APC NetShelter SX 42U Rack Enclosure 750mm Wide x 1200mm Deep

The APC NetShelter SX 42U 750mm Wide x 1200mm Deep Rack Enclosure (AR3350) is a professional-grade open-frame-style enclosed cabinet engineered for high-density server, storage, and networking deployments in enterprise data centers. The 750mm internal width accommodates standard 19-inch rack equipment while providing the additional lateral clearance required for high-cable-density environments, dense patch panel installations, and wide-body networking chassis. The 1200mm depth supports full-length 1U and 2U servers, deep storage arrays, and modern GPU-accelerated compute nodes without compromising airflow or cable management integrity.

The enclosure is constructed from heavy-gauge steel and features a perforated front door and a split perforated rear door, each delivering greater than 63% open area to promote front-to-rear airflow consistent with hot-aisle/cold-aisle containment strategies. Integrated vertical and horizontal cable managers, tool-less mounting rails with clearly marked rack unit positions, and a robust locking mechanism on all access panels are standard features. The adjustable mounting rails support both square-hole and round-hole configurations, and the cabinet ships fully assembled to reduce installation time in live data center environments.

With a static load capacity of 1360 kg (3000 lbs) and a dynamic (rolling) load rating of 1360 kg, the AR3350 is suitable for demanding AI cluster buildouts, high-density blade server installations, top-of-rack switching deployments, and colocation environments where structural integrity under full equipment load is a baseline requirement. The enclosure is compatible with the full APC NetShelter accessory ecosystem, including blanking panels, side panels, roof fan trays, and aisle containment components, enabling modular expansion as infrastructure requirements evolve.

Ideal for

• High-density AI and GPU cluster buildouts requiring extra lateral cable clearance and deep chassis accommodation for full-length accelerator cards
• Enterprise core switching and routing installations where wide-body chassis such as Cisco Catalyst 9500 or Arista 7800 series require the additional 750mm internal width
• Colocation data center deployments demanding structural load ratings suitable for fully populated blade server or storage array configurations
• Hot-aisle/cold-aisle containment environments where high-percentage perforated doors are mandatory to maintain CFD-validated airflow targets
• Dense patch panel and structured cabling installations in network operations centers where cable radius management across multiple 1U panels requires wider cabinet footprints
• Modular data center expansion projects leveraging APC's unified NetShelter accessory ecosystem for side panels, containment, and power distribution alignment
