Keep critical infrastructure organized, protected, and serviceable in a rack built for serious density. APC NetShelter SX AR3300X717 provides a 42U footprint with a 600 mm width and 1,200 mm depth, giving IT teams the space needed for deeper servers, switches, and power distribution hardware without crowding the enclosure. Side panels help maintain physical security and preserve a controlled internal environment, while the enclosure format supports cleaner cable routing and more predictable airflow than open-frame alternatives. That matters when uptime depends on stable thermal behavior, easier access during maintenance, and a layout that scales with changing hardware demands. This enclosure is a strong fit for data closets, edge deployments, and enterprise rack rooms where equipment density, protection, and service access all matter. It is designed for teams that want a rack enclosure with enough depth for modern infrastructure and enough structure to support long-term deployment discipline.
