APC NetShelter SX AR3340W2 42U 750 x 1200 mm | Networking Rack

Create a more disciplined network rack with a 42U enclosure sized for high-density switching, routing, and patching. The APC NetShelter SX Networking Enclosure Gen2 offers a 750 mm width and 1,200 mm depth, giving infrastructure teams the physical space needed for deeper equipment and cleaner cable paths. Vertical cable managers are built into the configuration, which matters when a rack carries many patch cords, uplinks, and cross-connects. Instead of forcing cable bundles into the same space as active hardware, the enclosure helps separate routing from equipment placement. That improves serviceability, reduces visual clutter, and makes it easier to trace changes during moves, adds, and changes. The 42U format supports larger network builds without multiplying rack count, which can simplify floor planning and standardization across sites. For enterprise teams, that consistency is valuable: fewer rack variations, more predictable layouts, and easier documentation. APC’s NetShelter SX platform is a practical choice when the rack must support both physical organization and operational speed. This model is built for environments where cable discipline is not optional.
