Vertiv GL840N12-3042-SS-AFA2-1032 45U NEMA Data Cabinet
Overview
The Vertiv GL840N12-3042-SS-AFA2-1032 is a 45U, 30-inch-wide by 42-inch-deep NEMA-rated steel data cabinet finished in black — a purpose-built enclosure for server, switch, and structured cabling deployments where equipment density and cable management depth both matter. At 45U, this cabinet handles a full rack of 1U/2U servers or a mixed compute-and-switching load without compromise. If you are outfitting a data center row, a wiring closet, or a server room expansion and need a cabinet that ships with a known footprint and a verified rack unit count, the GL840N12-3042-SS-AFA2-1032 is a straightforward fit.
Vertiv's geist and Liebert cabinet lines are a common anchor point in enterprise and mid-market IT rooms — browse the Vertiv infrastructure catalog to see companion power, cooling, and monitoring products that pair with this enclosure. For buyers evaluating cabinet sizing across multiple racks, the server racks and cabinets category page covers the full portfolio.
Key Features
- 45U Rack Space: 45 rack units gives you room for a full high-density server stack — typically 40+ 1U appliances or a mix of 2U/4U compute with patch panels on top and bottom. You won't need to split a deployment across two cabinets to fit a standard server count.
- 30-Inch Width: The 30in body width is the standard footprint for most enterprise data halls and wiring closets. Rows align cleanly without special spacing, and side panels close flush against adjacently mounted cabinets in a row configuration.
- 42-Inch Depth: A 42in interior depth accommodates full-depth servers — including dual-PSU 1U and 2U rack servers with rear cable routing — without forcing front-rail setbacks. This also leaves clearance for rear cable management brackets and airflow baffles.
- NEMA-Rated Enclosure: NEMA construction means the steel gauge and seam tolerances meet North American enclosure standards for data equipment — relevant for deployments in facilities managed under NEMA compliance requirements or where the enclosure must integrate with grounded bonding schemes.
- Black Finish: Standard black powder coat integrates with mixed-vendor rows in enterprise data halls and matches most OEM rack accessories without a color mismatch. Practical for visual organization using color-coded cable management in a dark-finish enclosure.
- Commercial-Grade Steel Construction: Built for static and dynamic load requirements typical in server room environments — compatible with infrastructure accessories including cable management arms, blanking panels, and PDU mounting configurations.
Integration and Compatibility
This cabinet accepts standard EIA-310 19-inch rack equipment on both front and rear rails, making it compatible with server, network, and storage hardware from all major vendors. The 42-inch depth is suited for pairing with rear-mount UPS and power management devices, vertical PDUs, and cable management arms without requiring custom rail kits. For structured cabling buildouts, patch panels and fiber distribution units mount directly to the front rails while active equipment occupies the middle and rear positions.
Buyers configuring a full rack should account for PDU placement, airflow direction (front-to-rear vs. hot-aisle containment), and floor tile cutout alignment when specifying the GL840N12-3042-SS-AFA2-1032 in a new row.

Frequently Asked Questions
Q: What is the rack unit capacity of the GL840N12-3042-SS-AFA2-1032?
A: The GL840N12-3042-SS-AFA2-1032 provides 45U of usable rack space, suitable for high-density server and switching deployments.
Q: What are the external footprint dimensions of this cabinet?
A: The cabinet is 30 inches wide and 42 inches deep. Verify total height with Vertiv documentation for floor planning and aisle clearance calculations.
Q: What equipment depth can this cabinet accommodate?
A: At 42 inches of internal depth, this cabinet fits full-depth rack servers and dual-PSU appliances while leaving room for rear cable management hardware.
Q: Is this cabinet compatible with standard 19-inch rack equipment?
A: Yes. The GL840N12-3042-SS-AFA2-1032 uses EIA-310-compliant 19-inch rails, compatible with server, switching, storage, and patching hardware from all major vendors.
Q: What is the NEMA rating for this cabinet?
A: The cabinet carries a NEMA enclosure designation per the product specification. Confirm the specific NEMA type (e.g., Type 1 or Type 12) with Vertiv documentation for your compliance requirements.
Q: Can this cabinet be used in a hot-aisle/cold-aisle containment configuration?
A: Yes. The 30x42in footprint and standard front-to-rear airflow path are compatible with hot-aisle containment systems. Confirm blanking panel density and PDU placement for proper airflow management in your row design.
The GL840N12-3042-SS-AFA2-1032 is the cabinet I reach for when a customer needs a known-quantity 45U enclosure with a 30x42in footprint and doesn't want to gamble on whether full-depth hardware will actually fit — the 42-inch interior depth is the spec that matters most here, and Vertiv delivers it in a NEMA-rated steel body that holds up in production data hall conditions.
Technical Highlights:
- 45U Capacity: Enough rack space to house a complete high-density compute stack — 40+ 1U servers or a mixed server-and-switching load — without splitting the deployment across two enclosures.
- 42-Inch Depth: Accommodates full-depth dual-PSU rack servers with room left over for rear cable management arms and vertical PDU mounting — no front-rail setbacks required.
- 30-Inch Standard Width: Aligns with EIA row spacing in enterprise data halls and matches the footprint of adjacent Vertiv and third-party cabinets for clean row build-outs.
Deployment Considerations:
- Before finalizing floor layout, verify the total installed height (cabinet body plus leveling feet or casters) against ceiling clearance and raised floor tile grid alignment — the 45U body height combined with base options can push the overall unit taller than a standard 7-foot ceiling allows.
- NEMA type is listed as 'NEMA' in the product specification without a sub-type designation — confirm Type 1 vs. Type 12 with Vertiv's documentation if your facility's compliance requirements distinguish between indoor-use and dust-resistant enclosures.
This cabinet is well-suited for enterprise server room row expansions and edge data center builds where a full 45U of EIA-310-compliant space, a confirmed 42-inch depth, and a standard 30-inch width need to land in one SKU without custom-order lead times.
