Vertiv GL48WMCMM-W-SC-00-CM 25U Wall-Mount Network Enclosure
Overview
The Vertiv GL48WMCMM-W-SC-00-CM is a 48-inch (25U) wall-mount enclosure finished in Winter White, configured with a SEAL Combo access control lock and cable management — a practical choice for small equipment rooms, IDF closets, and remote network deployment points where floor space is not available and a clean, lockable cabinet is required. This unit is part of Vertiv's Vertiv wall-mount enclosure line, a family that covers 12U, 19U, and 25U heights in both Black and Winter White finishes to match facility aesthetics or blend into clinical and light-colored environments.
The GL48WMCMM-W-SC-00-CM (often searched as GL48WMCMM W SC 00 CM) ships in the Winter White color variant, which is a deliberate specification choice for deployments in hospitals, clean rooms, education facilities, and retail environments where a black rack would stand out against light-colored walls. If your installation environment is a standard server room or data center, the black variant offers the same structural and functional specifications.
Key Features
- 25U (48-inch) Usable Depth: At the largest size in the GL48 family — which also comes in 24-inch/12U and 36-inch/19U configurations — the 25U variant gives you enough rack space to mount a small switch stack, patch panels, a UPS, and a wireless controller without stacking units outside the cabinet. That matters in IDF closets where every inch of wall is occupied.
- Winter White Finish: Not just a cosmetic option — Winter White is specified by facilities managers in healthcare, education, and retail environments where equipment must integrate with architectural standards. The GL48WMCMM-W-SC-00-CM satisfies that requirement without a custom paint job or enclosure wrap.
- SEAL Combo Access Control: The SEAL Combo lock provides physical security without the management overhead of electronic key systems. No batteries to fail, no credential provisioning — a combination that suits remote or unmanned telecom rooms where a simple auditable lock is preferred over electronic access.
- Cable Management Included: The CM suffix in the part number confirms cable management is included with this configuration. Structured cable management in a wall-mount cabinet reduces airflow restriction from bundled runs and keeps the interior serviceable when you need to swap a switch or re-terminate a patch panel — a real operational advantage over bare-rail cabinets.
- Door Options Available Across Family: The GL48 family supports Plexi, Mesh, and Solid door variants, giving you the option to specify by application — Plexi for visual status checks without opening the cabinet, Mesh for passive airflow in warmer spaces, Solid for physical security in public-access areas. Confirm the door type on this specific SKU before ordering if your application is door-dependent.
- Fan and Airflow Options: The family supports None or Fan airflow configurations. Wall-mount enclosures in tight spaces can trap heat from PoE switches and dense patch work — verify whether the active fan option is specified on this unit if thermal management is a concern for your load.
- Swing Handle Operation: The GL48 family also supports Swing Handle access control as an alternative to SEAL Combo or SEAL Electronic. The Combo variant on this SKU simplifies access management compared to electronic options while still providing a tamper-resistant enclosure for non-public installations.
Integration & Compatibility
The GL48WMCMM-W-SC-00-CM is designed as a general-purpose wall-mount network enclosure compatible with standard 19-inch rack equipment. The 25U height accommodates most commercial network switches, patch panels, and small UPS units. Cable management provisions support structured horizontal and vertical runs consistent with TIA-569 pathway practices. For installations requiring active cooling, verify the fan configuration at order time — the family supports both passive and fan-assisted airflow depending on thermal load. Integration with network infrastructure deployments is straightforward: standard 19-inch rail mounting, front-access swing door, and cable entry provisions for conduit or surface raceway connections. If your project requires electronic access logging at the cabinet level, evaluate the SEAL Electronic variant rather than this SEAL Combo unit.
Frequently Asked Questions
Q: What is the usable rack unit capacity of the GL48WMCMM-W-SC-00-CM?
A: The GL48WMCMM-W-SC-00-CM provides 25U of usable rack space in a 48-inch tall enclosure. The GL48 family also includes 12U (24-inch) and 19U (36-inch) configurations if your deployment requires a smaller footprint.
Q: What type of lock does the GL48WMCMM-W-SC-00-CM use?
A: This unit is configured with a SEAL Combo access control lock — a combination lock mechanism that provides physical security without requiring electronic credentials, batteries, or access management software. The GL48 family also offers Swing Handle and SEAL Electronic variants.
Q: Does the GL48WMCMM-W-SC-00-CM include cable management?
A: Yes. The CM suffix in the part number indicates cable management is included. The GL48 family supports None, Cable Bar, and Clear cable management configurations — this SKU includes cable management as a configured option.
Q: Why is the Winter White color specified on this model?
A: Winter White is specified for environments where aesthetic integration with light-colored walls is required — common in healthcare, education, and retail facilities. The GL48WMCMM-W-SC-00-CM is the Winter White variant; a Black finish is available in a separate SKU within the same family.
Q: Does this enclosure include a fan for active cooling?
A: The GL48 family supports both passive (None) and active (Fan) airflow configurations. Confirm the airflow specification on this specific SKU at order time if thermal management is critical for your equipment load.
Q: What door type does the GL48WMCMM-W-SC-00-CM ship with?
A: The GL48 family offers Plexi, Mesh, and Solid door options. Verify the door configuration for this specific part number at order time, as door type affects both airflow and physical security suitability for your deployment environment.
The GL48WMCMM-W-SC-00-CM covers the specific combination of 25U capacity, Winter White finish, SEAL Combo locking, and integrated cable management — a configuration I see most often in healthcare and education IDF deployments where the facilities team has color standards and the IT team needs a real 25U of usable space, not a compromise 12U or 19U that fills up after the first switch and patch panel go in.
Technical Highlights:
- 25U / 48-inch height: The largest configuration in the GL48 family gives you genuine flexibility — a 24-port PoE switch, two patch panels, a small UPS, and a wireless controller all fit without overflow mounting outside the cabinet.
- SEAL Combo lock: No battery replacement cycles, no credential provisioning headaches — this matters in remote IDF rooms that get visited twice a year for physical audits rather than daily by IT staff.
- CM (Cable Management) configuration: Structured cable management is the difference between a cabinet you can service in 10 minutes and one that requires an hour of untangling. The CM suffix confirms it ships configured — not as an afterthought add-on.
Deployment Considerations:
- The Winter White finish is a facility-driven spec, not a performance one — confirm your wall-mount anchoring matches the weight of a fully populated 25U cabinet before install; wall-mount enclosures at this height carry significant point loads on drywall or CMU.
- The GL48 family supports active fan airflow as an option, but this SKU's airflow configuration should be confirmed at order time — a fully loaded 25U wall-mount with a PoE switch stack in a closed room without active cooling can breach thermal limits for sensitive equipment.
This unit is the right specification for a multi-building education campus IDF refresh or a hospital wing network closet where aesthetics are a facilities requirement and 25U of properly managed rack space is the minimum to accommodate the equipment list without compromise.
