Vertiv GL790ES-2448-B-MSS 42U Server Rack Enclosure with Split Mesh Rear Door
Overview
The Vertiv GL790ES-2448-B-MSS is a 42U server rack enclosure built for structured IT and security infrastructure deployments where footprint control and rear access flexibility matter. At 24 inches wide and 48 inches deep, this cabinet fits standard rack equipment while providing enough depth for high-density server, storage, and network gear without forcing a larger floor footprint. The black finish suits both production data rooms and security head-end closets where aesthetics are a secondary concern to cable discipline and serviceability.
The GL790ES-2448-B-MSS (often searched as GL790ES 2448 B MSS) ships in the Vertiv Geist ES Cab lineup — a series designed around clean airflow management and field-serviceable door configurations. The split mesh rear door is the defining feature of this SKU: two independently opening half-width panels give technicians direct access to the rear of any rack unit without swinging a full-width door into an adjacent cabinet or aisle obstruction. In tight rows where rear clearance is measured in inches, that distinction matters operationally.
Key Features
- 42U usable height: accommodates a full stack of 1U–4U equipment — servers, patch panels, PDUs, KVM switches — without needing a second cabinet for a typical head-end build-out.
- 24" width: the narrower 24-inch profile fits wall-mount alcoves, network closets, and side-by-side row configurations where a 30- or 32-inch cabinet would not. Verify your rack unit widths are standard 19-inch EIA-310 before ordering.
- 48" depth: provides clearance for full-depth servers and rear-cabled PDUs simultaneously — 48 inches is the practical minimum for 1U/2U rack servers with cable management arms.
- Split mesh rear door (MSS): two independent rear panels open left or right independently, critical in zero-clearance aisle configurations where a single full-width door cannot be opened without moving adjacent equipment.
- Mesh contour front door: perforated mesh promotes passive front-to-rear airflow, reducing the heat load on any in-cabinet cooling and maintaining positive pressure alignment with hot-aisle/cold-aisle containment schemes.
- Black finish: standard for production environments; blends with network infrastructure and security head-end gear without requiring custom finishes.
Integration and Compatibility
The GL790ES-2448-B-MSS is designed for standard 19-inch EIA-310 rack-mount equipment. The 48-inch depth is compatible with full-depth 1U–4U servers, NVR appliances, and network switches commonly deployed in video surveillance head-end rooms. The ES Cab series supports Vertiv's accessory ecosystem including PDU mounting, blanking panels, and cable management rails — verify accessory compatibility against the GL790ES series documentation before ordering non-standard configurations.
