APC by Schneider Electric AR3350X610 NetShelter SX 42U Doorless Freestanding Rack Enclosure
The AR3350X610 is a 42U freestanding rack enclosure from APC's NetShelter SX line — a 750mm-wide, 1200mm-deep cabinet built for high-density IT, networking, and physical security equipment in data centers, server rooms, and enterprise wiring closets. The doorless configuration is a deliberate engineering choice: it eliminates front and rear door airflow restrictions, making this enclosure the right pick for deployments where equipment generates significant heat and active airflow management — row-based or in-row cooling, hot-aisle/cold-aisle containment — is the thermal strategy.
Overview
At 1991mm tall with 42U of usable rack space, the AR3350X610 accommodates full-height infrastructure builds — top-of-rack switching, patch panels, 1U/2U servers, NVRs, storage arrays, and UPS units — without running out of vertical real estate mid-deployment. The 1200mm depth is the key differentiator from shallower SX variants: it handles extended servers, deep-chassis equipment, and bundled cable runs without forcing awkward rear-panel bends that compromise signal integrity or airflow.
Key Features
- 42U Capacity: 42 rack units gives you room to build a full production environment — top-of-rack switching, patch, compute, storage, and UPS — in a single enclosure without hitting the ceiling. In mixed NVR/switch/storage builds common in enterprise physical security, you won't be forced to split equipment across two cabinets.
- 750mm Width: Standard 750mm width (accommodating 19
