The APC AR3157SP is a 48U server rack enclosure from the NetShelter SX line, designed to house and protect networking, server, and power equipment in data center and equipment room environments. Standing 48 rack units tall with a 750mm width and 1070mm depth, this enclosure provides ample space for high-density server and networking gear. It is installed by qualified IT infrastructure technicians, data center electricians, and network engineers who require a rigid, organized mounting solution for critical equipment.
This enclosure is suited for data center builds, server room upgrades, and edge computing deployments where organized cable management and secure equipment housing are priorities. The 48U height accommodates a full rack of servers, patch panels, switches, and power distribution units. The 1070mm depth supports extended chassis and high-density server configurations common in enterprise environments.
Designed as an OEM-style enclosure for use with standard 19-inch rack-mount equipment. No specific compatible model numbers or system families were provided in the product data.
Installation should be performed by qualified IT infrastructure technicians or licensed electricians familiar with data center equipment practices. Power down and de-energize any adjacent active equipment before positioning the enclosure to avoid accidental contact with live circuits. Ensure the floor or mounting surface meets the load-bearing requirements for a fully populated 48U rack before securing the unit. Follow applicable local building and electrical codes, including NFPA 75 and NFPA 76 where data center fire protection standards apply.
