APC NetShelter SX, Server Rack Enclosure, 45U, White, 2124H x 600W x 1200D mm [TAA]

The APC NetShelter SX 45U server rack enclosure provides a premium, data‑center ready solution for housing IT gear with maximum security, scalability, and protection. Built to handle demanding workloads, this 45‑U cabinet combines rugged construction with thoughtful cable management, hot‑swappable access, and flexible mounting options. In a crisp white finish, it suits data rooms, edge deployments, and network closets where reliability and clean aesthetics are paramount. With generous interior space and a sturdy chassis, you can confidently house servers, storage arrays, and networking equipment while maintaining optimal airflow and ease of service.

• The enclosure features a robust 14‑gauge EIA mounting rail system paired with a 16‑gauge front door, plus 16‑gauge vertical posts and 18‑gauge rear door and side panels. This heavy‑duty construction supports high‑density rack gear and enduring operational use, providing a solid foundation for critical IT environments. The combination of thick rails and reinforced panels ensures rigidity, reduces flex under load, and helps maintain server stability during maintenance or vibration from dense equipment clusters.
• Designed for flexible configurations, the NetShelter SX ships with baying hardware and keyed‑alike doors and side panels, enabling seamless clustering of multiple enclosures for larger deployments. This modular approach simplifies capacity planning, reduces future downtime, and makes it easy to scale as your data center grows. Whether you’re consolidating blade servers or expanding storage arrays, you’ll appreciate the smooth alignment and secure connections that baying hardware provides.
• Mobility and leveling are built in to support diverse installation sites. The enclosure includes leveling feet for precise alignment on uneven floors and pre‑installed casters for easy repositioning during layout changes or maintenance windows. Once in place, you can lock the cabinet doors to protect equipment while maintaining the flexibility to move the enclosure when reconfiguring rack layouts or relocating hardware to optimize airflow and cable routes.
• Security and serviceability are at the forefront. The SX design emphasizes easy front and rear access for quick maintenance, with removable side panels and swing doors that reduce downtime during component swaps. The white powder‑coated finish not only looks professional but also resists chipping and corrosion in busy data rooms. The keyed‑alike doors and panels streamline access control, while the durable construction supports long‑term reliability even in demanding environments.
• Designed for compliance and durable performance, this model is listed as TAA‑compliant, making it suitable for U.S. government and other regulated procurement programs. The cabinet’s generous interior volume supports a wide range of equipment footprints, and its finish and construction are tuned for longevity, ease of cleaning, and consistent thermal management. By combining robust materials with practical design, APC NetShelter SX delivers a reliable home for critical IT gear while maintaining a professional data center appearance.

how to install APC NetShelter SX

• Prepare the installation site by ensuring a level, clean floor with adequate clearance for front, rear, and side access, as well as airflow paths around the cabinet.
• Unpack and inspect the enclosure for any shipping damage or missing components, including baying hardware, doors, and side panels. Verify that the 45U rails, casters, leveling feet, and fasteners are present.
• Install the casters or leveling feet according to the included guidance. If you anticipate frequent repositioning, attach the casters first and then level the cabinet after placing it into its final location.
• Mount the 14‑gauge EIA rails to the interior posts, aligning them to your preferred rack unit height. Use the provided mounting hardware to secure rails firmly, ensuring they are plumb and evenly spaced to support equipment weight.
• Route and organize cables using the built‑in cable management features and accessory managers. Leave enough slack at the rear of each rack tray to avoid kinking, and plan for future expansion with sufficient cable slack and proper bend radii.
• Install your servers, storage, and networking gear onto the rails, starting with heavier equipment at lower positions to lower center of gravity and simplify short‑term maintenance. Secure devices with cage nuts and screws, verify alignment, and test tray‑lock mechanisms.
• Attach the rear door and side panels for enclosure integrity, then install the front door. If you require clustering, connect baying hardware between adjacent enclosures and align doors for consistent access. Ensure keyed‑alike locks are engaged for security and convenience across units.
• Conduct a final check of door alignment, cable routing, airflow, and accessibility. Power up equipment in stages to monitor thermal performance and verify that fans and vents operate unobstructed for optimal cooling efficiency.
• Document the final configuration, including unit placements, cable paths, and security settings. Regular maintenance should include periodic inspections of rails, fasteners, and seals to preserve enclosure strength and reliability.
