APC by Schneider Electric AR9657SPB2 NetShelter SX Gen 2 48U High-Strength Freestanding Rack
The AR9657SPB2 is APC's NetShelter SX Gen 2 high-strength 48U freestanding rack enclosure — a 750mm-wide, 1470mm-deep cabinet built for dense IT and security infrastructure deployments where structural integrity, cable management, and equipment compatibility are non-negotiable. At 2256mm tall with 48 usable rack units, this enclosure gives you the vertical real estate to consolidate NVRs, network switches, access control servers, and PoE distribution gear in a single structured footprint.
Overview
The NetShelter SX Gen 2 line is APC's workhorse enclosure for enterprise data centers, security operations centers, and large-scale surveillance backrooms. The AR9657SPB2 specifically targets high-density installations: the 1470mm depth accommodates even the longest blade chassis and high-port-count switch configurations without forcing front-to-rear cable compression. The 750mm width aligns with standard aisle planning in raised-floor and slab data rooms alike. Explore the full APC by Schneider Electric catalog to pair this enclosure with compatible PDUs, UPS units, and cable management accessories.
Key Features
- 48U Capacity: 48 rack units of usable mounting space — enough to house a fully loaded NVR stack (10–12 units), top-of-rack switches, patch panels, and a UPS in a single enclosure without running out of vertical space mid-project. Planning a phased build-out? You'll have room to grow without buying a second cabinet.
- 750mm Width: The 750mm wide form factor (versus the standard 600mm) provides extra internal clearance for side-mounted cable management, power distribution units, and blanking infrastructure. If you're routing a high count of Cat6A or fiber trunks, that 150mm matters more than it sounds — it's the difference between a serviceable rear panel and a cable maze.
- 1470mm Depth — 29.2cm to 132.1cm Adjustable Mounting: With a mounting depth range of 29.2cm to 132.1cm, this cabinet handles everything from shallow 1U appliances to 1200mm-deep hyperconverged nodes. Integrators running a mixed hardware stack — say, Axis S3008 NVRs alongside full-depth Cisco Catalyst switches — can rack both without shimming or workaround brackets. See our network switches category for compatible top-of-rack options.
