Vertiv GL45UG2EZ-3048-B-MSS 45U Seismic Server Rack Enclosure
Overview
The Vertiv GL45UG2EZ-3048-B-MSS is a 45U seismic-rated rack enclosure built for data centers, server rooms, and network closets where floor-mount stability under seismic load conditions is a site requirement. At 30 inches wide and 48.4 inches deep, it accommodates modern high-density switching and server equipment without the depth compromises that come with shallow enclosures. If you're specifying for a California, Pacific Northwest, or other seismically active deployment, the EZ Seismic designation targets exactly that use case — standard open-frame or non-rated enclosures won't satisfy the relevant building codes in those jurisdictions.

Key Features
- 45U Usable Height: 45U gives you meaningful headroom over the common 42U baseline — roughly three additional rack units for patch panels, blanking plates, or PDU placement without fighting for space at the top or bottom of the enclosure.
- 30-Inch Width: The 30-inch wide footprint is the standard choice for server rack enclosures in most enterprise deployments; it clears standard floor tile grids and accommodates wide-body switches and UPS units that won't fit in 24-inch frames. If your floor plan is constrained, confirm aisle clearance before ordering.
- 48.4-Inch Depth: Nearly four feet of internal depth handles today's deep 1U servers and 2U storage nodes without forcing cable-management compromises at the rear. Most 1U/2U rack-mount appliances ship with a 28–32-inch chassis — the extra depth leaves real room for structured rear cabling and vertical PDUs.
- Seismic Rating (EZ Seismic): The EZ Seismic designation means this enclosure is engineered to meet seismic performance requirements — relevant for facilities that must comply with GR-63-CORE Zone 4 or equivalent local codes. A non-rated rack in a seismic zone is a liability, not just an engineering gap.
- Black Finish: The GL45UG2EZ-3048-B-MSS ships in black — the standard for most data center and network infrastructure environments. Vertiv also offers the EZ Seismic line in Winter White and Clear configurations for lab or clean-room deployments where visual contrast or aesthetics matter.
Integration and Compatibility
The GL45UG2EZ-3048-B-MSS (often searched as GL45UG2EZ 3048 B MSS) is designed to accept standard 19-inch rack-mount equipment across IT, security, and AV categories. Pair it with rack-mount UPS units and structured cabling to build a complete infrastructure stack. Verify that your heaviest equipment fits within the enclosure's rated static and seismic load capacity — confirm with the Vertiv EZ Seismic datasheet for your specific site's seismic zone before finalizing the equipment manifest.
