Vertiv GL45UG2EZ-2442-W-MSS 45U EZ Seismic Server Rack Enclosure
Overview
The Vertiv GL45UG2EZ-2442-W-MSS is a 45U EZ-series seismic rack enclosure finished in Winter White, designed for data center and network equipment deployments where floor space, structural compliance, and equipment density all matter. At 24 inches wide and 42.4 inches deep, it fits into constrained floor plans while still accommodating full-depth servers and network gear. The GL45UG2EZ-2442-W-MSS (often searched as GL45UG2EZ 2442 W MSS) is part of Vertiv's broader EZ seismic rack family, which spans multiple height, width, depth, and color configurations — giving you flexibility to standardize across a mixed-density environment without sourcing from multiple vendors.

Key Features
- 45U usable height: 45U of rack space in a single enclosure handles high-density compute, storage, and networking stacks — reducing the number of racks required on the floor and cutting per-U footprint cost in medium-density deployments.
- 24-inch width: The 24-inch form factor fits tighter aisle configurations and network closets where the standard 30-inch frame won't clear — useful in edge deployments, IDF closets, and satellite equipment rooms without requiring a floor plan redesign.
- 42.4-inch depth: At 42.4 inches, the enclosure accommodates full-depth 1U and 2U servers, patch panels, and cable management trays without forcing equipment to overhang the rear door — keeping airflow paths clean and doors functional.
- Winter White finish: The Winter White color option integrates cleanly into office-adjacent or lab environments where black enclosures would stand out. It also makes cable tracing and equipment labeling visually easier in well-lit spaces.
- EZ seismic rating: Seismic-rated construction means this rack is engineered to maintain structural integrity during seismic events — a requirement for facilities in Zone 4 seismic regions and often mandated by insurance or local building codes for critical infrastructure rooms.
- Family configurability: The GL45UG2EZ line is available in 42U, 45U, 48U, and 52U heights; 24-inch and 30-inch widths; 42-inch and 48-inch depths; and Black, Winter White, or Clear finishes — so you can match an exact spec across multiple racks in the same row without mixing enclosure generations.
Integration and Compatibility
As part of the Vertiv EZ seismic server rack enclosure family, the GL45UG2EZ-2442-W-MSS is designed to accept standard 19-inch rack-mount equipment. The 45U height and 24-inch width are EIA-310 standard, meaning your existing rack-mount servers, switches, patch panels, UPS units, and cable managers will mount without adapter hardware. Pair this enclosure with a compatible rack PDU and a managed network switch for a complete, organized equipment stack. For high-density thermal environments, verify that your cooling strategy — whether in-row, top-of-rack, or room-level CRAC — is sized for the heat load of 45U at full population before finalizing the floor plan.
Frequently Asked Questions
Q: What rack unit height is the GL45UG2EZ-2442-W-MSS?
A: The GL45UG2EZ-2442-W-MSS provides 45U of usable rack space.
Q: What are the width and depth dimensions of this enclosure?
A: This configuration is 24 inches wide and 42.4 inches deep, fitting standard EIA-310 19-inch rack-mount equipment.
Q: Is this rack available in other sizes or colors?
A: Yes. The EZ seismic family covers 42U, 45U, 48U, and 52U heights; 24-inch and 30-inch widths; 42-inch and 48-inch depths; and Black, Winter White, or Clear finishes. Select the GL45UG2EZ variant that matches your floor plan and aesthetic requirements.
Q: What does the EZ seismic rating mean for this rack?
A: EZ seismic indicates the enclosure is engineered and rated to withstand seismic activity — important for facilities in earthquake-prone regions or where local codes and insurance requirements mandate seismic-rated infrastructure.
Q: Will standard 19-inch rack-mount equipment fit in this enclosure?
A: Yes. The GL45UG2EZ-2442-W-MSS conforms to EIA-310 standards, so standard 19-inch servers, switches, UPS units, and patch panels mount directly without adapter hardware.
When I spec the GL45UG2EZ-2442-W-MSS for a project, the detail I lead with is the 24-inch width combined with the 42.4-inch depth — that pairing is what makes this enclosure viable in edge rooms and IDF closets where a 30-inch-wide frame simply doesn't fit the aisle layout, yet you still need to house full-depth 1U compute or a deep UPS chassis without the rear door hanging open.
Technical Highlights:
- 45U capacity: Forty-five rack units in a single enclosure lets you consolidate a typical IDF stack — top-of-rack switch, patch panels, servers, and a 2U UPS — into one frame rather than splitting across two shallower racks and doubling your footprint.
- 24-inch width: The narrower 24-inch frame clears tight aisle widths and fits within the dimensional envelope of most prefab equipment rooms and modular edge deployments where 30-inch frames require a floor plan exception.
- EZ seismic construction: Seismic-rated enclosures are frequently a hard requirement in California, Pacific Northwest, and other Zone 4 regions — specifying the GL45UG2EZ line from the start avoids costly mid-project substitutions when the structural review flags a non-rated frame.
Deployment Considerations:
- Verify ceiling height clearance before ordering — a 45U enclosure with cable management overhead and a top-mounted cooling unit can exceed standard drop-ceiling heights in older office-adjacent equipment rooms.
- The Winter White finish, while clean in lab and office environments, shows scuffs and cable rub marks more visibly than black — factor that into your maintenance and access frequency expectations for the site.
The GL45UG2EZ-2442-W-MSS is a strong fit for edge data center buildouts, university IDF closets, and any seismic-zone deployment where a compact 24-inch footprint and structural certification are both non-negotiable requirements.
