Vertiv GL790ES-3048-B-MS 42U 30" x 48" Black Mesh Server Rack Cabinet

Overview

The Vertiv GL790ES-3048-B-MS is a 42U rack enclosure built for data center rows and server rooms where structured cable management, reliable airflow, and long-term equipment density matter. At 30 inches wide and 48 inches deep, this cabinet accommodates full-depth server platforms and high-density switching gear without the footprint compromise of a shallower enclosure — 48" depth is the standard for 1U/2U rack servers with rear cable egress. The GL790ES-3048-B-MS (often searched as GL790ES 3048 B MS) is the black variant of Vertiv's ES cabinet line, a workhorse series deployed across enterprise data centers, colocation facilities, and large-scale network closets.

Key Features

• 42U Usable Height: 42U of rack space handles a dense mix of 1U servers, patch panels, and power distribution — enough vertical capacity for a fully loaded compute stack without stacking multiple cabinets in a constrained row.
• 30" Width: The 30-inch footprint is the standard data center rack width, compatible with most raised-floor tile grids and hot-aisle/cold-aisle containment systems — no custom flooring cutouts or aisle reconfiguration needed.
• 48" Depth: A 48-inch interior depth clears full-depth 1U/2U servers plus rear cable management arms without forcing cable bends — critical when running structured cabling to high-port-count top-of-rack switches.
• Mesh Contour Front Door: The mesh front door maintains airflow to front-breathing equipment while keeping dust ingress controlled. If you're running hot-aisle containment, mesh doors cooperate with containment curtains better than solid doors, which can create back-pressure.
• Mesh Contour Rear Door (or Split Mesh Rear): Rear mesh or split-mesh options let you select based on cable density — split rear panels simplify rear access in tight row configurations where swinging a full rear panel is impractical.
• Black Finish: The black powder-coat finish is standard for modern data center aesthetics and blends with the majority of rack-mount equipment bezels — relevant if your facility uses standardized row color-coding.

Integration & Compatibility

The GL790ES-3048-B-MS is built to EIA-310 rack standards, making it compatible with any standard 19-inch rack-mount equipment. The 30" x 48" footprint is compatible with typical raised-floor tile spacing. For network infrastructure deployments, this cabinet pairs with top-of-rack switching, UPS and power distribution units, and cable management accessories from the Vertiv rack and power lineup. Integrators planning high-density PoE switch installations should verify rear cable management arm clearance against the specific switch model's depth before ordering.

Frequently Asked Questions

Q: What are the exact dimensions of the GL790ES-3048-B-MS?

A: The GL790ES-3048-B-MS is a 42U rack cabinet with a 30-inch width and 48-inch depth. External dimensions will exceed these nominal values — consult the Vertiv ES series dimensional drawings for precise external height and footprint before planning raised-floor cutouts.

Q: What door configurations are available on this cabinet?

A: The GL790ES-3048-B-MS ships with mesh contour doors. The ES series offers Mesh Contour Front/Rear, Mesh Contour Front with Split Mesh Rear, and Clear door variants — confirm the door config from the specific MPN suffix when ordering.

Q: Is the GL790ES-3048-B-MS compatible with standard 19-inch rack equipment?

A: Yes. The ES series is built to EIA-310 standards, so any standard 19-inch rack-mount equipment — servers, switches, patch panels, PDUs — installs without adapter rails in most cases. Verify rail compatibility for older or non-standard chassis.

Q: Can this cabinet be used in a hot-aisle/cold-aisle containment setup?

A: The mesh contour doors on the GL790ES-3048-B-MS are compatible with hot-aisle/cold-aisle containment configurations. Mesh doors allow airflow through the containment boundary without back-pressure issues common with solid doors.

Q: What color options are available in the ES series?

A: The ES series is available in Black and Winter White. The GL790ES-3048-B-MS is the Black variant. Winter White variants carry a different MPN suffix.
