Vertiv VR Rack VR3357: 48U 800x1200mm 19-Inch Server Cabinet

Introducing the Vertiv VR Rack VR3357, a purpose-built 48U server rack enclosure engineered for reliability, scalability, and straightforward configuration in professional data centers, telecom rooms, and IT closets. This 19-inch cabinet, sized at 2265mm in height with an 800mm width and 1200mm depth, is designed to handle dense equipment deployments without sacrificing accessibility or airflow. The standout feature of the VR3357 is its deep frame, which delivers approximately 2.5 inches more usable depth than similarly sized racks. That extra depth translates into more room behind front-mounted devices for cable management, power distribution, and cooling pathways, reducing clutter, easing maintenance, and helping preserve optimal airflow through the cabinet. In practical terms, you can install more blades, more storage, and more network gear in a single enclosure while keeping cables organized, ports clearly labeled, and equipment within easy reach for upgrades and servicing. The VR3357 embodies Vertiv’s philosophy of robust engineering paired with simple, repeatable configuration—so you can deploy a scalable rack solution quickly, without compromising on strength, security, or serviceability.

• High-capacity 48U enclosure: The VR3357 provides substantial vertical space to house a broad mix of servers, storage arrays, switches, routers, PDUs, KVM modules, and other 19-inch rack-mount equipment. With 48U at your disposal, you can consolidate multiple workloads into one durable cabinet, streamline cabling, and reduce the footprint of your data center floor plan. This capacity is especially valuable in environments that require future-proofing, where you anticipate adding density over time or combining compute and storage within a single enclosure to minimize latency and improve management efficiency.
• Precise footprint for dense environments: The cabinet’s exterior dimensions—2265mm in height, 800mm in width, and 1200mm in depth—are tailored for data centers that demand a compact footprint without sacrificing interior volume. The 800x1200mm footprint fits within standard room layouts while delivering generous interior space for long-length cable runs and modular components. The result is a balance between space efficiency and maximum rack density, enabling operators to optimize cooling, cable routing, and service access with confidence.
• Deep frame for enhanced usability: A distinctive advantage of the VR3357 is its deep frame, which provides around 2.5 inches more usable depth than similar-sized racks. This extra space improves back-of-rack cable management, makes it easier to route power and data cabling without crowding, and supports deeper equipment configurations that might include larger power supplies or multi-port connectivity. The additional depth also reduces the risk of bumped cables when equipment is inserted or removed, helping preserve a clean, organized interior for ongoing maintenance.
• 19-inch mounting standard for broad compatibility: Built around the universal 19-inch rack-mounting standard, the VR3357 is compatible with a wide array of IT devices—from standard servers and disk enclosures to high-density network switches and modular storage rails. This compatibility simplifies procurement and integration, ensures you can source reputable rails and accessories from Vertiv or third-party vendors, and minimizes the time needed to integrate new hardware into your existing environment.
• Designed for easy configuration and maintenance: The VR3357 emphasizes straightforward assembly and intuitive management. Its sturdy construction supports long-term reliability, while access panels, bays, and potential cable-management accessories are arranged for efficient deployment and routine servicing. Whether you’re consolidating gear, performing routine upgrades, or reconfiguring racks to meet evolving workloads, you’ll appreciate the simplified workflow, predictable install times, and consistent performance that come with a purpose-built Vertiv rack system.

How to install Vertiv VR Rack VR3357

• Plan the installation by assessing floor load capacity, ensuring clear front and rear access, and confirming the desired airflow direction for your cooling strategy. Consider the placement of power sources, network uplinks, and any wall or door requirements to keep the rack aligned with facility standards.
• Unpack the VR3357 carefully and inspect all components for shipping damage. Verify that rails, screws, mounting brackets, doors, and panels are present and undamaged before beginning assembly.
• Install or adjust the mounting rails to the cabinet frame. Align the rails with the uprights and set the desired mounting depth to accommodate your equipment. Use the appropriate hardware to secure rails firmly, ensuring stability during device insertion and removal.
• Position the cabinet in the chosen location, then level it and secure it according to site requirements. If floor anchoring is specified or recommended, follow local building codes and facility policies to ensure a safe, stable installation that can withstand operational loads and seismic considerations as applicable.
• Route cables through the front and rear openings, employing cable management accessories to organize bundles, preserve airflow, and simplify future upgrades. Keep power cabling separate from data cabling where possible to minimize interference and to maximize cooling efficiency within the egress paths of the cabinet.
• Mount equipment in a logical sequence—typically starting with heavier, lower-profile devices and moving to lighter, upper units. Connect power and network interfaces as you populate the rack, label cables clearly, and perform a staged functional test to verify connectivity before bringing workloads online. Reassess clearance, airflow, and cable slack after initial commissioning.
