Vertiv GL42UG2EZ-2448-B-MSS 42U Seismic Open-Frame Rack

Overview

The Vertiv GL42UG2EZ-2448-B-MSS is a 42U seismic-rated rack enclosure built for data center and critical infrastructure deployments where standard rack frames are not sufficient. With a 24-inch width and 48.4-inch depth in a black finish, this EZ Seismic configuration is sized to house dense 1U and 2U servers, storage arrays, patch panels, and network switching gear in facilities that require seismic zone compliance. If you are specifying a rack for a California Title 24, Zone 4, or equivalent seismic environment, the GL42UG2EZ-2448-B-MSS is the model to evaluate in the Vertiv EZ Seismic line. The 42U height provides standard full-rack capacity while the 48.4-inch depth accommodates deep servers and cable management without forcing equipment to overhang the rear rail.

Key Features

• 42U Rack Height: Full-rack capacity for dense IT builds — enough vertical space to house servers, storage, top-of-rack switching, and 1U patch panels without compromising airflow paths between units.
• 24-Inch Width: Standard EIA-310 19-inch rail spacing inside a 24-inch wide frame — fits most data center floor tile footprints and standard containment aisle configurations without custom cutouts.
• 48.4-Inch Depth: Accommodates deep 1U/2U servers and NVR appliances that commonly measure 28–32 inches, with room behind for structured cabling, PDU mounting, and rear cable managers.
• Seismic-Rated Construction: The EZ Seismic designation indicates this rack is engineered for seismic zone compliance — relevant for deployments in earthquake-prone regions or facilities bound by building codes that require rated enclosures for IT equipment.
• Black Finish: Standard black powder-coat finish integrates cleanly into mixed-vendor data center rows and security operations center (SOC) environments without visual mismatch.

Integration and Compatibility

The GL42UG2EZ-2448-B-MSS is compatible with standard 19-inch rackmount equipment across the Vertiv server rack and enclosure line as well as third-party networking, storage, and network video recorder appliances that follow EIA-310 rack standards. The 48.4-inch depth suits both shallow-mount patch panels and full-depth 1U/2U servers without adapter kits. For deployments integrating PoE switching and physical security gear, review your PoE switch depth spec before finalizing rail position. Cable management accessories and PDUs mount in the standard Vertiv accessory ecosystem — confirm compatibility by part number before ordering.

This rack is part of the broader seismic server rack category; if your project requires a different height (45U, 48U, or 52U) or width (30-inch), Vertiv offers additional EZ Seismic configurations — verify the exact SKU against your floor plan and seismic zone requirements before ordering, as each dimension combination is a distinct part number.

Frequently Asked Questions

Q: What is the rack unit height of the GL42UG2EZ-2448-B-MSS?

A: The GL42UG2EZ-2448-B-MSS is a 42U rack enclosure. The EZ Seismic line also includes 45U, 48U, and 52U height options in separate SKUs.

Q: What are the width and depth dimensions of this rack?

A: This configuration is 24 inches wide and 48.4 inches deep. Vertiv also offers 30-inch-wide and 42-inch-deep variants in the EZ Seismic family under different part numbers.

Q: Is the GL42UG2EZ-2448-B-MSS suitable for seismic zone 4 or California Title 24 compliance?

A: The EZ Seismic designation indicates seismic-rated construction. For specific zone ratings, certification documentation, and compliance testing results, contact Vertiv or request the product datasheet directly from the manufacturer.

Q: What finish color does this rack ship in?

A: Black powder-coat finish. Vertiv also offers Winter White and Clear finishes in other EZ Seismic configurations.

Q: Can standard 19-inch rackmount equipment be installed in this rack?

A: Yes. The GL42UG2EZ-2448-B-MSS follows EIA-310 19-inch rail standards, compatible with the vast majority of 1U and 2U servers, switches, patch panels, NVRs, and PDUs.

Ted Perry

The GL42UG2EZ-2448-B-MSS sits in a specific niche: a full 42U enclosure with a 48.4-inch depth built to meet seismic compliance requirements. That depth spec matters more than it might seem — most physical security infrastructure, from NVR appliances to server-class VMS hosts, ships at 25–30 inches deep, and you need that extra rear space for structured cabling and PDU arms without bending cables hard against the back panel.

Technical Highlights:

• 48.4-Inch Depth: Deep enough to mount full-length servers and NVR appliances back-to-front with a rear cable manager in place — a detail that eliminates the cable-pinch problems you see when someone installs a 29-inch server in a 36-inch-deep rack.
• 42U Capacity: A full-rack build that handles a mixed security stack — VMS servers, PoE switching, patch panels, and UPS modules — without stacking enclosures or building out a second rack prematurely.
• Seismic-Rated Frame (EZ Seismic): Required in Zone 3/4 jurisdictions and any facility built to IBC seismic provisions — using a non-rated frame in a seismic-code building creates liability exposure regardless of equipment brand.

Deployment Considerations:

• Confirm the exact seismic zone and applicable code (IBC, OSHPD, GR-63) against the Vertiv certification documentation before committing to this SKU — the EZ Seismic line covers multiple zone ratings and the cert paperwork is what the inspector signs off on, not the product name.
• The 24-inch width is correct for most standard floor tile grids, but verify your containment aisle width and any raised-floor cutout dimensions before scheduling delivery — seismic racks ship heavy and are not easy to return once on-site.

This rack is the right call for a new SOC build, colocation cage, or government/healthcare data room in a seismic zone where code compliance is a hard requirement — not an optional upgrade.
