APC by Schneider Electric AR3157X617 48U NetShelter SX Open Frame Rack Enclosure
Overview
The APC by Schneider Electric AR3157X617 is a 48U open-frame server rack enclosure in the NetShelter SX family — delivered without side panels or doors. That distinction matters: if you're designing a high-density compute row where airflow management is handled at the row or room level (hot-aisle/cold-aisle containment, in-row cooling, or raised-floor plenum), removing the doors and sides from the equation eliminates the single biggest impediment to unrestricted front-to-back airflow. The result is a rack frame purpose-matched to data center floors, NOC builds, and open-lab environments where cooling architecture does the heavy lifting.
Standing 88.90 inches (225.8 cm) tall and finished in black, the AR3157X617 provides 48 rack units of usable vertical space — enough to densely populate a full compute and switching stack without splitting workloads across multiple enclosures. At 236.29 lb (107.18 kg) unloaded, this is a substantial steel structure; plan your floor load ratings before deployment, and confirm your raised-floor tile or poured-slab capacity with your facilities team before rolling it into position.
Key Features
- 48U Vertical Capacity: Forty-eight rack units in a single enclosure means a fully populated 1U switch stack, a mix of 2U servers, and a patch panel section can all coexist without overflow. For a 20-node compute cluster that grows incrementally, 48U gives you room to expand without a forklift swap.
- No Sides, No Doors — Airflow-First Design: Removing panels isn't just about saving weight — it eliminates the pressure drop created by enclosed cabinets in high-CFM environments. If your cooling system is designed to move air across the row rather than through individual cabinets, an open frame like the AR3157X617 is the correct architectural match. Enclosed cabinets in this scenario actually fight your cooling system.
- 88.90 in (225.8 cm) Installed Height: This enclosure reaches standard data center ceiling clearance thresholds. Verify your facility's raised-floor-to-ceiling measurement before ordering — some older co-lo suites with 9-foot ceilings have tight margins once you account for overhead cable trays and bus ducts.
- 236.29 lb (107.18 kg) Unloaded Weight: The frame itself weighs over 236 lb before a single server goes in. Factor this into floor loading calculations — a fully populated rack in a dense NVR or server deployment can easily reach 1,500–2,000+ lb total. This is not a rack for lightweight network closets.
- Black Finish: Standard data center black finish integrates cleanly with hot-aisle containment curtain systems and matching NetShelter SX enclosed cabinets if your row mixes open and closed frames.
- NetShelter SX Family Compatibility: The SX line has broad compatibility with APC's rack PDU lineup, cable management accessories, and containment systems. Sourcing accessories within the same family avoids fitment guesswork on rail depths and mounting hole patterns.
Integration & Compatibility
The AR3157X617 is a passive structural component — it does not include power distribution, cable management, or active cooling. Plan these as separate line items. For a complete rack deployment, pair this enclosure with a UPS system sized to your compute load, a rack-mount PDU matched to your outlet configuration, and vertical or horizontal cable managers appropriate to your cabling density. The open-frame design also simplifies integration with overhead busway power systems common in modern hyperscale-influenced enterprise builds.
If your project calls for physical security of rack contents — access control, locking side panels, or a front/rear door with key or electronic lock — the AR3157X617 is explicitly not the right model. Step to an enclosed NetShelter SX variant that ships with doors and side panels. Conversely, if you're installing this in an access-controlled data center cage or locked suite where cabinet-level door security is redundant, the open frame saves cost and simplifies maintenance access.
For security operations centers deploying NVR appliances or high-density video storage servers, the open-frame configuration keeps cable runs visible and traceable — a practical advantage when troubleshooting under time pressure. Similarly, IT architects building out core switching layers in structured cabling environments benefit from the unrestricted front access for hot-swap operations.
Frequently Asked Questions
Q: Does the AR3157X617 include side panels and doors?
A: No. The AR3157X617 ships specifically without sides and doors. This is intentional — it's designed for environments where row-level or room-level cooling handles airflow and cabinet enclosure is not required. If you need an enclosed cabinet, select a different NetShelter SX model that includes doors and side panels.
Q: What is the rack unit capacity of the AR3157X617?
A: The AR3157X617 provides 48U of usable rack space, standing 88.90 inches (225.8 cm) tall.
Q: How much does the AR3157X617 weigh?
A: The enclosure itself weighs 236.29 lb (107.18 kg) unloaded. Shipping weight with packaging is 269.36 lb (122.18 kg). Verify your floor load rating before installation, especially in raised-floor environments.
Q: Is the AR3157X617 compatible with APC rack PDUs and accessories?
A: The AR3157X617 is part of the NetShelter SX family, which is designed to be compatible with APC's rack PDU and cable management accessory lines. Confirm specific accessory compatibility against APC's current NetShelter SX accessory catalog for your exact configuration.
Q: Can the AR3157X617 be used in a hot-aisle/cold-aisle containment setup?
A: Yes — the open-frame, no-doors/no-sides design makes it well-suited for containment-based cooling architectures where airflow is managed at the row or room level rather than within each cabinet. This is one of the primary use cases for this configuration.
Q: What are the shipping dimensions for the AR3157X617?
A: The packaged shipping dimensions are 94.49 in H × 47.99 in W × 35.24 in D (240 cm × 121.9 cm × 89.5 cm), with a packaged weight of 269.36 lb (122.18 kg). Confirm freight elevator and door clearance before scheduling delivery to upper-floor data centers.
The AR3157X617 is the spec I reach for when a customer's cooling architecture is already doing the work — specifically, when they're running in-row coolers or full hot-aisle containment and every enclosed cabinet in the row is fighting the pressure differential rather than working with it. At 88.90 inches tall and 48U of open vertical space, this frame gives you maximum density without the airflow compromise of a fully baffled enclosure.
Technical Highlights:
- 48U Open Frame: Forty-eight rack units with no door or panel resistance means front-to-back airflow follows your room design rather than fighting cabinet baffling — critical in high-density deployments where per-rack heat loads exceed 10kW.
- 236.29 lb Unloaded Frame Weight: This is a structural data point, not just a shipping spec. At 236 lb bare, a fully loaded compute rack here can push floor loads well past 150 lb/sq ft — the threshold where many raised-floor systems require additional support columns or bracing.
- Shipping Package: 94.49 in H × 47.99 in W × 35.24 in D: The packaged height of 94.49 inches is taller than a standard 8-foot doorway. Freight routing through building corridors and elevator cab height clearance must be confirmed before delivery is scheduled — this is a common and expensive site-prep oversight on first-time data center builds.
Deployment Considerations:
- Because this model ships without sides and doors, it provides no physical access barrier at the cabinet level. Deploy it only in access-controlled data center spaces — locked cages, card-access suites, or secured NOC floors — where perimeter security compensates for the open frame.
- The 269.36 lb shipping weight means liftgate service and pallet jack access are non-negotiable on delivery day. Standard dock-high delivery without equipment is a damage and injury risk with this product.
The AR3157X617 belongs in enterprise data center rows running hot-aisle containment, not in network closets or branch-office IDF rooms. If you're building a structured cabling rack in a non-contained environment and need door locks for compliance, this is the wrong model — select an enclosed SX variant. But for a properly cooled, access-controlled data hall where you need 48U of density and zero airflow penalty, this is the correctly specified frame.
