Vertiv GL790ES-2448-B-MS 42U 600mm x 1200mm Black Open-Frame Server Rack Cabinet
Overview
The Vertiv GL790ES-2448-B-MS is a 42U, 24-inch-wide by 48-inch-deep enclosed rack cabinet finished in black — a purpose-built enclosure for data center rows, IDF closets, and security head-end rooms where airflow management and structural rigidity matter more than raw floor space. The GL790ES-2448-B-MS ships as part of Vertiv's ES series, a line that balances physical security with ventilation through mesh contour door configurations. If you're specifying a mid-depth, narrow-footprint rack for a constrained server room or a branch office comms closet, this is the configuration to evaluate first.

Key Features
- 42U Usable Height: 42U provides roughly 73.5 inches of mounting space — enough for a full complement of 1U/2U servers, patch panels, and power distribution units without stacking enclosures. If your deployment is a dense NVR stack plus PoE switches for a large network video recorder system, 42U gives you room to grow without a second cabinet.
- 24-Inch Width: The 24-inch form factor fits tighter spaces than the 30- or 32-inch variants in the ES family. Useful when aisle width is constrained or when the cabinet sits inside a closet alongside other infrastructure. Verify your equipment's rail width requirements — some higher-density servers and UPS units assume 19-inch EIA rails within a 30-inch wide enclosure.
- 48-Inch Depth: At 48 inches deep, this cabinet accommodates longer 2-post and 4-post equipment without the cable-management pain of a shallow rack. Full-depth servers, high-capacity NVRs, and rackmount UPS units all fit cleanly. If your load is primarily 1U switches and patch panels, the 42-inch depth variant in the same family keeps the footprint tighter.
- Mesh Contour Front and Rear Doors: The mesh contour door option delivers substantially better passive airflow than solid or perforated steel — critical when you're running 24/7 recording servers or dense PoE switch stacks that throw significant heat. The GL790ES-2448-B-MS also offers a split mesh rear door configuration, which allows rear cable access without fully opening the door — a practical detail during maintenance windows on live systems.
- Black Finish: Standard black finish integrates cleanly into most data center and server room environments. The ES series also ships in Winter White for environments where aesthetics or room-specific color coding matter — order that variant if your deployment specifies it.
- ES Series Scalability: The GL790ES line spans 24U through 52U heights and 24-inch through 32-inch widths, so you can standardize on the same enclosure family across rooms with different density requirements. Consistent rail systems and door hardware reduce spare-parts overhead.
Integration and Compatibility
The GL790ES-2448-B-MS is designed around standard 19-inch EIA-310 rail mounting, compatible with virtually all rackmount IT and security infrastructure — servers, NVRs, managed network switches, patch panels, and rackmount UPS units. The mesh contour door clearances support front-to-rear airflow for standard server and network equipment cooling architectures. For high-density thermal loads, pair with a rackmount UPS and in-row cooling to keep inlet temperatures within equipment specs. The split-rear-door option eases hot-aisle containment integration without requiring a full blanking-panel retrofit.
Frequently Asked Questions
Q: What is the usable rack unit height of the GL790ES-2448-B-MS?
A: The GL790ES-2448-B-MS provides 42U of usable mounting space.
Q: What door options are available on the GL790ES-2448-B-MS?
A: The GL790ES-2448-B-MS supports Mesh Contour Front/Rear, Mesh Contour Front with Split Mesh Rear, and Clear door configurations depending on the variant ordered.
Q: Does the GL790ES-2448-B-MS come in colors other than black?
A: Yes. The ES series ships in Black and Winter White. The GL790ES-2448-B-MS specifically is the black finish configuration.
Q: What equipment depth does this cabinet support?
A: The cabinet is 48 inches deep, accommodating full-depth servers, NVRs, and rackmount UPS units without extension hardware.
Q: What width rack equipment does the GL790ES-2448-B-MS accept?
A: The cabinet uses standard 19-inch EIA-310 rail mounting within its 24-inch-wide enclosure — compatible with standard 1U through 10U rackmount equipment.
The GL790ES-2448-B-MS is the configuration I'd specify for a branch office IDF or a security head-end room where you need a full 42U of usable space but the floor plan won't accommodate a 30-inch-wide cabinet. The 24-inch width is the defining constraint here — confirm your heaviest equipment's mounting depth against the 48-inch interior before finalizing the order.
Technical Highlights:
- 48-Inch Depth: Handles full-depth NVRs and servers without rear-cable compression — the common failure mode in 29-inch-deep cabinets when patching 24-port switches.
- Mesh Contour Doors: Passive airflow through the mesh contour front and rear outperforms perforated steel in high-CFM switch/server mixes; split rear door option means you can access rear cable management without opening the full door during a live maintenance window.
- 42U in a Narrow Footprint: 42U at 24 inches wide is a space-efficient ratio for security infrastructure racks — room for NVRs, PoE switches, a rackmount UPS, and patch panels in a single enclosure without a second cabinet footprint.
Deployment Considerations:
- The 24-inch width assumes all installed equipment fits within standard 19-inch EIA rails — verify that any proprietary chassis or wide-format UPS units don't require a 30-inch enclosure before specifying this model.
- Mesh contour doors provide excellent airflow but offer less physical security than solid locking doors — if the cabinet sits in an unsecured or semi-public space, evaluate whether the clear-door or a locking solid-door variant better fits your physical security policy.
This cabinet is the right call for a multi-camera surveillance head-end build — stack your NVRs in the bottom half, PoE switches mid-rack, and patch panel plus UPS at the top, and the 48-inch depth gives every component the cable-routing room it needs without a second enclosure.
