Vertiv GL52UG2EZ-3042-W-MSS 52U EZ Seismic Open-Frame Rack Enclosure
Overview
The Vertiv GL52UG2EZ-3042-W-MSS is a 52U seismic-rated rack enclosure built for deployments where vibration tolerance is a hard requirement — think California data centers, broadcast facilities, and enterprise server rooms in seismically active zones. At 30 inches wide and 42 inches deep, this unit accommodates standard 19-inch rackmount equipment while providing the lateral bracing and anchoring geometry that EZ Seismic certification demands. The Winter White finish is specified here, making it a practical choice for open office infrastructure rooms or broadcast environments where aesthetics matter alongside compliance.
The GL52UG2EZ-3042-W-MSS is part of Vertiv's Vertiv rack infrastructure line, which spans multiple height, width, and depth configurations — 42U through 52U heights and 24-inch or 30-inch widths — so if your space or load plan calls for a different footprint, the family covers it. For context on selecting the right rack for a structured cabling or server deployment, see the server racks and enclosures category for the full range of options.
Key Features
- 52U capacity: Maximizes vertical density in a single footprint — 52U accommodates a full stack of 1U/2U servers, patch panels, and PDUs without splitting across multiple enclosures, which simplifies cable management and reduces floor space consumption.
- 30-inch width: The 30-inch form factor provides clearance for side-routed power and data cabling, which matters when you're running high-density copper or fiber bundles alongside rackmount equipment. Tighter 24-inch racks can force awkward cable bends at the frame.
- 42-inch depth: Fits most 1U–4U servers and storage appliances with room for rear cable dressing. Check your deepest chassis measurement before ordering — some high-density storage units exceed 40 inches and require a 48-inch-depth variant.
- EZ Seismic rating: Meets seismic compliance requirements for installations in Zone 4 environments, eliminating the need for costly third-party bracing kits and ensuring the rack qualifies for occupancy permits in jurisdictions with strict structural codes.
- Winter White finish: The GL52UG2EZ-3042-W-MSS ships in Winter White — useful for open-plan or co-located infrastructure rooms where a black rack reads as obtrusive. If the installation environment calls for black, the same family is available in that finish.
Integration and Compatibility
This enclosure accepts standard 19-inch rackmount equipment across all U positions. The EZ Seismic frame design integrates with Vertiv's own PDU and power distribution accessories and is compatible with third-party cable management arms and horizontal lacing bars. Confirm your floor-anchor hardware matches local seismic code requirements before commissioning — the rack's seismic rating assumes proper anchor installation per Vertiv's installation guide.
Frequently Asked Questions
Q: What is the U height of the GL52UG2EZ-3042-W-MSS?
A: This specific configuration is the 52U variant, providing 52 rack units of usable mounting space.
Q: What width and depth does the GL52UG2EZ-3042-W-MSS ship in?
A: The GL52UG2EZ-3042-W-MSS is 30 inches wide and 42 inches deep.
Q: What color is the GL52UG2EZ-3042-W-MSS?
A: This model ships in Winter White. The same EZ Seismic family is available in Black if your installation requires it.
Q: Is the GL52UG2EZ-3042-W-MSS suitable for seismically active regions?
A: Yes. The EZ Seismic designation indicates this rack meets seismic zone requirements, making it appropriate for data centers and server rooms in high-seismic-activity areas. Verify that anchor hardware and installation method comply with local building codes for full compliance.
Q: Can I order the GL52UG2EZ-3042-W-MSS in a different height or depth?
A: The Vertiv EZ Seismic family covers multiple configurations including 42U, 45U, 48U, and 52U heights, and 42-inch or 48-inch depths. Contact pre-sales engineering to confirm the right configuration for your floor plan and load requirements.
The GL52UG2EZ-3042-W-MSS is Vertiv's 52U EZ Seismic rack in the 30-inch-wide, 42-inch-deep footprint — the configuration I'd specify first for a mid-size server room in a seismic zone where you need to maximize density without splitting across two enclosures. The 52U height gives you room to grow: full switch stack, patch panels, and a row of 2U compute nodes without immediately hitting the ceiling.
Technical Highlights:
- 52U height: At 52U, this rack holds more equipment per square foot of raised floor than the 42U or 45U variants in the same family — meaningful when your data center charges per-tile or your server room simply has a fixed footprint.
- 30" x 42" footprint: The 30-inch width accommodates side-cable routing without forcing 90-degree bends on patch cables. The 42-inch depth fits most 1U–3U servers comfortably; if you're deploying 4U storage units with deep PSU sleds, measure the chassis first — 48-inch-depth variants exist in the family.
- EZ Seismic construction: Seismic certification removes a permitting hurdle in Zone 4 jurisdictions — you're not bolting on an aftermarket brace kit or commissioning a structural engineer to sign off on a non-rated enclosure.
Deployment Considerations:
- Floor anchoring is mandatory for the seismic rating to be valid — confirm your raised floor or concrete slab can accept the anchor hardware specified in Vertiv's installation guide before the rack ships to site.
- Winter White is the finish on this SKU; if the rest of your rack row is black, order the matching color variant — mixing finishes in an open data center or IDF closet creates a maintenance headache when technicians need to identify equipment by row or bay.
The GL52UG2EZ-3042-W-MSS is the right call for enterprise IDF rooms and data center deployments in seismically active regions where a non-certified rack would fail the building inspector — not a rack to specify for a closet install where seismic compliance isn't required and the cost premium isn't justified.
