APC NetShelter SX, Server Rack Enclosure, 45U, Black, 2124H x 750W x 1200D mm

The APC AR3355 is a 45U server rack enclosure that helps organize and protect critical IT hardware in data centers, server rooms, and network closets. It offers a frame that measures 750 mm wide and 1200 mm deep, giving ample room for high-density servers, switches, and storage appliances while still fitting within standard floor layouts.

APC designed this enclosure for environments where every inch matters. The split rear doors need just 11 inches of aisle space to swing open, so the cabinet can sit close to walls or neighboring racks without blocking service access. Pre-installed casters let you roll the rack into position, and integrated leveling feet lock it firmly in place once it is aligned with other enclosures.

Cable management and power distribution are simple thanks to rear accessory channels that accept PDUs and cable organizers without tools. Because these accessories mount outside of the standard rack-mounting rails, they preserve valuable U space for equipment and keep cables neatly routed for easier airflow and maintenance.

A frame made from high-strength steel supports static loads up to 3750 pounds, giving confidence when the rack is fully populated with heavy enterprise equipment. Compliance with UL and EIA-310E standards ensures broad compatibility with industry rack-mount devices and meets common safety requirements.

The AR3355 is well suited for enterprises upgrading to blade servers, managed switches, or converged infrastructure; co-location facilities that need robust, easily bayed cabinets; and any organization that wants a dependable enclosure that simplifies installation and day-to-day management.
