Vertiv GL910ES-3048-B-MS 48U 30" x 48" Black Mesh Rack Enclosure
Overview
The Vertiv GL910ES-3048-B-MS is a 48U rack enclosure in the Vertiv ES cabinet series, configured at 30 inches wide and 48 inches deep in a black finish. The 30-inch width accommodates standard 19-inch rackmount equipment with adequate side clearance for cable dressing, while the 48-inch depth handles today's deeper server and network gear without forcing awkward cable bends at the rear. If you're speccing a mid-to-large deployment where U count and airflow discipline both matter, this footprint covers most edge data center and wiring closet builds. The GL910ES-3048-B-MS (often searched as GL910ES 3048 B MS) is part of Vertiv's Vertiv rack and enclosure lineup, which spans multiple height, width, and depth configurations to suit different room layouts and equipment mixes.
Key Features
- 48U Capacity: 48 rack units gives you enough vertical space to house a full switching stack, patch panels, servers, and power distribution in a single enclosure — reducing the number of cabinets needed and the inter-cabinet cabling that comes with sprawl.
- 30" Width: Wider than the 19-inch EIA standard minimum, the 30-inch frame provides usable side channels for vertical cable managers without eating into the 19-inch equipment rail space — a practical advantage in dense network equipment builds where cable management is an afterthought until it becomes a crisis.
- 48" Depth: A 48-inch interior depth accommodates current-generation 1U and 2U servers, deep UPS units, and high-density patch fields without leaving cable slack piled at the back — and gives you room for rear PDU mounting without crowding airflow paths.
- Black Finish: The black powder-coat finish suits both open data center floors and enclosed server rooms where aesthetic consistency across cabinet rows matters to facilities teams.
- Mesh Contour Front/Rear Doors: Mesh door panels allow direct front-to-rear airflow without requiring you to leave doors open — a meaningful operational detail when the room's CRAC units are tuned to sealed-cabinet airflow assumptions. The contour profile also reduces the door's footprint when open in tight rows.
- Multiple Height and Width Variants Available: The ES series supports 24U, 42U, 44U, 48U, and 52U heights, and 24", 30", and 32" widths — so if this footprint doesn't match your floorplan, a sibling configuration likely does without switching enclosure families.
Integration and Compatibility
The GL910ES-3048-B-MS follows standard EIA-310 19-inch rail spacing, making it compatible with virtually all rackmount IT and network switch equipment. The ES series is designed to work alongside Vertiv power distribution units, cable management accessories, and blanking panels — consult the Vertiv ES series accessory catalog for rail kits, side panels, and PDU mounting options specific to this enclosure. For facilities planning your power and UPS infrastructure, confirm PDU form factor compatibility with the 48-inch depth before ordering.
Frequently Asked Questions
Q: What does the model number GL910ES-3048-B-MS tell me about this enclosure's configuration?
A: The GL910ES-3048-B-MS model number encodes the key configuration: 30-inch width, 48-inch depth, black finish (B), and mesh/split door configuration (MS). This makes it straightforward to identify the exact physical footprint and door type without cross-referencing a separate configuration chart.
Q: What door configurations are available in the ES cabinet series?
A: The ES series offers Mesh Contour Front/Rear, Mesh Contour Front with Split Mesh Rear, and Clear door options. The -MS suffix on this SKU indicates the mesh door configuration, which supports passive front-to-rear airflow.
Q: What other height and width options are available if 48U/30" doesn't fit my layout?
A: The Vertiv ES series supports 24U, 42U, 44U, 48U, and 52U heights, and 24-inch, 30-inch, and 32-inch widths, in both black and winter white finishes. Choose the sibling SKU matching your required footprint.
Q: Is the GL910ES-3048-B-MS compatible with standard 19-inch rackmount equipment?
A: Yes. The ES cabinet series uses standard EIA-310 19-inch rail spacing, so it accepts all standard 1U, 2U, and deeper rackmount equipment regardless of manufacturer.
Q: Does the mesh door on this enclosure affect cooling performance compared to solid doors?
A: Mesh doors allow direct front-to-rear airflow without requiring doors to be left open. This supports hot-aisle/cold-aisle configurations and is preferred when room cooling is designed around sealed-cabinet airflow. Solid or clear doors would restrict passive airflow and may require additional active cooling consideration.
The GL910ES-3048-B-MS sits at a practical crossroads for mid-density deployments: 48U of vertical space in a 30x48-inch footprint with mesh contour doors. The 48-inch depth is the spec I'd prioritize evaluating first — it's what separates enclosures that actually fit current-generation gear from ones that leave you fighting cable clearance on day one.
Technical Highlights:
- 48U Height: Provides enough vertical real estate for a complete edge stack — switching, patching, compute, and power distribution — in a single cabinet, which keeps inter-cabinet patching minimal.
- 30" Width: The extra width beyond a 24-inch frame opens up practical side-channel space for vertical cable managers, which matters in dense deployments where cable discipline directly affects serviceability.
- Mesh Contour Doors: Front and rear mesh panels maintain airflow compliance without requiring open-door operation, which matters for facilities teams running sealed-row cooling architectures.
Deployment Considerations:
- Confirm your floor tile cutout or raised-floor opening can accommodate the 30x48-inch base footprint before scheduling delivery — 48-inch-deep cabinets in tight rows require careful aisle clearance planning, especially when paired with rear door-mounted PDUs.
- Evidence for this SKU does not include load rating, rail type, or included accessory details — verify the specific weight capacity and rail kit compatibility with Vertiv's ES series documentation before speccing for high-density server loads.
This enclosure is a solid fit for enterprise wiring closets and small edge data center buildouts where the 48U count and 48-inch depth accommodate a full equipment stack without needing multiple cabinets — but confirm Vertiv PDU and cable management compatibility for your specific rail configuration before ordering.
