Vertiv GL910ES-3042-W-MS 48U White Mesh Server Rack Enclosure
Overview
The Vertiv GL910ES-3042-W-MS is a white, 30-inch-wide by 42-inch-deep rack enclosure from the Vertiv ES cabinet line — a commercial-grade steel enclosure sized for mid-density IT and network equipment deployments where rack aesthetics matter alongside airflow. The “W” in the part number confirms the Winter White finish, making this a practical fit for office-facing data closets, NOC environments, or clean-room deployments where black cabinets read as too industrial. The GL910ES-3042-W-MS (often searched as GL910ES 3042 W MS) ships in a configurable height range spanning 24U through 52U, with this listing covering the 48U build.
Key Features
- 30-inch width: The 30” footprint splits the difference between a compact 24” rack and a full 32” cabinet — useful when floor space is limited but you still need side-by-side cable management or dual PDU mounting without crowding the equipment rails.
- 42-inch depth: 42” of usable depth accommodates most 1U–2U servers, patch panels, and dense switch chassis without forcing cable management compromises at the rear. Shallower than a 48” option, which helps in tighter rooms.
- Winter White finish: Purpose-built for environments where equipment aesthetics are a functional requirement — broadcast studios, healthcare IT closets, retail back-offices. The white powder coat also makes heat-spot thermal scans easier to read visually compared to dark enclosures.
- Mesh Contour Front / Split Mesh Rear doors: Perforated mesh doors allow passive convective airflow without requiring blanking panels to seal every unused U — reducing the risk of hot-spot accumulation in lightly populated racks. The split rear door eases rear access in tight row configurations without swinging a full-width door into an adjacent aisle.
- Height flexibility (24U to 52U family): The GL910ES line scales from 24U to 52U, so if rack density requirements change, the same footprint and color family are available without sourcing a different product line.
Integration & Compatibility
The ES enclosure series is designed around standard 19-inch EIA-310 rail spacing, making it compatible with conventional rack-mount servers, switches, patch panels, KVM drawers, and PDUs from any major vendor. The 42-inch depth accommodates most full-depth enterprise chassis. Pair with a rack PDU and structured cable management accessories to complete a tidy deployment.

Frequently Asked Questions
Q: What does the “MS” suffix mean in GL910ES-3042-W-MS?
A: In Vertiv’s ES cabinet naming convention, “MS” indicates a mesh split rear door configuration — the rear door is split into two panels for easier access in tight row deployments.
Q: What rail spacing does the GL910ES-3042-W-MS use?
A: The ES cabinet series uses standard EIA-310 19-inch rail spacing, compatible with all conventional rack-mount IT equipment.
Q: Can the GL910ES-3042-W-MS be ordered in black instead of white?
A: The “W” in the part number designates Winter White. The ES line is available in black (“B” suffix) as a separate SKU — contact us for the black equivalent if required.
Q: Is the 42-inch depth sufficient for full-depth servers?
A: Yes. A 42-inch internal depth accommodates most full-depth 1U and 2U server platforms, including typical enterprise chassis in the 28–36-inch range, with clearance for rear cable management.
Q: What heights are available in the GL910ES-3042-W-MS product family?
A: The ES cabinet line spans 24U, 42U, 44U, 48U, and 52U configurations in the 30” × 42” footprint. Confirm the specific U-count with the part number or order confirmation.
The GL910ES-3042-W-MS is a specification I see requested most often in environments where the rack is customer-visible or sits in a space with non-standard aesthetic requirements. The 30” × 42” footprint in Winter White is a deliberate choice — not a default — and the split mesh rear door is what makes it workable in dense row configurations where a full swing door would block aisle access.
Technical Highlights:
- 30” Width: Narrow enough to fit secondary IT closets and telecom rooms that can’t accommodate a full 32” cabinet, but wide enough to mount dual vertical PDUs alongside equipment rails without interference.
- 42” Depth: Hits the practical sweet spot for mixed server/switch/patch deployments — deep enough for full-chassis gear, shallow enough to leave rear cable management room without eating into hot-aisle clearance.
- Mesh Contour / Split Mesh Doors: Passive airflow through perforated doors eliminates reliance on blanking panels in lightly loaded racks. The split rear configuration reduces the minimum aisle width needed for full rear access by roughly half.
Deployment Considerations:
- The Winter White finish is a powder coat, not a film — it holds up to typical data-center cleaning protocols, but verify touch-up paint availability from Vertiv before committing to a multi-rack white deployment where cosmetic consistency matters over time.
- Height selection (24U through 52U) is encoded in the full SKU string — the base GL910ES-3042-W-MS designation covers the family; confirm the exact U-count on your purchase order to avoid receiving the wrong height.
This enclosure is a strong fit for healthcare IT closets, broadcast infrastructure rooms, and retail back-office deployments where white equipment is a facility requirement and the 30” × 42” footprint matches a pre-planned floor grid.
