APC by Schneider Electric AR3100TAA 42U NetShelter SX Server Rack Enclosure
Overview
The AR3100TAA is APC by Schneider Electric's TAA-compliant variant of the NetShelter SX 42U enclosure — a 600mm-wide, 1070mm-deep open-frame rack built for data centers, network closets, and government IT environments where Buy American / FAR compliance is a procurement requirement. At 42U of usable rack space with a 19-inch rail standard and a maximum mounting depth of 36.02 inches (91.49 cm), this enclosure accommodates full-depth servers, storage arrays, and dense network switching gear without compromise. If your procurement cycle requires TAA documentation, the AR3100TAA ships with the paperwork — no workarounds needed.

Key Features
- 42U Rack Height (78.39 in / 199.1 cm): A full 42U of front-to-back mounting space gives you room to deploy dense compute, storage, and switching in a single footprint — no need to split workloads across two shorter enclosures to hit capacity. Plan your server rack enclosure layout accordingly.
- 3,750 lb Dynamic Load Capacity: The AR3100TAA is rated for 3,750 lb (1,701 kg) of dynamic (rolling/moving) load — meaning you can fully populate it with dense blade chassis or storage arrays and relocate the rack without unloading equipment first. Static rating sits at 2,250 lb (1,020 kg). Either way, this is a rack that won't flex under real-world data center gear.
- 600mm Width / 1070mm Depth (23.62 in × 42.13 in): The 600mm-wide footprint fits standard 19-inch rackmount equipment and leaves usable cable management space on the sides. The 1070mm depth — with mounting depth adjustable from 7.52 to 36.02 inches — handles everything from shallow patch panels to 1U/2U full-depth servers and deep UPS units without adapter rails.
- TAA Compliance: The AR3100TAA carries TAA (Trade Agreements Act) compliance, making it eligible for U.S. federal, state, and GSA Schedule procurements. If your project requires TAA-compliant infrastructure throughout the rack, start here and pair with TAA-certified PDUs, switches, and cabling from compatible product families.
- Standards: UL 2416, UL 60950-1, EIA-310E: UL 2416 covers the enclosure as an IT cabinet; UL 60950-1 addresses IT equipment safety; EIA-310E sets the 19-inch rack rail standard. In practice, this means your rackmount equipment — servers, switches, NVRs, KVM switches — will bolt in using standard cage nuts and rails without adapter kits.
- 5-Year Repair or Replace Warranty: APC backs the AR3100TAA with a 5-year repair-or-replace warranty — considerably longer than the 1–2 year standard on commodity enclosures. For a rack that will house revenue-generating infrastructure for a decade or more, the warranty period matters when budgeting lifecycle replacement costs.
- 275.78 lb Enclosure Weight (125.09 kg): The AR3100TAA is a heavy-gauge steel enclosure — 276 lb unloaded. Factor this into floor loading calculations and plan for adequate personnel or mechanical lift for installation. Raised-floor environments should confirm point-load ratings before placement.
- Carbon Footprint Documented (439 kg CO₂ eq): APC publishes the product carbon footprint at 439 kg CO₂ equivalent — useful for organizations tracking Scope 3 emissions or meeting green procurement requirements in government and enterprise contracts.
Integration & Compatibility
The AR3100TAA uses the standard EIA-310E 19-inch rail pattern, so any rackmount equipment — including network video recorders, managed PoE switches, and server hardware — mounts without modification. Adjustable mounting depth (7.52 to 36.02 inches) means you can mix shallow 1U networking gear with full-depth storage or compute nodes in the same enclosure. APC's NetShelter SX accessory ecosystem — including cable management arms, blanking panels, side panels, roof/floor grommets, and bolt-down kits — is designed to integrate directly with this frame. For power distribution, APC's own rack PDU lineup (metered, switched, and TAA-compliant variants) mounts to the vertical rails using the enclosure's toolless PDU brackets. This enclosure is also compatible with APC's InfraStruXure and EcoStruxure physical infrastructure management systems if environmental monitoring and remote power management are in scope for your deployment. See APC's rack PDU and power distribution options for compliant pairing.
Frequently Asked Questions
Q: Is the AR3100TAA TAA compliant for federal procurement?
A: Yes. The AR3100TAA carries TAA (Trade Agreements Act) compliance, making it eligible for U.S. federal agency and GSA Schedule procurements that require TAA-compliant infrastructure.
Q: What is the load capacity of the AR3100TAA?
A: The AR3100TAA is rated for a dynamic (rolling) load of 3,750 lb (1,701 kg) and a static load of 2,250 lb (1,020 kg). You can fully populate it with dense servers or storage and move the rack without unloading equipment.
Q: What is the warranty on the AR3100TAA?
A: APC backs the AR3100TAA with a 5-year repair-or-replace warranty.
Q: What is the maximum equipment mounting depth in the AR3100TAA?
A: The maximum mounting depth is 36.02 inches (91.49 cm), with a minimum of 7.52 inches (19.1 cm). This range accommodates shallow patch panels through full-depth servers and storage arrays.
Q: What rack unit height and rail standard does the AR3100TAA use?
A: The AR3100TAA provides 42U of rack space and uses the standard EIA-310E 19-inch rail pattern, so all standard rackmount equipment installs without adapter hardware.
Q: What safety and quality standards does the AR3100TAA meet?
A: The AR3100TAA is certified to UL 2416 (IT cabinet standard), UL 60950-1 (IT equipment safety), and EIA-310E (19-inch rack rail standard).
When I spec the AR3100TAA into a federal or enterprise project, the conversation usually starts with two things: TAA compliance and load capacity. The 3,750 lb dynamic rating on this enclosure is the spec that closes the conversation — that's enough headroom to fully populate 42U with blade chassis, NVR appliances, and dense switching gear, then roll the rack into position without staging an unload. That's a real time-saver in large deployments.
Technical Highlights:
- 3,750 lb Dynamic / 2,250 lb Static Load: Handles fully-populated deployments of compute, storage, and networking without structural compromise. The dynamic rating means you can relocate a loaded rack — critical during staged data center buildouts.
- 36.02-inch Maximum Mounting Depth: Accommodates the full range from 1U shallow patch panels to deep 2U/4U servers and large-format UPS units. The 7.52-inch minimum is useful when you need to front-mount display hardware or thin access control appliances on the same rail set.
- TAA Compliance + UL 2416 / EIA-310E: This combination satisfies the three most common government IT procurement gates simultaneously — trade compliance, safety certification, and rail standardization — in a single SKU rather than requiring substitutions mid-project.
Deployment Considerations:
- At 275.78 lb unloaded, the AR3100TAA requires a mechanical lift or a minimum two-person team for positioning — especially relevant for above-floor raised environments where tipping risk increases. Verify floor point-load ratings before placement in older facilities.
- The 600mm width is the narrower NetShelter SX variant — sufficient for 19-inch gear but tighter on side cable management than the 750mm model. Plan vertical cable managers and horizontal cable rings before populating the rack, not after.
The AR3100TAA is the right call for federal civilian and DoD IT infrastructure projects where TAA documentation is a hard procurement gate and the rack will carry mixed compute and surveillance NVR workloads long-term — the 5-year warranty and documented carbon footprint satisfy both lifecycle and sustainability compliance requirements in a single enclosure spec.
