Vertiv GL42UEX-80120B-MM-SP 42U Floor-Standing Server Rack

Overview

The Vertiv GL42UEX-80120B-MM-SP is a 42U floor-standing open-frame enclosure from the Vertiv EX Series, built for data center, server room, and network equipment deployments that demand a deep, wide footprint. At 800mm wide and 1200mm deep, this rack provides the lateral and front-to-back clearance to house high-density compute and storage gear — including full-depth servers, large UPS units, and cable-intensive switching equipment that a standard 600mm-deep rack simply cannot accommodate. The unit ships in black and arrives on a shock pallet, protecting the enclosure and any pre-installed hardware from transit vibration and impact damage. Manufactured in the United States, the GL42UEX-80120B-MM-SP is part of the broader Vertiv rack and enclosure catalog, a line built around enterprise data infrastructure requirements.

Key Features

• 42U Usable Height: Forty-two rack units of vertical space handles a full complement of 1U and 2U servers, patch panels, KVM switches, and PDUs without running short mid-build. Plan for approximately 73.5 inches of rail space — enough to populate a complete compute stack in a single enclosure.
• 800mm Width: The 800mm (approximately 31.5 inches) wide footprint accommodates wider blanking panels, side-exit cabling, and equipment that ships in wider chassis formats. It also provides generous clearance for cable managers and vertical PDUs mounted on the interior rail posts without crowding the equipment.
• 1200mm Depth: At 1200mm (approximately 47.2 inches) deep, this rack handles full-depth servers — including high-density storage arrays and large UPS units that routinely exceed 900mm in chassis depth. If your equipment list includes any 1000mm-class servers or dual-corded PDU configurations, the 1200mm depth eliminates the clearance compromise you'd face in a shallower enclosure.
• Floor-Standing Form Factor: This is a self-supporting, free-standing enclosure — no wall attachment required. Position it independently on a raised floor, concrete slab, or standard server room tile. Relevant for deployments where seismic or wall-anchoring constraints limit options.
• Shock Pallet Packaging: The GL42UEX-80120B-MM-SP ships on a shock pallet, meaning the enclosure arrives with mechanical isolation from freight impact and vibration. For remote deployments, co-location drops, or facilities where equipment travels long distances before installation, this packaging protects the enclosure structure and any pre-staged hardware from damage in transit.
• Black Finish: The all-black finish blends into standard data center aesthetics and does not require color-coordination with mixed-vendor rack rows. A practical consideration in co-location environments where visual consistency matters.
• US Manufactured: Built domestically — a relevant procurement consideration for government, defense, or TAA-sensitive deployments that carry country-of-origin requirements. Verify TAA compliance against your specific contract requirements before ordering.
• 646 lbs Structural Rating: At 646 lbs as shipped, this enclosure is built for dense, heavy equipment loads. Verify your raised-floor tile load rating or concrete slab capacity before placing the rack — 42U of fully loaded compute and storage can approach or exceed this figure in high-density configurations.

Integration and Compatibility

The EX Series enclosure is designed to integrate with standard 19-inch rack-mount equipment, the universal format across enterprise networking, compute, and storage gear. The 800mm interior width and 1200mm depth provide mounting compatibility with equipment from all major server, switch, and storage vendors. For organizations building out structured server rack infrastructure, this unit pairs naturally with vertical and horizontal cable management accessories, blanking panels, and rack-mount PDUs. When planning power distribution inside the enclosure, review your PDU depth spec against the 1200mm available interior depth — zero-U vertical PDUs typically require 50–75mm of rear clearance that this enclosure readily provides. For high-density deployments requiring UPS integration, the 1200mm depth accommodates most 2U and 3U rack-mount UPS units without compromise. For large-scale deployments, review the data center infrastructure category for complementary enclosures, cable managers, and cooling accessories.

Frequently Asked Questions

Q: What is the usable internal depth of the GL42UEX-80120B-MM-SP?

A: The enclosure has a nominal external depth of 1200mm. Usable internal depth between front and rear mounting rails will be less — typically 900–1000mm depending on rail configuration. Verify the specific internal rail-to-rail dimension in the Vertiv EX Series technical documentation before ordering equipment with depth near the maximum.

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

A: Yes. The EX Series enclosure is built around the standard 19-inch rack form factor, compatible with virtually all server, networking, and storage equipment manufactured to EIA-310 standards.

Q: Why does the GL42UEX-80120B-MM-SP ship on a shock pallet?

A: The shock pallet provides mechanical isolation during freight transit, protecting the enclosure structure and any pre-staged components from vibration and impact damage. This is particularly valuable for long-haul shipments or when the rack is pre-populated before delivery.

Q: What is the weight of the GL42UEX-80120B-MM-SP?

A: The unit weighs 646 lbs as packaged. Plan your floor load capacity accordingly — both the enclosure weight and the intended equipment payload must fall within your raised-floor or slab rating.

Q: Is the GL42UEX-80120B-MM-SP manufactured in the United States?

A: Yes, the country of origin is listed as the United States. For TAA-compliance verification under specific government contract requirements, confirm against your contract's applicable clauses and Vertiv's current product documentation.

Q: What width and depth should I compare when selecting between this rack and a narrower or shallower model?

A: This enclosure is 800mm wide and 1200mm deep. If your equipment list does not include full-depth servers or wide chassis gear, a 600mm-wide or 1000mm-deep variant may reduce your footprint and cost. Choose the 800x1200mm configuration when your equipment depth, cabling volume, or PDU layout demands the extra clearance.

The GL42UEX-80120B-MM-SP is one of those racks that earns its keep the moment your equipment list includes anything deeper than 900mm — and that describes most modern high-density compute deployments. The 1200mm depth spec is the number to keep in mind: it's not just about fitting the server, it's about fitting the server plus cable managers, PDU rails, and the 75–100mm of rear clearance your cooling airflow needs to exit cleanly.

Technical Highlights:

• 1200mm Depth: Handles full-depth servers, dual-corded PDU configurations, and rear cable management without the clearance compromises you'd face in a 1000mm or shallower enclosure — the extra depth pays for itself in a single dense rack build.
• 800mm Width: Wide enough to accommodate side-exit cabling troughs, vertical PDU mounting, and wider 2-post accessories without forcing equipment into the airflow path — relevant in high-density rows where cabling discipline directly affects thermals.
• Shock Pallet Packaging: Pre-staged racks or racks shipped to remote facilities benefit measurably from shock-isolated freight handling — one avoided re-rack event covers the cost difference versus standard palletized shipping.

Deployment Considerations:

• At 646 lbs packaged, confirm your receiving dock has appropriate material handling equipment before the freight arrives — a fully loaded 42U rack can easily exceed 1,500 lbs in final configuration, so floor load planning should happen before rack placement, not after.
• The EX Series shock pallet is a one-time use transit feature — it does not substitute for seismic anchoring or anti-tip restraints required by code in earthquake-zone facilities; install appropriate floor anchoring hardware after positioning.

This enclosure is the right call for a purpose-built high-density compute row in a co-location or enterprise data center where equipment depth, cabling volume, and transit integrity are all first-order concerns — not an afterthought.
