APC NetShelter SX AR3357WX617 48U 750mm x 1200mm | Rack Enclosure

When rack density and equipment depth increase, the enclosure has to keep pace. This APC NetShelter SX model delivers 48U of mounting space in a 750 mm wide, 1,200 mm deep footprint, giving infrastructure teams the room needed for larger server and network builds without sacrificing structural discipline. The open configuration, without sides and without a door, is well suited to environments where access strategy is defined elsewhere in the room design. It supports faster physical reach to installed equipment and can simplify integration in controlled spaces where enclosure accessories are specified separately. The deeper chassis is especially useful for modern hardware that demands more rear clearance for cabling, power, and service access. For procurement teams, the value is in the precision of the configuration. This is not a generic rack shell; it is a purpose-built platform for deployments that already know their containment model and need a deeper, higher-capacity foundation. In enterprise environments, that kind of fit matters. It reduces compromise, supports cleaner planning, and helps the rack row perform as a long-term asset rather than a temporary frame.
