APC by Schneider Electric AR315 42U NetShelter SX Rack Enclosure
Overview
The AR315 is a server rack enclosure from the APC by Schneider Electric NetShelter SX line — a commercial-grade open-frame cabinet built for structured IT and data center environments where equipment density, airflow management, and physical security all matter. At 42U of usable rack space and a verified weight rating of 135 kg, this enclosure is sized for mid-to-large deployments: think dense switching stacks, patch panel runs, UPS integration, or mixed compute and storage builds in a single cabinet footprint.
Note: Verify current dimensional specifications — width and depth — directly with APC or your procurement contact before finalizing rack room layouts, as configuration details should be confirmed against the current APC datasheet for the AR315.
Key Features
- 42U Rack Height: 42U accommodates a full stack of 1U switches, patch panels, servers, and power distribution units without running out of vertical space mid-deployment. This is the standard depth for enterprise closets and data center rows — not a half-rack compromise.
- 135 kg Load Rating: At 135 kg (approximately 298 lbs), the AR315 handles dense switching and compute builds without structural concern. Heavy power distribution and UPS equipment can be integrated without approaching the weight ceiling on most deployments.
- NetShelter SX Platform: The SX line is APC's commercial data center rack family, designed around cable management, front/rear door airflow, and compatibility with APC's own PDUs, blanking panels, and side panels — reducing the integration work when building out a standardized equipment room.
Integration & Compatibility
The AR315 is part of the network infrastructure ecosystem built around APC NetShelter accessories: PDUs, blanking panels, brush strip cable entries, and side panels are designed to fit the SX rail and mounting geometry. APC publishes accessory compatibility data by model — confirm rail depth and side-panel fit against your specific load plan before ordering ancillary components. For high-density or hot-aisle/cold-aisle deployments, pair with APC in-row cooling or containment accessories rated for the SX footprint.
Frequently Asked Questions
Q: What is the usable rack space in the AR315?
A: The AR315 provides 42U of usable rack space, sufficient for dense switching, patching, compute, and power distribution equipment in a single cabinet.
Q: What is the weight capacity of the AR315?
A: The AR315 has a verified weight rating of 135 kg (approximately 298 lbs), supporting heavy equipment builds including UPS units and dense switching stacks.
Q: Is the AR315 compatible with APC PDUs and accessories?
A: The AR315 belongs to the NetShelter SX platform, which is designed to accept APC SX-compatible PDUs, blanking panels, and cable management accessories. Confirm specific accessory compatibility with APC documentation before ordering.
Q: What deployment environments is the AR315 suited for?
A: The AR315 is suited for commercial IT closets, data center rows, and structured cabling environments where 42U of equipment capacity and a high weight rating are required. Operating temperature and humidity ranges should be confirmed against the current APC datasheet.
The AR315 lands in the NetShelter SX family at 42U — that 135 kg load rating is the number I look at first when a customer is stacking UPS hardware, high-density PoE switches, and patch fields into a single cabinet. It holds up without drama.
Technical Highlights:
- 42U Capacity: Full 42U gives you room to build a complete edge stack — core switch, access switches, patch panels, UPS, and PDUs — without splitting across two cabinets and doubling your inter-cabinet cabling complexity.
- 135 kg Weight Rating: This ceiling matters most in UPS-dense builds. A typical rack-mount UPS at 2U can weigh 30–40 kg alone; the 135 kg rating leaves margin for real-world mixed loads without requiring a reinforced floor pad on most commercial slab construction.
- NetShelter SX Platform: SX accessories — cable managers, blanking panels, brush entries, side panels — are designed to the same rail geometry, which cuts integration time when standardizing across multiple cabinets in a room build.
Deployment Considerations:
- Confirm width and depth dimensions against the current APC datasheet before finalizing room layouts — rack room grid planning requires precise footprint data that should be pulled from the manufacturer spec sheet, not third-party sources.
- The 135 kg rating is a structural ceiling, not a thermal ceiling — high-density builds will hit airflow limits before weight limits. Plan blanking panel placement and front/rear door perforation accordingly.
The AR315 is the right call for a commercial IT closet or data center row build where you need a standardized, accessory-compatible 42U enclosure with a weight rating that handles mixed UPS and switching loads without compromise.
