Middle Atlantic R4 Series 52RU 4-Post Rack - 84.2" High, 36" Depth Open-Frame Server Rack

The Middle Atlantic R4CN-5124B open-frame rack is engineered to elevate your networking and IT deployments by offering a robust, open layout that accommodates deeper, heavier components. This 4-post open-frame design provides substantial mounting space and stability for servers, switches, routers, telecom gear, VOIP equipment, and related accessories. With a tall 84.2-inch height and a generous 36-inch depth, the R4 Series delivers ample headroom for expansive rack configurations, streamlined cable management, and reliable airflow—making it an ideal choice for data centers, network closets, broadcast environments, and high-density IT rooms seeking scalable, professional-grade infrastructure.

• Designed to support deeper, heavier equipment: The 52U capacity and four-post open-frame design deliver rock-solid support for larger network devices, high-density servers, telecom chassis, and power distribution units. This configuration minimizes chassis twist and provides a secure mounting platform for heavy components, enabling reliable operation in demanding environments while reducing the risk of hardware strain over time.
• Large footprint for flexible organization: At 84.2 inches tall and 36 inches deep, the rack offers expansive space for multiple devices, including core switches, aggregation routers, patch panels, and serial interfaces. The generous depth also facilitates clean behind-the-equipment cable routing and improved airflow, helping maintain optimal temperatures and easier future upgrades in growing networks or broadcast setups.
• Open-frame versatility and airflow: The open-frame construction promotes unobstructed airflow and straightforward access for installation, maintenance, and upgrades. With no enclosure limiting front-to-back access, technicians can quickly swap components, reconfigure layouts, and implement efficient cable management strategies to support high-performance IT and AV systems.
• Ease of installation and 19-inch compatibility: Built around standard 19-inch rack gear, the R4CN-5124B accepts a wide range of equipment—from servers and switches to patch panels and PDUs—with mounting rails and hardware designed to support common depths. This makes it easy to consolidate gear from multiple vendors into a single, orderly rack while maintaining compatibility with widely used rack-mount components.
• Professional-grade reliability and brand support: Middle Atlantic is renowned for durable, enterprise-grade rack solutions that stand up to demanding data centers, broadcast rooms, and IT closets. The R4 open-frame rack combines rugged construction, precise tolerances, and broad accessory compatibility, backed by a trusted brand with extensive technical support and a robust parts ecosystem for long-term reliability.

How to install Middle Atlantic R4CN-5124B

• Plan your layout: Assess the available space, ensure clear front and rear access, confirm ventilation, and map where each device will sit to optimize airflow and cable management.
• Prepare components: Unpack carefully, verify all mounting rails and hardware are present, and group devices by function (power, network, compute) to simplify installation sequencing.
• Position the rack: Place the open-frame rack in the designated area, level it, and secure it if required by location or code to prevent movement during equipment installation.
• Attach mounting rails and mount devices: Install standard 19-inch mounting rails according to the included hardware, then begin mounting heavier devices first to maintain balance. Use appropriate screws and spacers to ensure secure mounting without interfering with doorways or back panels (if applicable).
• Route and organize cables: Plan cable paths using available cable management accessories, route power and data cables neatly, and label cables for future maintenance. Maintain ample clearance for cooling airflow and service access.
• Power up and verify: Connect power distribution units and essential devices, power on equipment, and monitor for proper cooling and connectivity. Make any necessary adjustments to cable routing or device placement to optimize airflow and ease of service.
