Vertiv GL790ES-2448-W-MS 42U Network Rack Enclosure — 24" x 48", Winter White

The Vertiv GL790ES-2448-W-MS is a 42U, 24-inch-wide by 48-inch-deep rack enclosure finished in Winter White — a practical choice when equipment rooms share office or lab space where a standard black cabinet would draw attention or conflict with facility aesthetics. Part of the Vertiv rack and enclosure line, the GL790ES series ships in multiple height and width configurations, making it straightforward to spec the right footprint without overbuilding. The GL790ES-2448-W-MS specifically fills the mid-density sweet spot: enough vertical space for a fully populated access-layer switch stack, a patch panel run, and a 2U UPS, without the floor-loading concerns of a 48U or 52U cabinet in a weight-sensitive raised floor environment.

Why the 24" x 48" Footprint Matters

Rack width and depth are often treated as afterthoughts until equipment doesn't fit or airflow suffers. At 24 inches wide, this cabinet matches standard EIA rack-unit mounting rails without wasted lateral space — relevant when you're tiling cabinets side-by-side in a network enclosure row and every inch of aisle clearance counts. The 48-inch depth accommodates most 1U/2U switches, patch panels, and mid-depth servers without forcing cable management arms into a compressed space. If your equipment runs shallower than 48 inches, the extra depth becomes usable rear cable management real estate rather than dead air.

Key Features

• 42U Mounting Height: 42U is the de facto standard for mid-density deployments — enough vertical space to fully populate a PoE switch stack, structured cabling panels, and a UPS in a single cabinet without the floor-load overhead of a taller frame. If you're running out of 1U slots before you run out of floor space, the 44U and 48U variants in the same GL790ES family can add margin without a footprint change.
• 24" Cabinet Width: Matches standard 19-inch EIA mounting rail spacing while keeping the external envelope compact. In tight IDF closets or lab rows where you're placing multiple cabinets side-by-side, the narrower external width preserves aisle clearance compared to 30- or 32-inch-wide alternatives in the same GL790ES series.
• 48" Depth: Comfortably handles mid-depth networking gear and patch panel builds. Shallower 42-inch-depth cabinets can force awkward cable routing on rear-exhaust switches — the extra 6 inches here gives you room to dress cables properly without compromising rear-door clearance.
• Mesh Contour Front and Rear Doors: Perforated mesh doors promote passive front-to-rear airflow without requiring the doors to be propped open or removed. If your cooling strategy relies on contained hot-aisle/cold-aisle architecture, closed mesh doors keep the thermal boundary intact while still passing adequate CFM for typical networking loads. This is the right door choice for enclosed equipment rooms; skip it only if you need a clear door for visual indicator monitoring without opening the cabinet.
• Winter White Finish: The GL790ES-2448-W-MS ships in Winter White rather than standard black — the practical difference is visibility in bright lab environments and aesthetic fit in white-finish data center rows or office-adjacent equipment rooms. White cabinets also make it easier to spot dust accumulation on mesh panels during routine inspection walks.
• Multi-Configuration Family: The GL790ES series spans 24U through 52U heights and 24-, 30-, and 32-inch widths, with both 42- and 48-inch depth options. Specifying from a single product family across a multi-cabinet deployment simplifies procurement, spare-parts stocking, and blanking panel inventory — all variants share common accessory compatibility (rails, PDU mounting, cable management).
• Door Configuration Options: Available with mesh contour front/rear, mesh contour front/split mesh rear, or clear doors depending on the variant selected. The split rear door option on other SKUs in the family is useful when you need half-door access for cable entry without swinging a full rear panel — worth confirming on the order if rear-access workflow matters for your install team.

Integration and Compatibility

The GL790ES-2448-W-MS follows standard 19-inch EIA-310 mounting rail spacing, so it accepts off-the-shelf rack-mount equipment from any vendor without adapter hardware. Standard vertical rail hole patterns support both square-hole and round-hole cage nuts depending on your rail configuration. For rack accessories — PDU mounting, 1U/2U cable managers, blanking panels, and shelf kits — the GL790ES series uses Vertiv's standard accessory ecosystem, which is broadly stocked through commercial infrastructure channels. Confirm rail depth compatibility when mounting deep 2-post-style equipment that requires mid-rail support, as 48-inch depth can occasionally require extended mounting hardware for certain UPS models.

The GL790ES-2448-W-MS (often searched as GL790ES 2448 W MS) is a straightforward specification when you need a white-finish, mid-density enclosure with reliable mesh-door airflow and standard 19-inch rail compatibility — no exotic accessories, no proprietary tooling.

Frequently Asked Questions

Q: What is the external footprint of the GL790ES-2448-W-MS?

A: The GL790ES-2448-W-MS has a 24-inch width and 48-inch depth. The 42U height corresponds to approximately 73.5 inches of usable rack space (42 × 1.75 inches per U). Verify exact external dimensions including door swing clearance against your room layout before ordering.

Q: What door style does the GL790ES-2448-W-MS ship with?

A: This SKU ships with a Mesh Contour front door and Mesh Contour rear door. The perforated mesh design supports passive front-to-rear airflow for networking and switching equipment without requiring doors to remain open.

Q: Can the GL790ES-2448-W-MS accommodate standard 19-inch rack equipment?

A: Yes. The GL790ES series uses standard 19-inch EIA-310 mounting rail spacing, compatible with virtually all rack-mount networking, switching, patching, and power equipment from any manufacturer.

Q: Why choose the Winter White finish over the standard black version?

A: Winter White is the right specification when the cabinet will be installed in a white-finish data center row, a lab environment, or an office-adjacent equipment room where visual consistency with facility finishes matters. White also makes dust accumulation on mesh panels easier to spot during maintenance walks.

Q: What other height options are available in the GL790ES series?

A: The GL790ES family spans 24U, 42U, 44U, 48U, and 52U heights across 24-, 30-, and 32-inch width options, with 42- and 48-inch depth variants. This makes it practical to standardize on one product family across a mixed-density deployment.

Q: Is the GL790ES-2448-W-MS suitable for hot-aisle/cold-aisle containment?

A: The mesh contour doors support front-to-rear airflow, which is compatible with hot-aisle/cold-aisle containment architecture. The closed mesh doors maintain the thermal boundary while passing adequate airflow for typical switching and patching loads.
