From the moment you unbox it, you’ll notice the attention to detail that APC brings to NetShelter SX enclosures. The AR3307X674 is optimized for high-density deployments, enabling you to spread a larger number of devices across fewer cabinets and reduce the footprint of your IT footprint. Its modular, tool-free design means you can adapt quickly to changing equipment needs—add or reconfigure rails, door options, or cable management accessories without downtime. If your environment requires precise routing of cables to ensure airflow and serviceability, this rack cabinet delivers with thoughtful cable access, secure mounting, and scalable features that fit a wide range of server, storage, and networking gear. In short, it’s a high-capacity, future-ready enclosure that helps data centers improve efficiency, organization, and resilience.

• Maximized U-space for high-density deployments: Designed to exceed the standard 48U height, this cabinet helps you maximize every rack space, enabling higher equipment density without expanding your floor footprint. By offering more U-per-rack space, it simplifies equipment organization, reduces cable clutter, and supports scalable growth as your infrastructure expands. This makes it an ideal choice for data centers, server rooms, and enterprise IT environments that demand compact, efficient, and accessible enclosures for a growing fleet of devices, storage arrays, and network gear.
• Cable Access Roof for streamlined cabling and PDU routing: CABLE ACCESS ROOF features five access holes with brush strips for cable passthrough, three without for PDU cable routing, and two spring-loaded pins that allow for easy roof removal. This design delivers fast, organized cabling without compromising cabinet rigidity. With dedicated paths for power distribution and data cabling, technicians can route cables cleanly, minimize tangles, and maintain optimal airflow through the cabinet to support cooler, more efficient operation of attached equipment.
• Rugged construction with security you can rely on: Constructed from heavy-duty steel with a durable powder-coated finish, NetShelter SX AR3307X674 is built to withstand the rigors of busy data centers. Lockable front and rear doors (plus removable side panels in many configurations) provide flexible security options and controlled access to sensitive equipment. The reinforced frame and precision-engineered joints ensure structural integrity under load, while modular components enable quick swaps or upgrades as your IT landscape evolves. This cabinet is designed to preserve equipment reliability and protect valuable assets in demanding environments.
• Advanced cable management and airflow optimization: In addition to roof access, the cabinet incorporates integrated vertical cable channels and rear cable troughs, helping you organize power and data lines without obstructing airflow. Perforated doors and optional panel configurations support efficient cooling by enabling even air distribution around densely packed devices. Clear, logical cable routing paths reduce maintenance time during upgrades and replacements, while keeping hot air from recirculating into equipment intakes—contributing to lower operating temperatures and extended hardware lifespans.
• Modulary, versatile, and easy to install: The NetShelter SX is designed for straightforward installation and ongoing flexibility. With adjustable 19-inch mounting rails, adaptable door configurations, and compatibility with a wide range of APC accessories, you can tailor the cabinet to your precise rack needs—and reconfigure as requirements change. Its scalable design accommodates additions like additional PDUs, cable management arms, cooling options, locking kits, and side panels, enabling a future-proof solution that grows with your data center without requiring a full cabinet replacement.

How to install APC by Schneider Electric NetShelter SX AR3307X674 Rack Cabinet

• Step 1: Plan your layout. Assess the room, power requirements, ventilation, and cable routing paths. Confirm floor space and clearance for door operation, access to the roof, and maintenance access to rear panels.
• Step 2: Prepare mounting rails. Install the adjustable 19-inch rails inside the cabinet according to your equipment depth and U count. Ensure rails are level and securely fastened to the cabinet frame to prevent shifting during device installation.
• Step 3: Assemble doors and panels. Mount the front and rear doors, plus removable side panels if included in your configuration. Check that hinges operate smoothly and that locking mechanisms engage securely to protect protected equipment.
• Step 4: Route cables with care. Use the five roof access points (brush-stripped) for pass-through cables and route PDU cables through the designated paths to minimize clutter and maximize airflow. Route data cables through vertical channels and maintain clear separation from power lines where possible to reduce interference and improve serviceability.
• Step 5: Install equipment. Slide servers, storage controllers, and network devices into the rails, secure them with cage nuts and screws, and connect power and data cables. Close the doors, verify door alignment, check cable relief and strain relief, and perform a basic functional test to confirm connectivity and airflow before placing the cabinet into full operation.
• Step 6: Validate airflow and accessibility. Confirm that air can flow unimpeded through perforated doors or panels and that maintenance access remains unobstructed. If needed, adjust cable routing or add additional accessories to optimize cooling and serviceability for your specific equipment mix.
