APC by Schneider Electric AR3150SP2 42U 750mm x 1070mm Open Frame Server Enclosure
Overview
The AR3150SP2 is APC by Schneider Electric's NetShelter SX 42U rack enclosure sized at 750mm wide by 1070mm deep — a configuration built for high-density server, network, and surveillance infrastructure where equipment depth and load capacity are non-negotiable. At 42U of usable vertical space and a maximum mounting depth of 36.02 in (91.49 cm), this enclosure accommodates full-depth servers, deep UPS units, and NVR appliances that shorter-depth racks simply cannot house. If you're specifying a data closet, server room, or control room for a large physical security deployment, the AR3150SP2 is worth evaluating before you commit to a footprint.
The enclosure ships in black and is designed around a 19-inch rail standard (EIA-310E), which means compatibility with virtually every rackmount device on the market — from managed PoE switches to high-channel NVR platforms to patch panels. It is not itself rack-mountable; this is a floor-standing unit. Plan your floor space accordingly: the unit stands 78.39 in tall (199.1 cm) and the packaged shipment measures 83.39 in high by 45.98 in wide by 47.99 in deep, weighing 443 lb. Freight delivery and a clear path to final placement are prerequisites, not afterthoughts.
Key Features
- 42U Vertical Capacity: Forty-two rack units gives you room for a full security stack — multiple NVRs, a video management server, PoE switch banks, a patch panel tier, and a UPS — without splitting across two enclosures and doubling your cable management complexity.
- 3,000 lb Dynamic / 2,250 lb Static Load Rating: The 3,000 lb (1,360.8 kg) dynamic load rating and 2,250 lb (1,020.6 kg) permanent permissible load mean you can fully populate this rack with dense 2U/4U servers and multi-bay storage without approaching structural limits. This matters in surveillance environments where high-channel NVR appliances with multiple drive bays add up quickly.
- 1,070mm Depth (36.02 in Maximum Mounting Depth): Many competitive enclosures top out at 900mm usable depth. The AR3150SP2's 1,070mm exterior translates to 36.02 in of maximum mounting depth — enough for full-depth 1U servers and deep-chassis UPS units that would overhang or simply not fit in a shallower frame.
- 750mm Interior Width: The 750mm width (29.53 in exterior) provides adequate side clearance around 19-inch mounted equipment for airflow management and cable routing without requiring a wider footprint than a standard 600mm enclosure.
- EIA-310E / UL 60950 Compliance: Meeting EIA-310E means the rail geometry is standardized, so mounting hardware from third-party equipment fits without modification. UL 60950 certification matters in commercial and enterprise environments where inspectors or facility managers require listed enclosures.
- Adjustable Mounting Depth (10.31 in to 36.02 in): The minimum mounting depth of 10.31 in (26.19 cm) means shallow networking gear, patch panels, and 1U switches mount flush and stable — you're not fighting oversized rail spans on shallow equipment.
- 5-Year Manufacturer Warranty: APC backs the AR3150SP2 with a 5-year repair or replace warranty, which matters for infrastructure components that are expected to serve for a decade or more. Enclosures are often the last thing refreshed in a rack cycle.
Integration and Compatibility
The AR3150SP2 follows the 19-inch EIA-310E standard, which means it accepts rackmount equipment from every major vendor in the physical security ecosystem — APC by Schneider Electric UPS and PDU products, managed PoE network switches, NVR appliances, video management servers, and patch panel assemblies all mount without adapter hardware. When sizing this enclosure for a network video recorder installation, account for UPS depth: APC Smart-UPS and Symmetra units in the 5–10 kVA range commonly run 26–30 inches deep, and the 36.02 in maximum mounting depth here accommodates them cleanly. For high-density deployments, pair with a rack PDU mounted vertically in the side channel to preserve usable U-space. This enclosure is not pre-configured with blanking panels, cable managers, or shelves — plan those as line items when specifying the complete build.
Frequently Asked Questions
Q: What is the maximum equipment depth the AR3150SP2 can accommodate?
A: The AR3150SP2 supports a maximum mounting depth of 36.02 inches (91.49 cm) and a minimum of 10.31 inches (26.19 cm). The overall enclosure depth is 42.13 inches (107 cm), so full-depth 1U servers and deep UPS chassis fit without modification.
Q: What is the load capacity of the AR3150SP2?
A: The AR3150SP2 has a permanent (static) permissible load of 2,250 lb (1,020.6 kg) and a dynamic permissible load of 3,000 lb (1,360.8 kg). This is sufficient for fully populated high-density server and storage configurations.
Q: Is the AR3150SP2 compatible with standard 19-inch rackmount equipment?
A: Yes. The AR3150SP2 is built to the EIA-310E standard with a 19-inch rail width, which is the universal standard for rackmount servers, switches, NVRs, patch panels, and UPS units from all major vendors.
Q: What is the warranty on the AR3150SP2?
A: APC by Schneider Electric covers the AR3150SP2 with a 5-year repair or replace manufacturer warranty.
Q: Can the AR3150SP2 be rack-mounted inside another enclosure or on a wall?
A: No. The AR3150SP2 is a floor-standing, free-standing enclosure and is not designed to be rack-mounted inside another unit or wall-mounted. It requires a clear floor footprint of approximately 29.53 in wide by 42.13 in deep.
Q: What are the shipping dimensions and weight for the AR3150SP2?
A: The packaged shipment measures 83.39 in high × 45.98 in wide × 47.99 in deep and weighs 443.1 lb (200.99 kg). Freight delivery with liftgate service is strongly recommended — this is not a parcel shipment.
The AR3150SP2 is the rack I spec when depth is the deciding constraint. That 36.02-inch maximum mounting depth is the number that matters — most 600mm-deep enclosures max out around 28 inches of usable rail, which leaves you improvising with full-depth UPS units or oversized storage servers. The AR3150SP2 eliminates that problem at the specification stage.
Technical Highlights:
- 3,000 lb Dynamic Load: At 1,360.8 kg rated dynamic capacity, you can fully populate 42U with dense dual-PSU servers and not be anywhere near the structural limit — relevant when a surveillance stack includes multiple high-channel NVR appliances with 12-bay drive chassis.
- 42U x 750mm Wide Footprint: The 750mm width versus a standard 600mm frame gives you real side clearance — enough to run vertical cable managers on both sides without crushing airflow or cramping horizontal cable trays.
- EIA-310E / UL 60950 Certified: Both certifications matter in commercial installs. EIA-310E means every standard rackmount kit fits without shimming; UL 60950 satisfies facility management and insurance requirements that specify listed enclosures for data rooms.
Deployment Considerations:
- At 443 lb packaged and 83.39 in tall in the shipping box, arrange freight delivery with liftgate and a pallet jack rated for the load before this ships — building service elevators with 400 lb limits will stop this unit at the loading dock.
- The AR3150SP2 ships as an enclosure only — blanking panels, cable managers, side panels, and roof/bottom grommets are separate line items. Build those into the BOM before submitting the order or you'll have a gapped rack with airflow bypass on day one.
This enclosure is the right call for a centralized control room or server room build where the rack will house a mixed stack of full-depth video management servers, deep-chassis UPS units, and high-port-count PoE switches — environments where a shallower 900mm enclosure would force either equipment compromise or a second rack.
