APC NetShelter SX AR7157 48U 750 mm Wide Black | Rack Enclosure

Build out dense infrastructure with a rack enclosure designed for serious equipment loads and practical day-to-day access. The NetShelter SX 48U format gives IT teams a full-height cabinet for servers, switching, storage, and supporting power gear, while the 750 mm width helps preserve a manageable footprint in standard data center rows. Perforated split doors are a meaningful detail. They support front-to-back airflow while making it easier to access sections of the rack without opening a single large door. That matters in live environments where thermal control, maintenance speed, and cable discipline all affect uptime. The black finish keeps the enclosure visually consistent with enterprise rack rows and helps it blend into professional installations. This is the kind of enclosure chosen when the rack itself is part of the infrastructure strategy, not just a place to put equipment. It is built for teams that want cleaner airflow paths, better service access, and a cabinet format that scales with demanding deployments.
