APC NetShelter SX, Server Rack Enclosure, 48U, Black, 2258H x 750W x 1200D mm

The APC AR3357 is a 48U NetShelter SX server rack enclosure that gives data center managers a reliable home for high-density equipment. It arrives ready to accept standard EIA-310 hardware, so servers, switches, and storage arrays from almost any vendor slide straight in without special adapters.

Inside the cabinet you find 2258 mm of vertical space, 750 mm of width for generous cable channels, and a 1200 mm depth that accepts even the longest chassis. Four adjustable mounting rails let you set the exact depth you need, while clearly numbered rack units speed up installation and future moves.

Airflow and access are handled with the same care. The front and rear doors use a perforated steel design that promotes front-to-back cooling, and each door can be reversed in minutes to match your hot-aisle or cold-aisle layout. Side panels release with a simple latch, letting technicians reach power strips and cables without removing equipment from the rails.

Power distribution units, vertical cable organizers, and blanking panels attach quickly to the built-in accessory channels, creating a tidy interior that maximizes airflow. The cabinet’s steel frame supports a 3000 lb static load and 2250 lb dynamic load, so it stays stable during transport on the included casters.

Use the AR3357 in enterprise data centers that run dense virtualization clusters, in colocation suites where every rack unit counts, or in edge computing sites that demand secure, high-capacity enclosures. Compliance with UL 60950 and RoHS standards, plus a five-year APC warranty, adds the reassurance facility managers expect from a critical infrastructure brand.
