Vertiv GL790ES-2448-W-MSS 42U Server Rack Cabinet — Winter White, Split Mesh Rear Door
Overview
The Vertiv GL790ES-2448-W-MSS is a 42U rack enclosure built for data center rows, network equipment rooms, and surveillance head-end closets where physical footprint discipline and airflow management both matter. At 24 inches wide and 48 inches deep, it accommodates full-depth servers, high-density patch panels, NVR appliances, and UPS units without requiring a wide-aisle footprint — the 24-inch width keeps row density high in constrained machine rooms. The Winter White finish is a practical call for environments where light-colored infrastructure aids visual inspection and cable tracing without additional lighting.
The GL790ES-2448-W-MSS ships with a split mesh rear door — a detail that matters more than it sounds. Split doors allow independent access to upper and lower rear zones without swinging a full-height panel into the aisle, which is valuable in tight back-to-back row configurations. The mesh perforation supports passive convection and works with hot-aisle/cold-aisle containment strategies by not blocking exhaust airflow from rear-mounted equipment fans.
Key Features
- 42U Usable Height: 42U of rack space handles a fully populated surveillance head-end — multiple NVRs, patch panels, PoE switches, and a UPS — with room to grow. Planning at 70–80% fill leaves capacity for future expansion without a cabinet swap.
- 24-Inch Width: Narrower than the standard 600mm (23.6-inch) or 800mm (31.5-inch) footprints common in larger data centers, the 24-inch form factor fits corridor-side closets and branch office server rooms where floor space is constrained. Verify your floor tile or raised-floor grid spacing before committing to placement.
- 48-Inch Depth: The 48-inch depth accommodates full-depth 1U and 2U rack servers, high-density UPS units, and rear cable management arms without forcing equipment to hang off the rear rails. Most enterprise NVR appliances and PoE switches fit comfortably with room for structured cabling behind.
- Split Mesh Rear Door: Independent upper and lower rear access lets technicians service rear-mounted equipment — patch cables, power strips, cable arms — without fully obstructing the hot aisle. The mesh panels maintain continuous airflow even when both halves are closed, supporting standard thermal management practices.
- Mesh Contour Front Door Option: The front mesh contour door (GL790ES family standard) does not obstruct intake airflow to equipment with front-facing fans — a meaningful detail for dense PoE switch stacks and server nodes that rely on front-to-rear airflow.
- Winter White Finish: The Winter White color option (versus black) improves visual contrast inside the cabinet for cable identification and equipment status LED reading in machine rooms with moderate ambient lighting. It also matches common raised-floor data center aesthetics where white or light-gray infrastructure is the standard.
- Multi-Height Family (42U–52U Available): The GL790ES platform spans 24U through 52U heights — the GL790ES-2448-W-MSS sits in the most common enterprise deployment range. If your equipment manifest grows beyond 42U, the same family covers 44U, 48U, and 52U variants without switching rack ecosystems or accessory kits.
Integration and Compatibility
The GL790ES-2448-W-MSS is designed around standard 19-inch EIA-310 rail spacing, which means it accepts rack-mountable equipment from any vendor following that standard — NVRs, PoE switches, patch panels, KVM drawers, and PDUs all mount without modification. The 24-inch width is compatible with most 1U–4U rack servers and appliances that do not require side clearance beyond the rail ears.
When deploying surveillance head-ends, pair this cabinet with a PoE network switch and a rackmount UPS sized to your camera and NVR load — the 48-inch depth handles full-size 2U or 3U UPS units without rear overhang. For environments running network video recorders, the 42U height typically accommodates two to four NVR appliances alongside the supporting network infrastructure in a single cabinet. Review the Vertiv rack and infrastructure catalog for compatible PDUs, cable management panels, and blanking panels designed for this cabinet family. If you are planning a multi-cabinet row for a larger rack enclosure deployment, Vertiv offers bolt-together seismic brace kits and side panels for this series — confirm accessory compatibility against the GL790ES family spec sheet before ordering.
Frequently Asked Questions
Q: What rack unit height is the GL790ES-2448-W-MSS?
A: The GL790ES-2448-W-MSS is a 42U rack enclosure. The GL790ES platform also comes in 24U, 44U, 48U, and 52U heights if your equipment load requires a different size.
Q: What are the exact external dimensions of the GL790ES-2448-W-MSS?
A: The specified dimensions are 24 inches wide and 48 inches deep. Height corresponds to the 42U frame. Consult the Vertiv GL790ES datasheet for precise external millimeter dimensions and floor footprint measurements before finalizing placement.
Q: What door configuration does the GL790ES-2448-W-MSS ship with?
A: It ships with a mesh contour front door and a split mesh rear door. The split rear allows independent upper and lower access without swinging a full-height panel into the aisle — useful in tight back-to-back row layouts.
Q: Is the GL790ES-2448-W-MSS compatible with standard 19-inch rack equipment?
A: Yes. Like all GL790ES family cabinets, it uses standard EIA-310 19-inch rail spacing, so it accepts any rack-mountable equipment built to that standard — servers, NVRs, switches, patch panels, KVM drawers, and PDUs.
Q: Why choose Winter White over the black finish?
A: Winter White improves visual contrast inside the cabinet, making it easier to read equipment status LEDs and trace cables under standard machine room lighting. It also matches common raised-floor data center color schemes. If the installation is in a mixed-equipment room where aesthetics are secondary, the black variant offers identical mechanical specs.
Q: Can the GL790ES-2448-W-MSS be used in a surveillance head-end or security operations center?
A: Yes. The 42U height and 48-inch depth easily accommodate multiple NVR appliances, PoE switches, patch panels, and a rackmount UPS in a single cabinet — a common head-end configuration for mid-to-large surveillance deployments. The mesh doors support the front-to-rear airflow that NVR and server hardware requires for sustained operation.
When I spec a surveillance head-end rack, the rear door configuration is the first thing I check — and the GL790ES-2448-W-MSS's split mesh rear is the right call for any installation where you're servicing live equipment without taking a full aisle out of commission. That 48-inch depth means I'm not fighting rear cable management arms or having NVR units hang off the back rails, which is a real problem in 36-inch cabinets spec'd by someone who didn't measure the actual hardware.
Technical Highlights:
- Split Mesh Rear Door: Independent upper/lower access means a technician can pull a patch cable or reseat a power connection in the lower bay without disturbing active equipment in the upper half — a workflow advantage in any production head-end where downtime has a cost.
- 48-Inch Depth: Fits full-depth 2U NVR appliances, rackmount UPS units up to 3U, and structured cable management arms simultaneously — no compromise between equipment depth and rear cable routing.
- Winter White Finish: In machine rooms with standard fluorescent or LED strip lighting, white cabinet interiors meaningfully reduce the time spent squinting at port labels and status LEDs during installs and audits.
Deployment Considerations:
- Verify floor tile cutout dimensions and raised-floor grid spacing before delivery — the 24-inch width is narrower than the 600mm standard some raised-floor grids assume, and misaligned cutouts require adapters.
- The GL790ES-2448-W-MSS evidence does not include a rated static or dynamic load figure — confirm the Vertiv datasheet load capacity against your heaviest planned NVR or UPS unit before populating the cabinet fully.
This cabinet is the right fit for a mid-size physical security operations center or a branch-office surveillance head-end where a single 42U enclosure handles the complete NVR, switching, and power infrastructure — and where technicians need rear access without clearing an entire aisle.
