Vertiv GL980ES-3048-B-MSS 52U 30"x48" Black Server Rack Cabinet with Split Mesh Rear Door
Overview
The Vertiv GL980ES-3048-B-MSS is a commercial-grade open-frame rack enclosure from Vertiv's Vertiv server rack and enclosure line, configured at 30 inches wide and 48 inches deep with a black finish and split mesh rear door. The GL980ES series is designed for data center, server room, and IT closet deployments where airflow management, structured cabling access, and long-term structural integrity matter. This specific SKU — GL980ES-3048-B-MSS (also searched as GL980ES 3048 B MSS) — targets environments that require rear-access flexibility without compromising front-to-back airflow paths.
As a server rack enclosure, the GL980 fits structured deployments where integrators need a reliable physical layer foundation for compute, storage, and networking gear. The 30-inch width accommodates standard 19-inch EIA rack equipment while leaving room for vertical cable managers and side-mounted PDUs without cramping the interior. The 48-inch depth handles most 2U and 4U servers, deep UPS units, and rear-mounted patch panels with cable slack loops — a common pain point in shallower 42-inch enclosures.
Key Features
- 30" Width: Wider than the minimum 24" footprint, the 30-inch profile gives integrators usable side space for vertical cable managers and airflow baffles without requiring a full 32-inch wide footprint — useful in tight raised-floor rows.
- 48" Depth: Accommodates deep blade chassis, extended 4U servers, and rear-mounted UPS modules. If your deepest equipment runs past 36 inches with cable slack, a 48-inch enclosure eliminates the door-clearance headaches a 42-inch unit creates.
- Split Mesh Rear Door (MSS): The split rear configuration lets you open one half of the rear door independently — critical when the enclosure is in a tight row and full rear-door swing would block an adjacent cabinet or wall. Mesh panels preserve natural convection and active cooling airflow paths without blocking exhaust.
- Mesh Contour Front Door: Front mesh promotes cold-aisle intake directly to equipment intake fans, reducing hot-spot risk in high-density rows. Available in mesh contour front/rear or mesh contour front/split mesh rear configurations.
- Black Finish: Standard black powder coat. If your deployment requires a lighter color profile for visual contrast in inventory environments, the GL980 line also offers Winter White — the GL980ES-3048-B-MSS is specifically the black variant.
- Multiple Height Options in the GL980ES Family: The GL980ES series spans 24U through 52U, giving you vertical scaling flexibility within the same footprint. Choose depth and width once; adjust U count to match rack density requirements per row.
Integration and Compatibility
The GL980ES-3048-B-MSS is a standard EIA 19-inch rack enclosure compatible with all standard rack-mount equipment. It integrates with Vertiv's broader PDU and power distribution ecosystem and is designed to accept Vertiv's own accessory line including blanking panels, cable managers, and mounting hardware. For structured cabling environments, the 48-inch depth pairs cleanly with rear-mounted patch panels and horizontal cable managers at the top and bottom of the cabinet. Confirm exact accessory compatibility with Vertiv's GL980ES accessory matrix for this specific width/depth combination before ordering cable management hardware, as some side-mount kits are width-specific.
Frequently Asked Questions
Q: What door configuration comes with the GL980ES-3048-B-MSS?
A: The GL980ES-3048-B-MSS ships with a mesh contour front door and a split mesh rear door (the MSS suffix denotes the split rear). The split rear allows independent access to each half of the rear panel, which is useful in tight row deployments.
Q: Is the GL980ES-3048-B-MSS available in colors other than black?
A: The GL980ES series is available in Black and Winter White. The GL980ES-3048-B-MSS is specifically the black variant. For Winter White, you would need the corresponding -W-MSS SKU in the same family.
Q: What rack unit heights are available in the GL980ES family?
A: The GL980ES series is available in 24U, 42U, 44U, 48U, and 52U heights across various width and depth configurations. Confirm the specific U count for the GL980ES-3048-B-MSS variant directly with your distributor or Vertiv's product selector.
Q: What widths and depths are available in the GL980ES series?
A: The GL980ES series spans 24", 30", and 32" widths, and 42" or 48" depths. The GL980ES-3048-B-MSS is the 30" wide, 48" deep configuration.
Q: Is the GL980ES-3048-B-MSS compatible with standard 19-inch rack equipment?
A: Yes. Like all GL980ES enclosures, it uses standard EIA 19-inch rack mounting rails, making it compatible with any standard rack-mount servers, switches, patch panels, PDUs, and other 19-inch equipment.
The GL980ES-3048-B-MSS is the configuration I'd reach for when a deployment combines deep servers — think dual-socket 4U storage nodes or extended blade chassis — with a constrained row footprint that makes full rear-door swing impractical. The 48-inch depth and split mesh rear door on this unit solve two problems simultaneously: you get the clearance you need for deep equipment plus rear cable access without needing aisle clearance for a full-width door swing.
Technical Highlights:
- Split Mesh Rear Door: Independent left/right panel access is genuinely useful in dense rows — you open only the half you need, which matters when adjacent cabinets or containment curtains eat into swing clearance.
- 30" Width vs. 32": The 30-inch profile hits a practical sweet spot — wide enough for side cable management, narrow enough to fit standard 600mm floor tile grids without overhang adjustments.
- 48" Depth: Handles equipment that a 42-inch cabinet can't without forcing awkward cable bends at the rear door. If you're racking anything deeper than 30 inches with patch slack, this is the minimum depth to consider.
Deployment Considerations:
- The GL980ES series spans multiple heights (24U through 52U) — verify the exact U count for the GL980ES-3048-B-MSS SKU with your distributor before quoting the project, as the MPN's height encoding is not fully explicit from the available spec sheet.
- The black finish is standard for data center environments, but if the deployment is a visibility-sensitive operations center where technicians track equipment by color coding, the Winter White variant may be worth considering for contrast.
This enclosure is the right fit for enterprise server rooms and edge data center deployments where row density is high, equipment is deep, and rear access needs to stay practical after the cabinet is populated and cabled.
