APC NetShelter SX AR3100 42U 600 mm x 1,070 mm | Rack Enclosure

Build a cleaner foundation for high-density equipment with a rack enclosure designed for serious infrastructure work. The APC NetShelter SX AR3100 provides 42U of space in a 600 mm wide by 1,070 mm deep footprint, giving teams a practical enclosure for servers, network gear, and supporting power equipment. The included side panels help protect installed hardware while keeping the enclosure visually and physically contained in shared spaces. At this size, the enclosure is well suited to environments that need predictable rack layout, straightforward equipment access, and a form factor that fits standard enterprise deployment patterns. The black finish keeps the presentation professional in data rooms, network closets, and colocation footprints. For procurement teams, this model earns its place by offering the structural consistency expected from a premium rack platform. It is a better fit than lighter enclosures when the deployment needs more usable depth, more vertical capacity, and a chassis that can support long-term infrastructure planning rather than short-term convenience.
