APC by Schneider Electric Netshelter SX Colocation 2 X 20U 750MM Wide X 1200MM Deep - AR3200X774

APC by Schneider Electric AR3200X774 NetShelter SX Colocation 2x20U Rack Enclosure

Overview

The APC by Schneider Electric AR3200X774 is a freestanding colocation rack enclosure designed for high-density data center environments where two independent tenants or departments need physically separated 20U spaces within a single 750mm-wide, 1200mm-deep footprint. Rather than deploying two standalone racks and doubling your floor tile count, this unit consolidates 40U of total capacity into one cabinet — a practical answer for colocation facilities, multi-tenant server rooms, and enterprise IT zones that require cabinet-level separation without the real estate cost.

The enclosure ships in a standard 19-inch (48.3 cm) form factor, which means it accepts any industry-standard 19" rackmount hardware: servers, patch panels, PDUs, UPS units, and KVM switches install without adapter plates or custom mounting. The 750mm width and 1200mm depth accommodate deep 2U and 4U servers with full cable management room behind the equipment, and the 1200mm depth in particular is well-suited to modern high-density compute nodes that routinely exceed 900mm in chassis length.

Sides are included, which matters operationally: enclosed sides enforce airflow discipline by preventing hot/cold aisle bypass, and they provide the physical delineation a colocation agreement typically requires between tenant spaces. For security-conscious deployments, sides also restrict lateral access to cabling and equipment without requiring a full cage build-out.

Key Features

• Dual 20U colocation split (40U total): Two independent 20U zones in a single enclosure eliminate the need for two separate rack footprints. In a colocation facility billed per cabinet or per square foot, consolidating two tenants into one unit cuts real estate costs in half while maintaining clear physical separation — a meaningful budget line for facilities running dozens of cabinets.
• 1704 kg maximum weight capacity: At 1,704 kg (roughly 3,757 lbs), this enclosure is engineered for fully loaded high-density deployments. A typical 1U server weighs 10–20 kg; even filling 40U with dense compute hardware will not approach this structural limit under normal conditions. This rating matters when stacking heavy UPS battery modules or dense storage arrays where per-shelf loading can be significant.
• 750mm width: The 750mm width is the preferred choice when deploying side-by-side racks in airflow-managed hot/cold aisle arrangements, as it provides sufficient clearance for vertical cable managers, PDU mounting, and blanking panel access without encroaching on adjacent cabinets. Facilities standardized on 750mm rows can drop this unit into existing floor layouts without reconfiguring aisle widths.
• 1200mm depth: A 1,200mm internal depth accommodates next-generation server platforms, including dense GPU compute nodes and high-capacity storage arrays that standard 1,000mm-deep racks cannot fit. If your hardware roadmap includes 1U-2U servers from major OEMs with rear-mounted power supplies and deep cable routing, this depth removes a common bottleneck before it becomes a problem.
• Standard 19-inch (48.3 cm) rack width: Full compliance with the EIA-310 19-inch rack standard means universal hardware compatibility. Every rackmount product from every major vendor — networking, compute, storage, AV, and security — mounts directly. No conversion kits, no rail adapters required in typical deployments.
• Freestanding form factor with included sides: As a freestanding enclosure with sides, the AR3200X774 functions as a self-contained unit from day one. Sides provide airflow containment (reducing hot air recirculation into cold aisles), physical security between tenant zones, and the structural rigidity needed when rolling the loaded cabinet across raised flooring during installation or reposition.
• Black finish: The standard black finish aligns with common data center aesthetics and reduces visible dust accumulation between cleaning cycles — a minor but real operational consideration in facilities where appearance standards are part of customer SLAs.

Integration and Compatibility

The AR3200X774 integrates directly into the broader APC by Schneider Electric NetShelter SX ecosystem. APC's rack PDUs, blanking panels, cable management accessories, roof fan trays, and side panels are designed to the same dimensional standard and mount without modification. This matters for facilities that want a consistent accessory and spare-parts inventory across their network cabinets and enclosures fleet.

For power distribution inside the enclosure, APC's vertical and horizontal rack PDUs mount to the rear vertical rails and feed equipment on both the upper and lower 20U sections independently — supporting per-tenant metering where required. Cable management arms, horizontal lacing bars, and D-ring hangers from the NetShelter accessory line fit directly without drilling or modification.

If you are planning a larger colocation build-out, pairing this enclosure with a structured data center infrastructure guide during the design phase helps validate floor loading, cooling approach (in-row vs. overhead), and power path redundancy before cabinets are placed on the floor.

The 19-inch EIA-310 rail standard means compute, networking, and UPS and power protection hardware from virtually any vendor installs without compatibility concerns. This is a passive enclosure — it has no powered components, no network management interface, and no firmware — so there are no software dependencies, driver requirements, or end-of-life software concerns to manage.

Frequently Asked Questions

Q: What is the total rack unit (U) capacity of the AR3200X774?

A: The AR3200X774 provides 40U of total usable rack space, split into two independent 20U sections to support colocation or departmental separation within a single enclosure.

Q: What is the maximum weight this enclosure can support?

A: The AR3200X774 is rated for a maximum static load of 1,704 kg (approximately 3,757 lbs), making it suitable for fully loaded high-density compute and storage configurations.

Q: Does the AR3200X774 ship with side panels?

A: Yes. Side panels are included with the AR3200X774, providing airflow containment, physical separation between the two colocation zones, and lateral access restriction without requiring a separate cage build-out.

Q: Is the AR3200X774 compatible with standard 19-inch rackmount equipment?

A: Yes. The enclosure conforms to the EIA-310 19-inch (48.3 cm) rack standard, so it accepts rackmount servers, switches, patch panels, PDUs, UPS units, and any other industry-standard 1U–4U hardware without adapter plates.

Q: What are the external dimensions of the AR3200X774?

A: The enclosure is 750mm wide and 1200mm deep. Height specifications should be confirmed against the manufacturer's current datasheet, as the total assembled height depends on optional top and base configuration.

Q: Can this enclosure be used in a hot/cold aisle containment layout?

A: Yes. The included sides and the 750mm width are well-suited to standard hot/cold aisle arrangements. The enclosed sides prevent inter-cabinet bypass airflow, which is a prerequisite for effective aisle containment.

Eden Phillips

The AR3200X774 is the unit I recommend when a colocation operator needs to maximize cabinet density without sacrificing tenant separation. That 1,704 kg structural rating gives you genuine headroom — I've seen facilities fully populate 40U with blade chassis and battery modules and still not approach the limit, which means you're not designing around a ceiling you'll hit in year two of a hardware refresh cycle.

Technical Highlights:

• 1,704 kg load capacity: Structural rating supports fully loaded high-density compute and storage in both 20U sections simultaneously — no derating for mixed hardware types.
• 1,200mm depth: Accommodates deep GPU compute nodes, high-density storage arrays, and rear-mounted cable bundles that standard 1,000mm enclosures cannot fit without forced cable routing compromises.
• Dual 20U split: Two physically separated zones in a single 750mm-wide footprint halves floor tile consumption vs. two standalone racks while preserving the tenant boundary that colocation SLAs require.

Deployment Considerations:

• The 750mm width fits standard hot/cold aisle spacing, but verify your floor tile grid before delivery — the 1,200mm depth means the cabinet extends further toward the aisle than a standard 1,000mm unit, which can affect blanking panel alignment on adjacent rows.
• This is a passive enclosure with no powered or managed components. Budget separately for PDUs, cable managers, blanking panels, and fan trays if your airflow and power distribution design requires them — none are included based on available product evidence.

This enclosure is the right call for a colocation build-out where two tenants need cabinet-level physical separation, dense hardware is in the roadmap, and floor space is priced by the square foot — the 40U-in-one-footprint consolidation is where it earns its place in the layout.
