Vertiv GL45UG2EZ-3048-W-MSS EZ Seismic 45U Server Rack Enclosure
Overview
The Vertiv GL45UG2EZ-3048-W-MSS is a 45U EZ Seismic rack enclosure configured at 30 inches wide and 48.4 inches deep in Winter White — a purpose-built cabinet for environments where seismic compliance, physical footprint, and equipment depth all matter. Whether you're deploying in a California Tier III data center, a Pacific Northwest network room, or any facility subject to GR-63-CORE or similar seismic zone requirements, the EZ Seismic line is Vertiv's answer to that specific constraint. The GL45UG2EZ-3048-W-MSS (often searched as GL45UG2EZ 3048 W MSS) fits that specification in a 45U column at 30" wide — matching most standard server and networking equipment without eating into valuable floor space with unnecessary cabinet width.
Key Features
- 45U Usable Height: 45U gives you meaningful headroom above a standard 42U baseline — room for a few extra 1U patch panels, a PDU, or a cable management tray without forcing a second cabinet. In dense deployments, those three extra units matter.
- 30-Inch Cabinet Width: The 30" footprint fits most server aisles designed around 24" or 30" standards. If your row layout uses 30" cabinets throughout, this slots in without disrupting your hot/cold aisle spacing or overhead cable management alignment.
- 48.4-Inch Usable Depth: A 48" interior depth accommodates most modern 1U/2U rack-mount servers (typically 26–32" deep) plus front and rear cable management — without the oversized 54" depth some facilities can't accommodate structurally.
- Winter White Finish: The Winter White color option is relevant in specific deployments — broadcast facilities, clean-room adjacent environments, and retail back-of-house installations where a black cabinet draws visual attention. It's a practical finish choice for facilities with specific aesthetic or contrast requirements, not a cosmetic upgrade.
- EZ Seismic Design: The EZ Seismic designation indicates this enclosure is built to meet seismic zone compliance requirements — relevant for any installation governed by GR-63-CORE, IBC, or state-level seismic codes. Seismic-rated cabinets aren't just about earthquakes; they're often a hard procurement requirement in regulated facility types regardless of geographic risk.
Integration and Compatibility
The GL45UG2EZ-3048-W-MSS is compatible with standard 19-inch EIA rack-mount equipment. The 30" wide, 48.4" deep cabinet geometry is designed to integrate with Vertiv's PDU, cable management, and airflow accessory ecosystem. Confirm accessory rail compatibility and door/side-panel configurations with your Vertiv account team before finalizing the order, as the EZ Seismic line offers multiple configuration options within the same chassis family.
Frequently Asked Questions
Q: What does the EZ Seismic designation mean on the GL45UG2EZ-3048-W-MSS?
A: The EZ Seismic designation indicates the enclosure is engineered to meet seismic zone compliance requirements such as GR-63-CORE, which is commonly required in regulated data centers and facilities in seismic risk zones. It is a procurement-relevant specification, not just a geographic consideration.
Q: Is the GL45UG2EZ-3048-W-MSS 30 inches wide or 24 inches wide?
A: This specific SKU is 30 inches wide and 48.4 inches deep at 45U height. The Vertiv EZ Seismic family also includes 24-inch wide and alternative depth configurations — verify the SKU carefully before ordering.
Q: What color is the GL45UG2EZ-3048-W-MSS?
A: This configuration ships in Winter White. The EZ Seismic family is also available in Black — confirm the color suffix in the SKU if color matching to an existing row is required.
Q: What rack unit height is included in this enclosure?
A: The GL45UG2EZ-3048-W-MSS provides 45U of rack space. The EZ Seismic family spans 42U, 45U, 48U, and 52U options — select based on your equipment count plus growth headroom.
The GL45UG2EZ-3048-W-MSS sits in the part of the Vertiv EZ Seismic lineup that gets specified most often in mixed-use network rooms: 45U at 30" wide gives you the column height to stack a meaningful equipment load without forcing a 42U compromise, and the 48.4" depth covers virtually every rackmount chassis on the market without the floor-space penalty of a 54" cabinet. The Winter White finish is a real differentiator in the handful of facility types where it matters — broadcast racks, medical-adjacent installations, or any environment where a black column looks out of place.
Technical Highlights:
- 45U vs 42U headroom: Three extra units may sound minor, but in practice they absorb a 2U KVM, a 1U patch panel, or a cable manager that would otherwise force a second cabinet — a meaningful cost and footprint difference in dense deployments.
- 30" wide footprint: Aligns with the most common aisle-width planning standard for mid-to-large data hall rows. Facilities designed around 24" cabinets will need to verify row fit before ordering this SKU.
- 48.4" usable depth: Sufficient for modern 2U servers (typically 26–32" chassis) with front and rear cable management clearance maintained — avoids the structural complications of 54" deep cabinets in older facilities with tight slab-to-slab constraints.
Deployment Considerations:
- The EZ Seismic family spans 42U through 52U in both 24" and 30" widths — double-check the full SKU string before procurement if your facility has mixed cabinet heights in the same row, as GL45UG2EZ-3048-W-MSS is specifically the 45U/30"/48" variant.
- Winter White finish limits refinishing and touch-up options compared to standard Black — if the installation environment involves ongoing construction or heavy equipment movement nearby, consider whether the finish is durable enough for the specific site conditions.
This enclosure is the right call for seismic-zone data centers and regulated network rooms where GR-63-CORE compliance is a hard procurement gate and the 30" wide, 45U column geometry fits the existing row plan — particularly in facilities where Winter White cabinet rows are already standardized.
