APC NetShelter Rack PDU Enclosure AR3155 42U Deep Rack

The APC NetShelter SX AR3155 is a 42U deep-format open-frame rack enclosure engineered for high-density server, storage, and networking deployments. Built to the NetShelter SX standard, it features a 1200mm depth that provides generous cable management clearance behind rack-mounted equipment — a critical advantage when deploying power-dense compute nodes, GPU servers, and AI inference platforms that carry substantial rear-side cabling and power distribution infrastructure. The heavy-gauge steel frame supports a static load capacity of 1362 kg (3000 lbs), accommodating fully populated high-density configurations without structural compromise.

The AR3155 ships with a perforated front door and a split perforated rear door, both delivering high airflow efficiency to align with hot-aisle/cold-aisle containment strategies. The side panels are removable to support blanket containment systems or row-level cooling deployments. Adjustable mounting rails accommodate equipment depths common in enterprise server and storage hardware, and the integrated cable management features — including vertical cable managers and horizontal routing options — support structured cabling practices that reduce airflow obstruction and simplify maintenance access.

As a NetShelter SX variant, the AR3155 is fully compatible with the broader APC ecosystem including NetShelter containment accessories, APC rack PDUs, and blanking panels, making it straightforward to standardise infrastructure across multiple racks in a data centre row. Its 1200mm depth makes it particularly well-suited for modern AI and HPC workloads where dual-socket GPU servers, NVMe storage arrays, and high-port-count top-of-rack switches generate the rear-side complexity and thermal output that shallower enclosures cannot comfortably accommodate.

Ideal for

• AI and GPU compute deployments requiring extended rear clearance for multi-connector power cabling on dense accelerator servers
• High-performance computing (HPC) clusters where fully populated 2U and 4U dual-socket nodes demand maximum structural load capacity and airflow discipline
• Hyperconverged infrastructure (HCI) rows where deep storage nodes and integrated networking require structured rear cable management at scale
• Enterprise data centre standardisation programs adopting a single deep-format enclosure SKU compatible with APC containment and power distribution accessories
• Co-location deployments where operators must demonstrate structured cabling, containment-ready design, and high static load tolerance to meet facility requirements
• Top-of-rack switching and spine-leaf fabric buildouts where 100GbE or 400GbE switches carry large numbers of rear-side fibre and DAC cable bundles
