Vertiv VR3105 45U Floor-Standing Server Rack Enclosure
Overview
The Vertiv VR3105 is a 45U, floor-standing open-frame server rack enclosure built for data center deployments, network closets, and security equipment rooms where you need a steel chassis with full 19-inch EIA compatibility. At 600mm wide and 1062.5mm deep, the VR3105 provides enough vertical and horizontal real estate to house edge compute nodes, NVRs, patch panels, and network switching gear without improvising custom mounts. If you're outfitting a network video recorder stack or consolidating IT infrastructure into a managed footprint, this cabinet gives you the structure to do it cleanly.

Key Features
- 45U Capacity: 45 rack units of usable vertical space means you can install a mix of 1U switches, 2U NVRs, and 4U servers in a single enclosure without adding a second cabinet. That's typically enough for a full edge security and networking stack in a mid-size deployment.
- 600 x 1062.5mm Footprint: The 600mm width accommodates standard 19-inch rail-mounted equipment, while the 1062.5mm depth is deep enough to house full-length rack servers and fiber patch management trays without the rear cable tray hanging over the edge.
- Steel Construction: All-steel build means this is a permanent install, not a portable unit. Steel handles the weight of fully populated power strips, UPS modules, and dense networking gear without flex or racking distortion over time — relevant if you're mounting heavy equipment near the top of the unit.
- 19-Inch EIA Rail Standard: Universal 19-inch compatibility means anything rack-mountable you're already running — PoE switches, access control panels, cable management — drops in without adapter plates or custom brackets.
- Floor-Standing Form Factor: Designed to stand independently on a raised floor or concrete slab. No wall anchoring required for standard loads, which simplifies installation in open machine rooms or security operations centers.
- Black Steel Finish: The black powder-coat finish is standard for enclosed equipment rooms and blends into most data center and IDF environments without looking out of place in customer-facing areas.
- M6 Cage Nut Hardware Included: Ships with 50x M6 cage nuts and screws, which covers a significant portion of a fully populated 45U cabinet — fewer trips to the hardware store on installation day.
Integration & Compatibility
The VR3105 follows the 19-inch EIA-310 rack standard, making it compatible with the full range of rack-mount equipment from networking, server, AV, and security camera infrastructure vendors. The 45U height and included M6 hardware allow direct mounting of 1U through 4U chassis without additional adapters. For installations requiring cable management, blanking panels, or power distribution, standard 19-inch accessories fit without modification. If you're integrating this into a larger rack infrastructure buildout, the 1062.5mm depth is worth cross-checking against your longest chassis — measure rail-to-rear clearance before finalizing cable routing.

Frequently Asked Questions
Q: What rack unit capacity does the VR3105 support?
A: The VR3105 provides 45U of usable rack space, accommodating standard 19-inch EIA-310 rail-mounted equipment from 1U to multi-unit chassis.
Q: What are the external dimensions of the VR3105?
A: The VR3105 is 600mm wide and 1062.5mm deep. It is a floor-standing enclosure — verify floor clearance and door swing before finalizing placement.
Q: Does the VR3105 include mounting hardware?
A: Yes. The VR3105 ships with 50 M6 cage nuts and screws, sufficient to populate a significant portion of the cabinet without ordering additional hardware separately.
Q: What rail standard does the VR3105 use?
A: The VR3105 uses the standard 19-inch EIA rack rail format, compatible with the vast majority of enterprise networking, server, and security equipment.
Q: Is the VR3105 open-frame or enclosed?
A: The VR3105 is a floor-standing rack enclosure. Verify the specific door and panel configuration for your environment with Vertiv documentation, as enclosure options vary within the VR series.
Q: What is the VR3105 made of?
A: The VR3105 is constructed of steel with a black finish, suitable for permanent installation in equipment rooms, data centers, and network closets.
When I spec a rack for a multi-NVR or edge compute deployment, the first numbers I check are depth and U-count. The VR3105 clears both bars — 45U gives you enough vertical space to handle a full security infrastructure stack, and the 1062.5mm depth means you're not fighting rear cable management with full-depth servers hanging off the back rails.
Technical Highlights:
- 45U Vertical Capacity: At 45U, this cabinet can house a full mixed stack — NVRs, PoE switches, access control panels, patch management — without spilling into a second enclosure. That matters when you're working in a restricted IDF closet and don't have floor space for two units.
- 600mm Width with 19-inch EIA Rails: Standard 600mm cabinet width with 19-inch rail spacing means zero adapter work. Every EIA-compliant rack device mounts directly — no custom brackets, no shimming.
- Steel Build with 50x M6 Hardware Included: The all-steel chassis handles the load of a fully populated cabinet, and shipping 50 M6 cage nuts and screws with the unit means your install crew isn't making a hardware run on day one.
Deployment Considerations:
- At 1062.5mm depth, verify that your room's rear wall clearance allows for cable egress — tight equipment rooms can make this a real constraint, especially when you're running structured cabling out the back.
- The VR3105 is floor-standing, not wall-mounted — confirm your floor loading spec before committing to a fully populated build, particularly in older buildings with raised flooring systems that have per-tile weight limits.
The VR3105 is the right call for a permanent security operations center buildout or an IDF room where you need a structured, steel enclosure to consolidate NVRs, switching, and edge compute under one cabinet — not a temporary deployment or a mobile rack application.
