiv GL36WMCMS-W-SH-00-00 19U Wall Mount Cabinet Enclosure
Overview
The Vertiv GL36WMCMS-W-SH-00-00 is a configurable wall mount cabinet designed for structured cabling, network edge deployments, and telecom closets where floor space is limited but equipment density still matters. Available in 12U (24"), 19U (36"), and 25U (48") height configurations, this enclosure gives installers meaningful flexibility to match rack space to the actual equipment load — you're not forced into a fixed-height box. The Winter White color variant fits environments where aesthetics are part of the installation brief: office lobbies, healthcare corridors, and retail back-of-house runs where a dark industrial enclosure stands out the wrong way. If you're searching for this unit, it is also indexed as GL36WMCMS W SH 00 00 without hyphens.
Key Features
- Three Depth/Height Configurations (12U / 19U / 25U): Choosing the right rack unit count upfront prevents the all-too-common situation of purchasing a 12U enclosure for a 14U build. The 19U (36") and 25U (48") options give you genuine headroom for patch panels, switches, and UPS in a single wall-mounted footprint — no secondary enclosure needed for a typical IDF closet build.
- Winter White Finish: The Winter White color option isn't cosmetic-only. In environments with inspection requirements or where tenants have aesthetic approval rights — hospitals, corporate offices, educational facilities — a white enclosure blends into drop-ceiling and drywall environments rather than drawing attention. Ordering the correct color at commissioning avoids costly field repaints or enclosure swaps.
- Door Options — Plexi, Mesh, or Solid: Plexi doors let technicians visually confirm indicator lights and port activity without opening the enclosure — useful in unsupervised MDFs or wiring closets with limited access. Mesh doors maximize passive airflow for heat-generating active equipment. Solid doors suit environments where dust ingress or physical concealment is the priority. Match the door type to your actual thermal and access control requirements, not just habit.
- Access Control — Swing Handle, SEAL Combo, or SEAL Electronic: The swing handle is sufficient for secured IT rooms with existing door-level access control. The SEAL Combo adds individual enclosure-level accountability without cabling — a practical upgrade for multi-tenant or shared-space deployments where not everyone in the room should access every rack. The SEAL Electronic variant supports audit trail requirements: if your compliance framework requires a log of who opened the enclosure and when, this is the lock tier to specify.
- Airflow — None or Fan: Passive (no fan) configurations are appropriate for low-density patch panel and copper termination builds where heat output is minimal. The fan option becomes necessary once you introduce active switching or PoE midspans that sustain load continuously. Specifying fan airflow at order time is cleaner than retrofitting — the fan option integrates into the enclosure's thermal management design rather than adding an external unit.
- Cable Management — None, Cable Bar, or Clear: The cable bar option organizes horizontal runs and prevents cable sag that stresses RJ-45 terminations over time — a real maintenance cost driver in high-port-count patch environments. The clear cable management option provides full organization visibility, which matters during moves/adds/changes when a technician needs to trace a specific run without pulling every cable. Specifying cable management at order time ensures factory-fitted mounting points rather than field-drilled workarounds.
Integration and Compatibility
The GL36WMCMS-W-SH-00-00 follows the 19" EIA standard rack form factor, meaning standard 1U and 2U patch panels, switches, and accessories mount without adapter plates. The configurable access control options — particularly the SEAL Electronic variant — integrate into broader physical security frameworks where enclosure-level access logging is part of the audit trail. For deployments pairing this enclosure with active PoE switching, the fan airflow option should be specified to handle sustained thermal output from loaded PoE ports. Browse the full Vertiv enclosure and power catalog for compatible accessories and complementary infrastructure. For wall mount cabinet selection guidance, the wall mount enclosures category covers the full available range. If you're planning a structured cabling build, structured cabling infrastructure covers patch panels, cable management, and termination hardware that pairs directly with this enclosure. For PoE-loaded active equipment going into the rack, cross-reference your PoE network switches thermal output against the enclosure's fan option capacity before finalizing the configuration.
Frequently Asked Questions
Q: What rack unit sizes are available for the GL36WMCMS-W-SH-00-00?
A: The GL36WMCMS-W-SH-00-00 is available in three height configurations: 24" (12U), 36" (19U), and 48" (25U). Select the configuration that matches your equipment count with room for cable management and future adds.
Q: What door types can I specify on this enclosure?
A: Three door options are available: Plexi (polycarbonate clear front for visual indicator monitoring), Mesh (maximizes passive airflow), and Solid (dust protection and physical concealment). The door type is specified at order time.
Q: What access control options are available on the GL36WMCMS-W-SH-00-00?
A: Three lock tiers are available: Swing Handle (standard key lock), SEAL Combo (combination lock, no cabling required), and SEAL Electronic (electronic lock with audit trail capability for compliance-sensitive environments).
Q: Does this enclosure support active cooling?
A: Yes — the GL36WMCMS-W-SH-00-00 offers a Fan airflow option for deployments with active switching or PoE equipment that generates sustained heat load. Passive (no fan) is appropriate for low-density or patch-only builds.
Q: Is cable management included, or is it a separate add-on?
A: Cable management is a configurable option at order time: None, Cable Bar, or Clear. Specifying cable management upfront ensures factory-fitted mounting rather than field modifications after delivery.
Q: What colors does the GL36WMCMS-W-SH-00-00 come in?
A: The enclosure is available in Black and Winter White. The Winter White variant (this listing) suits office, healthcare, and retail environments where a black industrial cabinet would be aesthetically inappropriate.
The GL36WMCMS-W-SH-00-00 is one of those enclosures that rewards careful configuration at the order stage — the modular option set (three heights, three door types, three lock tiers, two airflow modes, three cable management levels) means you can dial it precisely to the deployment rather than compromising. The SEAL Electronic access control option is the spec I'd flag first for any multi-tenant or compliance-driven environment: enclosure-level access logging is a low-cost way to close an audit gap that a room-level badge reader alone doesn't cover.
Technical Highlights:
- 19U (36") Height Option: The mid-size configuration handles a full IDF build — 24-port patch panel, 1U managed switch, PoE midspan, and a 1U UPS — without oversizing to a floor-standing cabinet. Right-sizing the enclosure to the actual load keeps wall loading predictable and simplifies structural mounting calculations.
- SEAL Electronic Lock: Electronic access control at the enclosure level supports per-technician credential assignment. In environments running SOC 2 or PCI-DSS audits, this is the difference between a clean physical access log and a finding.
- Fan Airflow Option: A loaded 24-port PoE+ switch sustaining 370W of port output in a sealed enclosure will thermal-throttle within an hour in a warm closet. The factory fan option addresses this at the design stage — don't spec passive airflow for active PoE deployments and retrofit later.
Deployment Considerations:
- For the 25U (48") configuration, verify wall stud spacing and load rating before mounting — a fully populated 25U enclosure with patch panels and active gear can exceed typical drywall anchor ratings. Concrete or steel-stud anchoring is the right call for the larger heights.
- The Plexi door option, while convenient for visual checks, does not provide the same dust ingress resistance as a solid door — in dusty or high-particulate environments (warehouses, light manufacturing), specify solid and plan for periodic internal cleaning instead.
This enclosure is the right specification for a healthcare facility IDF where aesthetics, access accountability, and thermal management all matter simultaneously — the Winter White finish, SEAL Electronic lock, and fan option together cover requirements that a standard black swing-handle cabinet simply doesn't address in a single SKU.
