APC Netshelter Soundproof 38U Server Rack Enclosure 120V Maple - AR4038LA

APC by Schneider Electric AR4038LA Soundproof 38U Server Rack Enclosure

Overview

The AR4038LA is a 38U freestanding soundproof server rack enclosure designed for deployments where acoustic control is a hard requirement — open-plan offices, operations centers, medical environments, and any space where server noise directly impacts the people working nearby. At 750 mm wide and 1130.4 mm deep, with mounting depths adjustable from 690 mm to 830 mm, the AR4038LA accommodates standard 19-inch (EIA-310D) equipment across a broad range of chassis sizes without forcing compromises on airflow or cable management.

The integrated 120V PDU and castor wheels mean this unit ships ready to roll into position and power up — no separate power distribution sourcing required on initial deployment. If you're evaluating APC by Schneider Electric rack solutions for a noise-sensitive environment, the AR4038LA is the specific model built for that constraint.

Key Features

• 38U Rack Capacity with EIA-310D Compliance: Thirty-eight usable rack units in a standard 19-inch (48.3 cm) wide form factor means you can load this enclosure with production servers, patch panels, KVM switches, and power distribution without worrying about non-standard equipment compatibility. EIA-310D certification confirms dimensional conformance — critical when mixing vendor equipment across a shared enclosure.
• Acoustic Soundproofing: The defining feature of this enclosure class. Soundproofing panels reduce radiated server noise into the surrounding space — relevant in any environment where IT equipment shares floorspace with staff. This is not a standard open-frame or vented rack; the AR4038LA is purpose-built for acoustic mitigation, which adds enclosure mass and requires careful attention to internal thermal management.
• 1500 kg Static Weight Capacity: A 1,500 kg static load rating means you can fully populate this 38U enclosure with dense compute — blade chassis, storage arrays, or UPS modules — without approaching structural limits. The rolling (dynamic) rating drops to 750 kg, so plan your configuration with that in mind when moving a loaded rack across a data floor.
• Adjustable Mounting Depth (690–830 mm): Equipment mounting rails adjust between 690 mm and 830 mm depth, accommodating everything from shallow patch panels to deep 1U servers and storage appliances. This range covers the majority of commercial enterprise and edge-compute hardware without rail extender kits.
• Integrated 120V PDU: A factory-installed PDU eliminates the need to source and mount a separate power strip on initial setup. The 120V / 50-60 Hz input aligns with standard North American single-phase circuits — confirm your facility breaker sizing against your planned load before commissioning.
• Castor Wheels for Repositioning: Castor wheels allow the enclosure to be rolled into position during installation and repositioned without full de-rack procedures. Factor in the 750 kg dynamic weight limit — a fully loaded rack at or near static capacity should not be moved on castors without partial unloading.
• Maple Finish: The AR4038LA ships in a Black and Maple colour combination — functionally identical to the standard black NetShelter variants but visually suited to executive briefing rooms, lobbies, or office environments where a polished appearance matters alongside noise reduction.
• 750 mm Width Chassis: Wider than the minimum 600 mm rack standard, the 750 mm external width provides additional internal volume for cable management arms, side-entry cabling, and acoustic panel thickness without compressing usable equipment depth.

Integration and Compatibility

The AR4038LA is a freestanding server rack enclosure that accepts any EIA-310D-compliant 19-inch equipment. It is not tied to a specific vendor's server line, network platform, or UPS ecosystem — rack-mount equipment from any manufacturer installs on the standard square-hole or threaded-rail system. The 120V input PDU is compatible with standard NEMA plugs used across North American commercial installations.

For environments requiring integrated power protection, pair this enclosure with a rack-mount UPS unit sized to your connected load — the 38U capacity leaves sufficient rack space for a 2U–4U UPS alongside compute and networking equipment. Cable management accessories and blanking panels from the standard rack accessory line are compatible with the 19-inch rail system.

The unit's depth of 1130.4 mm and 750 mm width requires a minimum floor footprint of approximately 0.85 m²; confirm raised-floor tile alignment and overhead cable tray routing before positioning. For facilities with weight-rated flooring, note the 1500 kg static capacity and plan load distribution across the castor footprint accordingly.

Frequently Asked Questions

Q: What is the usable rack space in the AR4038LA?

A: The AR4038LA provides 38U of usable rack space on a standard EIA-310D 19-inch (48.3 cm) rail system. Mounting depth is adjustable between 690 mm and 830 mm to accommodate equipment of varying chassis depth.

Q: What is the maximum weight this rack can hold?

A: The static load capacity is 1,500 kg. The rolling (dynamic) capacity when moving the rack on its castor wheels is 750 kg. For safety, partially unload the rack before repositioning if your configuration approaches the static limit.

Q: Does the AR4038LA include a power distribution unit?

A: Yes. The AR4038LA includes an integrated main PDU rated for 120V / 50–60 Hz input, which covers standard North American single-phase power. No separate PDU purchase is required for basic power distribution to rack-mounted equipment.

Q: What makes this enclosure soundproof — how does it compare to a standard vented rack?

A: The AR4038LA is purpose-built for acoustic noise reduction, using soundproofing panels integrated into the enclosure walls. Standard vented racks (such as the NetShelter SX line) prioritize airflow and do not include acoustic treatment. The tradeoff is that the AR4038LA requires more deliberate internal thermal management since the enclosure restricts passive airflow that open racks allow freely.

Q: Is the AR4038LA compatible with standard 19-inch rack equipment from any vendor?

A: Yes. EIA-310D certification confirms this enclosure meets the standard 19-inch rack dimension specification, so equipment from any manufacturer that follows that standard — servers, switches, patch panels, UPS units, KVM drawers — installs without modification.

Q: Can the AR4038LA be moved once installed?

A: The enclosure includes castor wheels for repositioning. The dynamic (rolling) weight limit is 750 kg, which is half the 1,500 kg static rating. If your loaded rack approaches or exceeds 750 kg, partially unload equipment before moving to stay within the rolling weight limit.

Karl Wilson

The AR4038LA occupies a specific niche that standard rack enclosures don't fill: 38U of EIA-310D-compliant capacity in an acoustically treated enclosure rated to 1,500 kg static load. I've specified this model for edge deployments in executive briefing centers and clinical environments where server noise is genuinely a design constraint — not a preference, but a hard requirement imposed by the space.

Technical Highlights:

• Dual Weight Ratings (1500 kg static / 750 kg rolling): The 2:1 ratio between static and rolling capacity is a real planning constraint. You can load this enclosure to near-full density, but the moment you need to reposition it, you're at half that limit. Plan your rack layout with staged unload access in mind if the enclosure will ever need to move post-commissioning.
• Adjustable Mounting Depth 690–830 mm: The 140 mm adjustment range handles the real-world spread of enterprise hardware — from shallow 1U switches to deep storage controllers — without rail extenders. This matters in a soundproof enclosure where adding aftermarket rail kits can compromise the acoustic seal at the front door.
• Integrated 120V / 50–60 Hz PDU: Having the PDU factory-installed removes one configuration variable from the deployment checklist. The 120V spec is specific — this is not a dual-voltage unit, so international deployments or facilities running 208V single-phase will need a separate power distribution approach.

Deployment Considerations:

• Soundproof enclosures trap heat more aggressively than vented racks. Validate your internal thermal load against the enclosure's airflow design before populating above 60–70% capacity with high-TDP equipment like dense blade servers or GPU compute nodes.
• The 1130.4 mm external depth requires careful floor-plan clearance: factor in front and rear door swing radius plus minimum service access clearance (typically 900 mm front, 600 mm rear) when placing the unit against walls or in corridors.

For a clinical environment, a security operations center, or an executive floor IDF closet where noise ordinances or occupant comfort drive the enclosure spec, the AR4038LA is the correct model. For a standard data hall or wiring closet where acoustic treatment adds cost with no return, a vented NetShelter SX at the same U count will serve better.
