APC by Schneider Electric AR3100SP 42U 600mm Wide x 1070mm Deep Server Enclosure
Overview
The APC by Schneider Electric AR3100SP is a 42U, 600mm wide by 1070mm deep open-frame server enclosure built for high-density IT and physical security deployments where load capacity, cable management, and compliance matter. Standing 78.39 inches tall and rated for a static load of 3,750 lb, this is a server rack enclosure that handles dense NVR stacks, network gear, and UPS systems without flex or compromise. TAA and BAA compliance means it qualifies for federal procurement and government-facing integrations out of the box.
The AR3100SP ships as part of the broader APC by Schneider Electric infrastructure line, designed to pair directly with APC's PDUs, UPS units, airflow management accessories, and cable management rails — all engineered to the same NetShelter SX footprint and mounting standards.
Key Features
- 42U Capacity with 19-Inch Rail Width: Sixty-two inches of usable rack space at standard 19-inch rail width accommodates full-depth servers, NVR appliances, patch panels, and UPS hardware simultaneously. If you're consolidating a security head-end and IT gear into a single enclosure, 42U gives you room to grow without immediately planning a second cabinet.
- 3,750 lb Static / 2,250 lb Dynamic Load Rating: The static rating of 3,750 lb means this cabinet handles the weight of fully populated, high-density blade chassis or stacked NVR appliances without structural concern. The 2,250 lb dynamic rating — the load it can handle while being moved — is the number that matters during installation and relocation. Most competing enclosures at this width class rate dynamic loads significantly lower, making the AR3100SP the safer choice when you can't fully depopulate before moving.
- 1070mm Depth with 7.52–36.02 Inch Adjustable Mounting Depth: The adjustable mounting rail range (7.52 to 36.02 inches) accommodates everything from shallow patch panels to full-depth storage arrays. You're not buying a cabinet that forces you to use spacers or leaves half-depth equipment rattling on extended rails.
- 14-Gauge Mounting Rails: Heavier gauge than the 18-gauge used on the doors and side panels, the 14-gauge rails are where the load is actually carried. This is the correct design priority — the structural members are stout where it matters, without adding unnecessary weight to cosmetic panels.
- EIA-310E Compliance: Meets the standard rack unit dimensioning spec (EIA-310E) alongside UL 2416 and UL 60950-1 certification. This means any standard 19-inch rackmount equipment installs without shimming, custom brackets, or dimensional surprises.
- TAA and BAA Compliance: The AR3100SP satisfies both the Trade Agreements Act and Buy American Act requirements. For integrators working federal, state, or municipal contracts, this is a non-negotiable procurement gate — and having it verified at the enclosure level simplifies the compliance documentation stack.
- Color: Black with Consistent Gauge Differentiation: Front door at 16 gauge, side panels and roof at 18 gauge, rear door at 18 gauge. The front takes more physical contact in day-to-day operations, so the heavier front door gauge is a practical durability decision, not just a spec-sheet footnote.
- 5-Year Manufacturer Warranty (Repair or Replace): A five-year repair-or-replace commitment on a passive enclosure reflects confidence in build quality. For installations with 10-year depreciation schedules, this coverage window reduces the risk of structural replacement mid-lifecycle.
Integration and Compatibility
The AR3100SP is dimensioned to accept the full range of APC rack accessories including NetShelter SX blanking panels, toolless cable management rings, and side-mounting brackets for APC Smart-UPS and Symmetra units. The 600mm width footprint is the narrower of the two standard NetShelter SX widths (the other being 750mm), making it the right choice when floor space is constrained but you still need full 42U height. Pair it with an APC rack PDU and a compatible UPS to build a complete, standards-compliant power and protection stack. If your deployment involves high-density switching or NVR arrays generating significant heat, plan airflow management at design time — the AR3100SP's 1070mm depth supports front-to-back cooling paths, but blanking panels are required to prevent recirculation in mixed-height configurations.
Frequently Asked Questions
Q: Is the AR3100SP TAA and BAA compliant?
A: Yes. The AR3100SP carries both TAA (Trade Agreements Act) and BAA (Buy American Act) compliance, making it eligible for federal and government procurement contracts.
Q: What is the maximum static load rating for the AR3100SP?
A: The AR3100SP is rated for a static load of 3,750 lb (1,701 kg). The dynamic (rolling) load rating is 2,250 lb (1,020.6 kg).
Q: What is the adjustable mounting depth range on the AR3100SP?
A: The mounting rails adjust from a minimum depth of 7.52 inches (19.1 cm) to a maximum of 36.02 inches (91.49 cm), accommodating shallow patch panels through full-depth servers.
Q: What standards does the AR3100SP meet?
A: The AR3100SP is certified to UL 2416, UL 60950-1, and EIA-310E, covering structural, safety, and dimensional standards for data center enclosures.
Q: What is the warranty on the AR3100SP?
A: APC provides a 5-year repair-or-replace manufacturer warranty on the AR3100SP.
Q: Is the AR3100SP rack-mountable or floor-standing?
A: The AR3100SP is a floor-standing enclosure. It is not rack-mountable — it is itself the enclosure into which rackmount equipment is installed.
The AR3100SP is the enclosure I recommend when the load math actually matters. A 3,750 lb static rating sounds like overkill until you're stacking dual-PSU NVR appliances, PoE switches, a UPS, and a patch bay in the same 42U column — at that point, you're often closer to 1,500 lb than 500 lb, and the 2,250 lb dynamic rating is what lets you move the populated cabinet across a raised floor without partially depopulating it first.
Technical Highlights:
- 42U / 600mm Width: The narrower 600mm footprint (vs. the 750mm SX variant) recovers roughly 6 inches of floor depth per row in tight MDF/IDF closets without sacrificing rack unit count — meaningful in renovated spaces where floor plans weren't designed for modern enclosure depths.
- EIA-310E + UL 2416 Compliance: EIA-310E dimensional compliance means no surprises when installing third-party 19-inch equipment; UL 2416 covers the structural integrity of the enclosure itself under load. Both are verifiable on the label — not self-declared.
- TAA/BAA Compliance: For integrators carrying federal contracts, TAA/BAA at the enclosure level closes a documentation gap that's easy to miss at procurement. The AR3100SP has it verified — not just asserted.
Deployment Considerations:
- The 1070mm overall depth with a 36.02-inch maximum mounting depth supports full-depth equipment, but verify your deepest device's rail-to-rear clearance before spec'ing — some 1U appliances need 2–3 inches of rear cable egress beyond the rear rail.
- Package weight is 534 lb — plan for a liftgate delivery and two-person installation. The shipping carton dimensions (85.79 × 52.01 × 43.50 inches) also mean standard freight elevators are a potential bottleneck on upper-floor IDF installs.
This enclosure is the right call for physical security head-ends in government facilities, municipal command centers, or any deployment where TAA/BAA compliance is a contract requirement and the equipment load density is high enough that a lighter-duty cabinet creates structural or mobility risk.
