Vertiv GL42UEX-80120B-MS-SC 42U Server Rack Enclosure

Overview

The Vertiv GL42UEX-80120B-MS-SC is a 42U rack enclosure from the Vertiv EX series, built for enterprise data centers, network equipment rooms, and dense compute deployments where physical infrastructure needs to be as reliable as the equipment it houses. At 800mm wide and 1200mm deep, this enclosure accommodates full-depth servers, high-density patch panels, and cable management hardware without forcing compromises on airflow routing or rear-access clearance. If you are speccing a new build or a rack refresh and need a commercially deployable enclosure with real depth — not a shallow 600mm unit that strains cable bend radii — the GL42UEX-80120B-MS-SC is the configuration to evaluate.

Key Features

• 42U Height: 42U of usable rack space gives you room to fully populate a standard server bay — that is roughly 73.5 inches of equipment mounting height, enough to mix 1U/2U servers, a top-of-rack switch, patch panels, and a cable management arm without running out of units mid-build. No need to split workloads across two half-height racks.
• 800mm Width: The 800mm wide footprint — wider than the base 600mm EIA standard — accommodates wider server chassis, side-by-side cable management, and blanking panel setups that maintain proper airflow separation between hot and cold aisles. Many blade enclosures and dense switch chassis specify 800mm as their minimum rack width requirement.
• 1200mm Depth: 1200mm depth is a meaningful spec for full-depth infrastructure. Standard 1U and 2U rack servers run 700–900mm in chassis depth; adding rear cable management, PDU mounting, and airflow baffles on a 900mm or 1000mm rack creates real constraint. The 1200mm depth on this enclosure leaves margin for structured cabling and rear PDU mounting without compromising airflow or forcing cable over-bend.
• 646 lb Rated Weight: A 646 lb weight figure indicates the enclosure itself is a heavy-gauge, commercial-grade steel frame — not a light-duty unit. Plan your flooring and transport logistics accordingly: raised-floor tiles typically require weight distribution plates for loads this heavy, and you will need a proper pallet jack or equipment dolly rated for that payload during installation.
• Rack Mount Configuration: Designed for rack mount deployment, which means it integrates into standard data center row layouts with adjacent enclosures, supports structured cabling overhead or underfloor, and accepts standard 19-inch rack-mounted equipment per EIA-310 mounting rails.
• Black Finish: The black finish is standard for modern data center aesthetics and minimizes light reflection in lit server rooms, which matters when you are using visual management indicators (LED status lights, patch panel color coding) to diagnose at a glance across a row.
• Shock Crate Packaging: The GL42UEX-80120B-MS-SC ships in a shock crate — a purpose-built protective shipping container that absorbs transport vibration and impact. For a 646 lb steel enclosure traveling freight, this is the correct packaging specification: standard palletized cardboard shipping is not adequate for a unit this heavy, and an enclosure that arrives with bent rails or damaged mounting strips is a job-site delay.

Integration & Compatibility

The Vertiv EX series is designed to integrate with standard 19-inch rack-mounted equipment per EIA-310 mounting specifications. The 800mm x 1200mm footprint fits within standard data center hot/cold aisle layouts. For power distribution inside the enclosure, pair with a rack PDU matched to your circuit amperage and outlet count requirements — vertical PDUs mount cleanly in the rear column of a 1200mm-deep enclosure without blocking cable access. Review your floor loading calculations before final placement; at 646 lbs for the enclosure alone, fully populated with servers, storage, and switching the total rack weight will exceed 1,500 lbs in most configurations. Explore rack PDUs and power distribution for compatible in-rack power hardware, and see our server rack enclosures category for the full Vertiv EX lineup and comparable alternatives. For structured cabling planning adjacent to this enclosure, the structured cabling and patch panels category covers horizontal and vertical management options that suit 800mm-wide racks.

Frequently Asked Questions

Q: What is the rack unit capacity of the GL42UEX-80120B-MS-SC?

A: The GL42UEX-80120B-MS-SC provides 42U of usable rack space, suitable for fully populating a standard server bay with a mix of 1U, 2U, and larger equipment.

Q: What are the external dimensions of the GL42UEX-80120B-MS-SC?

A: The enclosure is 800mm wide by 1200mm deep. Height follows standard 42U rack dimensions. The 800mm width accommodates wider server chassis and side cable management, while the 1200mm depth handles full-depth servers and rear PDU mounting without clearance issues.

Q: How is the GL42UEX-80120B-MS-SC shipped?

A: It ships in a shock crate — a purpose-built freight container designed to protect the enclosure from transport vibration and impact. Given the 646 lb unit weight, shock-crate packaging is appropriate for preventing rail damage or frame deformation during freight delivery.

Q: How much does the GL42UEX-80120B-MS-SC weigh?

A: The enclosure weighs 646 lbs. Plan for proper material handling equipment — a pallet jack or equipment dolly rated for that load — and verify your raised floor or structural floor rating before placement. Fully populated rack weight will significantly exceed this figure.

Q: Is the GL42UEX-80120B-MS-SC compatible with standard 19-inch rack equipment?

A: Yes. The Vertiv EX series is built to EIA-310 standards for 19-inch rack-mount equipment, compatible with standard 1U through 12U chassis, patch panels, cable management arms, and vertical PDUs used in data center environments.

Ted Perry

The GL42UEX-80120B-MS-SC is a specification I recommend when clients are planning a high-density compute row and need an enclosure that genuinely accommodates full-depth infrastructure — the 1200mm depth is the deciding spec here. I have seen too many builds spec a 900mm rack to save floor space, then fight rear clearance issues when blade enclosures and cabling fill the bay. At 800mm wide and 1200mm deep, this unit removes both constraints in a single configuration.

Technical Highlights:

• 1200mm Depth: Handles full-depth servers (typically 700–900mm chassis) plus rear PDU columns and structured cabling trays without forcing cable over-bend or blocking rear access for hot-swap drives.
• 800mm Width: Meets the minimum width specification for many blade server enclosures and allows side-by-side vertical cable managers to run cleanly without impinging on equipment mounting rails.
• Shock Crate Packaging: At 646 lbs, the enclosure is freight-class by any definition. The shock crate is not optional packaging — it is the correct spec for a steel frame this heavy traveling LTL or intermodal freight, where pallet drops and dock impacts are routine.

Deployment Considerations:

• Verify raised-floor tile load ratings before finalizing placement — 646 lbs empty means a fully populated rack will likely exceed 1,500 lbs total, which exceeds standard 1,000 lb tile ratings in older raised-floor installations.
• Plan for proper rigging equipment on the receiving end; this unit cannot be hand-bombed off a freight dock safely. A pallet jack rated for the full loaded weight and a clear path to the final position need to be confirmed before delivery.

This enclosure is the right specification for a greenfield enterprise data center build or a major rack refresh in a colocation environment where full-depth server hardware, structured rear cabling, and long service life are requirements — not a light-duty IT closet deployment where a shallower, lighter unit would serve just as well at lower cost.
