APC NetShelter SX, Server Rack Enclosure, 12U, Black, 658H x 600W x 1070D mm

The APC AR3103 is a twelve-unit server rack enclosure that delivers full-size cabinet capability in a footprint that fits under a desk or into an equipment nook. With external dimensions of 658 mm in height, 600 mm in width, and 1070 mm in depth, it accepts standard 19-inch hardware while keeping floor space free for everyday work.

Although compact, the cabinet handles up to 600 lb whether it rests on its leveling feet or rolls on the pre-installed casters. A frame made of steel provides strength and security, and the front door with a lock, removable side panels, and ventilated roof work together to protect equipment and support steady airflow. Top openings simplify cable routing, and clearly marked rack units speed installation.

This enclosure suits branch offices, edge computing sites, retail stores, classrooms, and test labs that need quiet, organized equipment storage. Use it to consolidate switches and patch panels beside desks, stage deep servers in a small data closet, or build a mobile proof-of-concept environment. Compliance with EIA-310E, UL 2416, and UL 60950-1, along with the five-year APC repair-or-replace warranty, adds confidence to every deployment.
