Vertiv GL790ES-3048-W-MS 42U 30x48 White Server Cabinet
Overview
The Vertiv GL790ES-3048-W-MS is a 42U, 30-inch-wide by 48-inch-deep enclosed server cabinet finished in Winter White — a practical choice for data centers, server rooms, or network closets where equipment aesthetics matter alongside airflow and access. The GL790ES-3048-W-MS ships with mesh contour front and rear doors, which means perforated airflow paths are built into the door design itself rather than relying on blanking panels alone. That matters on fully loaded racks where passive airflow restriction is the first cause of thermal events.
The Vertiv server cabinet line covers a wide range of form factors — this specific configuration targets mid-to-large deployments that need 42U of usable height, adequate footprint depth for full-length 1U servers and patch management, and a finish that reads as intentional in a client-facing or co-located environment rather than a utility closet.
Key Features
- 42U Height: Accommodates standard 1.75-inch rack units across 42 positions — enough vertical real estate for a full server stack, patch panels, KVM, PDUs, and cable management without stacking two cabinets. The GL790ES family also comes in 24U, 44U, 48U, and 52U if your rail count is higher or lower.
- 30-Inch Width: Standard 19-inch EIA rail spacing inside a 30-inch-wide enclosure leaves room for side cable routing without forcing equipment into a 32-inch footprint. If your raised floor tiles or hot-aisle containment system is sized for 30-inch racks, this fits without layout redesign.
- 48-Inch Depth: At 48 inches, the cabinet clears most 2-socket 1U and 2U servers including cable slack at both ends. The 42-inch depth variant exists in the GL790ES family — spec the 48-inch when your cable management or GPU-extended servers push past 36 inches of chassis plus connector overhang.
- Mesh Contour Front and Rear Doors: Perforated mesh doors on both front and rear let hot exhaust escape at the rear without recirculating back through the front intake. In a properly contained hot-aisle/cold-aisle row, this eliminates the need for blanking panels as an airflow shortcut — though you should still blank empty Us for proper pressure differentials.
- Winter White Finish: This is not a cosmetic-only decision. White enclosures are standard in medical, laboratory, broadcast, and certain financial trading floor environments where color-coding distinguishes rack types or where client-visible installations require a non-industrial appearance. If you are deploying in a standard IT data center, the black variant in the same family may be more appropriate.
- Multiple Door Configurations Available: The GL790ES series supports mesh contour front/rear, mesh contour front with split mesh rear, and clear door options — useful when you need front visibility for indicator lights or require single-door vs. split-door rear access based on row density.
Integration and Compatibility
The GL790ES-3048-W-MS is a standard server cabinet built to EIA-310 rail specifications. It accepts standard 19-inch rack-mount equipment from any manufacturer. When planning power distribution, pair with a rack-mount PDU sized for your total load — the 48-inch depth provides adequate vertical PDU mounting space at the rear uprights. For structured cabling, the 30-inch width allows 1U and 2U cable managers on the front uprights without conflicting with patch panel access. If you are building a hot-aisle containment row, confirm aisle containment hardware compatibility with the GL790ES door hinge clearance before ordering containment panels.
Frequently Asked Questions
Q: What is the usable rack height of the GL790ES-3048-W-MS?
A: The GL790ES-3048-W-MS provides 42U of usable rack space, accommodating standard 1.75-inch rack-unit equipment across 42 positions.
Q: Does the GL790ES-3048-W-MS come with mesh doors?
A: Yes. This model ships with mesh contour front and rear doors, which allow passive airflow through the cabinet without requiring additional perforation panels.
Q: Is the GL790ES-3048-W-MS available in black?
A: The GL790ES series is available in both Black and Winter White. This specific model (GL790ES-3048-W-MS) is the Winter White configuration. Consult the GL790ES family for the equivalent black model.
Q: What depth server will fit in the GL790ES-3048-W-MS?
A: The 48-inch internal depth accommodates most full-depth 1U and 2U servers, including extended-chassis GPU servers, with room for cable management slack at both ends. Measure your longest chassis plus connector and cable overhang against available internal depth before ordering.
Q: Can the GL790ES-3048-W-MS be used in a hot-aisle/cold-aisle containment setup?
A: Yes. The mesh contour front and rear doors are designed for passive airflow, making the cabinet compatible with hot-aisle/cold-aisle layouts. Verify containment hardware clearances against the cabinet's door hinge dimensions for your specific containment system.
The GL790ES-3048-W-MS is the configuration I recommend when a client needs a 42U footprint in a 30-inch-wide row and the deployment context calls for Winter White — whether that is a medical imaging suite, a broadcast facility rack room, or a financial trading floor where white racks denote a specific function in a color-coded layout. The 48-inch depth is the right call over the 42-inch variant any time you are mixing standard servers with GPU-extended chassis or dense cable management trays at the rear.
Technical Highlights:
- 42U Capacity: Enough vertical space to house a full converged stack — compute, storage, top-of-rack switching, and PDUs — without splitting across two cabinets and adding inter-cabinet cabling complexity.
- 30-Inch Width: Fits standard hot-aisle/cold-aisle row layouts designed for 30-inch cabinets without requiring floor tile reconfiguration or containment panel re-cutting.
- Mesh Contour Doors Front and Rear: Passive airflow paths are built into both door panels — this is the correct door choice for any deployment running more than a few kilowatts per rack, where solid doors would require active door cooling modules to compensate.
Deployment Considerations:
- The Winter White finish is a deliberate spec for specific environments — if your site is a standard IT data center with no color-coding requirement, the black GL790ES variant avoids the aesthetic mismatch of a white cabinet in a black-rack row.
- At 48 inches of depth, confirm your raised floor cutouts and cable tray drops are positioned to reach the rear of the cabinet without creating sharp bend-radius violations on fiber or DAC runs.
This cabinet is a strong fit for client-visible server rooms, medical or laboratory environments, and broadcast infrastructure racks where Winter White finish is a site specification — and where 42U of mesh-door capacity handles the thermal load without supplemental door cooling.
