Keep critical infrastructure organized, accessible, and physically secure in a rack built for sustained enterprise use. The APC NetShelter SX AR3355W delivers 45U of mounting space in a white floor-standing enclosure designed for servers, LAN switches, and PDUs. Its 3,000 lb static load capacity supports dense equipment populations without forcing compromises on layout or expansion planning. At 47.2 in deep and 83.6 in tall, this rack gives teams the room needed for modern hardware footprints while preserving a clean, serviceable footprint in the data center or wiring closet. The NetShelter SX line is known for practical deployment details, and this model is no exception: it is built to handle structured cable routing, predictable rack alignment, and the physical demands of long-term infrastructure ownership. For organizations standardizing on APC by Schneider Electric, AR3355W offers the kind of capacity and finish that justify its place in higher-value environments. It is a rack intended for serious equipment density, not temporary staging. When uptime, serviceability, and rack integrity matter, this enclosure provides the foundation teams can build on with confidence.
