Vertiv GL45UG2EZ-2442-B-MSS 45U EZ Seismic Open Frame Server Rack Enclosure
Overview
The Vertiv GL45UG2EZ-2442-B-MSS is a 45U seismic-rated rack enclosure built for data centers, network rooms, and security infrastructure deployments where equipment must stay anchored and operational through seismic events. At 24 inches wide and 42 inches deep in a black finish, this unit fits standard two-post and four-post rack layouts while meeting the EZ Seismic specification — a practical requirement for installations in California, the Pacific Northwest, Japan, or any jurisdiction with seismic code enforcement. If you are specifying racks for a government facility, healthcare campus, or telecom central office in a seismic zone, this is the configuration to evaluate. For Vertiv rack enclosures and power infrastructure, this model sits in the mid-tier of the EZ Seismic line.
Key Features
- 45U Usable Height: 45U of rack space provides room for dense server, NVR, switch, and patch panel stacking without forcing a second cabinet. In a physical security head-end room with IP cameras feeding multiple NVRs plus a core switch and UPS, 45U typically covers the full stack in a single enclosure — fewer cabinets means simpler cable management and a smaller footprint.
- 24-Inch Cabinet Width: The 24-inch width (GL45UG2EZ-2442-B-MSS) fits standard 19-inch rack-mount equipment with adequate side clearance for airflow and cable dressing. This is the narrower of the two width options in the EZ Seismic family — useful when aisle width or room dimensions are constrained, as in retrofit IDF closets or modular security operations centers.
- 42-Inch Depth: A 42-inch interior depth accommodates full-depth 1U/2U servers and deep UPS units without the rear door pressure issues that come with undersized enclosures. Most 2U rack-mount NVRs and 1U managed PoE switches fit comfortably with room for rear cable runs.
- EZ Seismic Rating: The EZ Seismic designation means this enclosure has been engineered and tested to resist lateral seismic loads — not just a marketing label. Facilities in seismic zones often require Zone 4 or GR-63-CORE NEBS compliance from their rack infrastructure. Confirm the specific seismic test standard with Vertiv documentation for your jurisdiction's code requirement before specifying.
- Black Finish: The black powder-coat finish (the -B suffix in GL45UG2EZ-2442-B-MSS) is the standard for data center and server room environments. It blends with existing rack infrastructure and does not show dust accumulation the way lighter finishes do — a minor but real operational consideration in active equipment rooms.
- Vertiv EZ Seismic Family Scalability: The EZ Seismic line spans multiple heights (42U through 52U) and widths (24-inch and 30-inch), so if future capacity planning calls for a taller or wider enclosure, you can maintain a consistent seismic-rated infrastructure without switching vendors or qualification processes. Standardizing on a single rack family simplifies spare parts, door kits, and PDU accessory sourcing.
Integration and Compatibility
This enclosure is designed to accept standard 19-inch EIA-310 rack-mount equipment. It integrates with Vertiv's own PDU line (including the Geist and Liebert families), allowing in-rack power distribution and remote monitoring when paired with a networked PDU. For network infrastructure deployments, the 42-inch depth supports full-depth switches from major vendors without modification. Cable management accessories, blanking panels, and seismic anchor kits are sourced through the Vertiv accessory ecosystem — confirm part numbers with Vertiv for the specific floor-mounting hardware required in your seismic zone. Integrators specifying this rack alongside rack-mount UPS units should verify total loaded weight against the seismic anchor kit's floor-load rating before commissioning. For broader server rack and enclosure selection guidance, compare this model against the 30-inch wide variant if your PDU or cable tray layout requires additional horizontal clearance.
Frequently Asked Questions
Q: What does the EZ Seismic designation mean on the GL45UG2EZ-2442-B-MSS?
A: EZ Seismic indicates this enclosure has been designed and tested to withstand seismic lateral loads. It is intended for deployments in seismic zones where rack enclosures must meet specific structural performance standards. Confirm the exact test standard (such as GR-63-CORE NEBS or Zone 4) with Vertiv documentation for your jurisdiction's compliance requirement.
Q: What rack unit capacity does the GL45UG2EZ-2442-B-MSS provide?
A: This enclosure provides 45U of usable rack space, sufficient to house a full security infrastructure head-end stack including NVRs, managed switches, patch panels, and a rack-mount UPS in a single cabinet.
Q: What are the interior dimensions of this rack?
A: The GL45UG2EZ-2442-B-MSS is 24 inches wide and 42 inches deep, accommodating standard 19-inch EIA-310 rack-mount equipment. The 42-inch depth handles full-depth servers and UPS units without rear door interference.
Q: Is this enclosure compatible with Vertiv PDUs?
A: Yes, the EZ Seismic enclosure family is designed to integrate with Vertiv's PDU product line, including Geist and Liebert rack PDUs. Specific mounting compatibility should be confirmed against Vertiv PDU datasheets for your chosen PDU model.
Q: What finish does the GL45UG2EZ-2442-B-MSS come in?
A: This model ships in black powder-coat finish, indicated by the -B suffix in the part number. The EZ Seismic family is also available in Winter White and Clear finishes under separate part numbers.
Q: Does this rack require special floor anchoring for seismic compliance?
A: Seismic-rated enclosures typically require installation with approved floor-anchor kits to achieve their rated seismic performance. Confirm the required anchoring hardware with Vertiv and your local code authority — the enclosure alone does not fulfill seismic compliance without proper anchoring.
When I spec rack infrastructure for seismic-zone deployments — government buildings on the West Coast, hospital data rooms in earthquake-prone regions, telecom facilities in the Pacific Rim — the GL45UG2EZ-2442-B-MSS is one of the configurations I return to. The 45U height and 24-inch width combination is well-suited to mid-size security head-end rooms where you need to consolidate a full NVR stack, switching layer, and UPS into a single footprint without overpowering a smaller IDF space with a 30-inch cabinet.
Technical Highlights:
- 45U Capacity: Handles a realistic physical security stack — two 4U NVRs, a 1U core switch, 2U patch panel, and a 2U UPS — with room to spare for future expansion without a second cabinet.
- 24in × 42in Footprint: The 24-inch width keeps the enclosure within the narrower aisle layouts common in retrofit deployments, while the 42-inch depth eliminates the rear clearance problems that plague shallower cabinets when full-depth UPS units are installed.
- EZ Seismic Construction: Built to resist lateral seismic loads — a hard requirement in California, Oregon, Washington, and international markets with seismic codes. This is not a self-certification; confirm the specific GR-63-CORE or Zone 4 test documentation with Vertiv for your jurisdiction.
Deployment Considerations:
- Floor anchoring is not optional for seismic compliance — the enclosure must be installed with Vertiv-approved anchor hardware to achieve the rated seismic performance. Factor anchor kit lead time into your project schedule.
- The -B (black) finish is correct for most data center and server room environments, but confirm with the facilities team early: some healthcare and government interiors specify white or clear-door enclosures for visual equipment audits.
This enclosure is the right call for physical security infrastructure rooms in seismic zones — specifically, multi-NVR deployments in California or Pacific Northwest commercial buildings where the AHJ requires seismic-rated rack infrastructure and you cannot absorb the schedule risk of a non-compliant enclosure failing inspection.
