APC Netshelter SX GEN 2 48U Server Rack Enclosure 600MM X 1200MM W Sides Black - AR3307B2

APC by Schneider Electric AR3307B2 48U NetShelter SX Gen 2 Server Rack Enclosure

Overview

The APC by Schneider Electric AR3307B2 is a 48U, 600mm wide by 1200mm deep server rack enclosure built for data centers, server rooms, and network equipment deployments where physical density and cable management discipline matter. At 225.8 cm tall and rated to carry 146.2 kg of equipment, this is a full-height, high-capacity cabinet designed for production environments — not a patch panel closet. The enclosure ships in black with side panels included, offering both physical security and a clean installation footprint on the data center floor.

The NetShelter SX line has long been the baseline cabinet choice for enterprise IT and physical security integrators deploying NVR stacks, network switches, and server infrastructure. The Gen 2 revision refines airflow management and cable routing over the original SX, making it a practical choice for high-density 1U and 2U equipment that generates significant heat. If you are sourcing rack infrastructure for a network video recorder deployment or consolidating access control servers and PoE switch stacks, the AR3307B2 gives you the vertical space and load capacity to do it in a single cabinet.

Key Features

• 48U of Usable Rack Space: 48 rack units in a single enclosure means you can fully populate a dense NVR-plus-switch-plus-patch-panel stack without stacking multiple shorter cabinets. At 225.8 cm installed height, plan for adequate ceiling clearance before ordering — this is a true full-height cabinet.
• 600mm Width, 1200mm Depth: The 600mm wide footprint fits the standard 19-inch equipment rail pattern with room for side cable channels. The 1200mm depth accommodates full-depth servers, high-density blade chassis, and 1200mm-depth APC UPS units without the rear-door cable pinch common in 900mm or 1000mm cabinets.
• 146.2 kg Static Load Capacity: That translates to roughly 322 lbs of installed equipment — enough for a fully populated switch stack, multiple rack-mount servers, a rack-mount UPS, and patch panels simultaneously. Know your equipment weight before you load the cabinet; exceeding static load is a structural and warranty issue.
• Side Panels Included: Sides ship with the enclosure, giving you a closed-cabinet installation out of the box. Closed sides matter for directed airflow in hot-aisle/cold-aisle row configurations — open-frame racks bleed conditioned air into the room rather than channeling it through the equipment.
• Standard 19-inch Rack Rail: Universal 19-inch EIA-310 rail pattern means compatibility with effectively all rack-mount enterprise networking, computing, and PoE switch hardware. No proprietary rail adapters required for standard 1U/2U equipment.
• Black Finish: Matches standard data center and server room aesthetics. Relevant if your facility has mixed-vendor cabinet rows where color consistency matters for asset management photography or compliance audits.
• Floor-Standing, Non-Rack-Mountable: The AR3307B2 is a floor-standing enclosure — it does not mount inside another rack. This is the primary cabinet, not a sub-enclosure. Confirm floor load ratings for your installation site; a fully loaded 146 kg cabinet plus the enclosure's own weight concentrates significant load on a small footprint.

Integration and Compatibility

The AR3307B2 accepts standard 19-inch rack-mount equipment across all major enterprise vendors. APC's NetShelter SX line is designed to accept compatible APC accessories including PDUs (power distribution units), blanking panels, cable management arms, and thermal containment components — these are ordered separately and are not included with the base enclosure. When planning a high-density video surveillance or access control rack, pair this enclosure with a rack-mount PDU sized to your total equipment load and a structured cabling infrastructure plan before the cabinet is populated. The 1200mm depth specifically supports APC's own rack-mount UPS models that require full depth, which is a practical consideration for sites that need on-cabinet battery backup. For security integrators deploying this alongside an APC power and cooling ecosystem, the SX Gen 2 form factor aligns with APC's InRow cooling and containment accessories.

Frequently Asked Questions

Q: What is the usable rack unit capacity of the AR3307B2?

A: The AR3307B2 provides 48U of rack space on a standard 19-inch EIA-310 rail pattern.

The AR3307B2 is the enclosure I recommend when integrators ask for a single-cabinet solution that won't become a bottleneck six months after go-live. The 1200mm depth is the spec that matters most here — a lot of 48U cabinets ship at 1000mm and then you're fighting rear cable management the moment you install a full-depth UPS or a deep rack-mount server alongside your NVR stack.

Technical Highlights:

• 146.2 kg Static Load: At 322 lbs capacity, you have headroom for a fully populated NVR, a managed PoE switch stack, a rack-mount UPS, and structured cabling without approaching the structural limit — most real-world security rack builds land between 80–120 kg loaded.
• 1200mm Depth: Accommodates full-depth rack-mount UPS units and deep servers without compromising rear cable routing — the single most common reason integrators regret buying a shallower cabinet after the fact.
• 48U Height at 225.8 cm: Full-height footprint maximizes density per square meter of data center floor. A single AR3307B2 can consolidate what would otherwise require two 24U or 25U mid-height cabinets, simplifying power feeds and cable runs.

Deployment Considerations:

• At 225.8 cm, verify ceiling clearance and door height before delivery — this cabinet will not pass through a standard 7-foot interior door frame upright. Plan the installation route before it arrives on site.
• The 146.2 kg load limit is for the equipment only; the enclosure itself adds to the floor point load. Confirm your raised-floor or concrete slab rating before positioning — especially relevant in older buildings or modular facilities.

This enclosure is the right call for a primary data center or server room rack consolidating NVR infrastructure, network switching, and UPS backup into a single managed footprint — particularly on sites where the 1200mm depth lets you run full-depth APC UPS hardware co-located with the compute and networking stack.
