APC by Schneider Electric AR3150B2X609 42U NetShelter SX Gen 2 Server Rack Enclosure
Overview
The APC by Schneider Electric AR3150B2X609 is a 42U NetShelter SX Generation 2 open-frame rack enclosure built for high-density server, networking, and storage deployments in data centers and machine rooms. Standing 1,991mm tall with a 750mm width and a maximum usable depth of 1,070mm, this enclosure accommodates deep 2-post and 4-post equipment that won't fit in shallower alternatives. The 'without sides' configuration is a deliberate deployment choice — not a missing component — making the AR3150B2X609 the right pick when you're baying multiple racks together in a row or need unrestricted lateral airflow in an open-aisle architecture. Baying hardware is included in the box, so adjacent rack integration is ready out of the gate.
Key Features
- 42U Height (1,991mm): A full-height 42U rack gives you the vertical real estate to consolidate compute, switching, and patch in a single enclosure rather than splitting across two shorter racks — fewer enclosures to cable, fewer footprint SKUs to manage.
- 1,070mm Maximum Usable Depth: Deep-chassis 1U and 2U servers — many current-generation platforms run 900mm+ body depth before cabling — install without rear-rail compromise. The minimum mounting depth of 286mm means lightweight 1U switches and patch panels also mount properly at the front without rattling.
- 1,814.4kg Static / 1,020.6kg Dynamic Load Rating: The static figure is nearly two metric tons. A fully populated 42U rack of dense 2U servers rarely exceeds 1,000kg — this enclosure won't be your weight ceiling. The dynamic rating (1,020.6kg) matters for seismic zones or raised-floor environments where floor flex and vibration are factors.
- 14-Gauge EIA Mounting Rails: Heavier gauge on the rails means threads hold torque under repeated hardware swaps — relevant in colocation environments where customer equipment is racked, swapped, and re-racked on a rolling basis. Rail integrity is where cheaper enclosures show wear first.
- 19-Inch EIA Rail Standard: All standard 1U/2U/4U rackmount equipment — servers, switches, UPS units, KVM drawers — mounts directly without adapter rails.
- Side-Panel-Free Design for Bayed Rows: When you're building a row of four to ten racks, removing sides between adjacent enclosures eliminates the double-wall gap that forces cable routing around panels. Baying hardware is included, so the row ties together structurally without a separate accessory order.
- UL 2416 Listed: UL 2416 is the North American standard for IT rack enclosures covering structural integrity and safety. Listing means the enclosure has passed independent third-party testing — relevant for data center operators whose facility insurance or customer compliance programs require listed enclosures.
- 16-Gauge Front Door / 18-Gauge Rear Door and Roof: Graded gauge selection — heavier on the front where door-swing stress concentrates, lighter on the rear and roof where weight reduction matters more than repeated-handling wear. This is an engineering tradeoff, not a cost-cut.
Integration and Compatibility
The AR3150B2X609 is part of the NetShelter SX Enclosures range, which uses a standardized baying system. Baying hardware supplied with this unit allows side-by-side coupling with adjacent NetShelter SX racks. The 19-inch EIA rail system ensures compatibility with all standard rackmount equipment. For deployments requiring sides, blanking panels, or additional cable management, those components are available separately within the NetShelter SX accessory ecosystem. The without-sides configuration is specifically designed for multi-rack row deployments in open-aisle or hot-aisle/cold-aisle data center layouts where airflow and lateral cable access take priority over individual enclosure isolation. Power distribution within the rack is separate — pair with an appropriate rack PDU sized to your load. For large-scale physical infrastructure planning, review a data center rack selection guide to match enclosure depth and load rating to your specific platform mix before committing to a row configuration.
Frequently Asked Questions
Q: Why does the AR3150B2X609 ship without side panels — is something missing?
A: No. The 'without sides' designation is intentional. This configuration is engineered for bayed multi-rack row deployments where adjacent enclosures share a wall. Side panels between racks in a row create airflow dead zones and complicate lateral cable routing. Baying hardware is included with this unit to structurally connect adjacent NetShelter SX racks.
Q: What is the maximum equipment depth this rack can accommodate?
A: The AR3150B2X609 supports a maximum mounting depth of 914.9mm and a maximum internal depth of 1,070mm. Current-generation deep-chassis servers (typically 900mm+ body depth) install without rear-rail compromise. The minimum mounting depth is 286mm for shallow front-mounted equipment like patch panels and lightweight switches.
Q: What is the load capacity of the AR3150B2X609?
A: The static load rating is 1,814.4kg — sufficient for a fully populated 42U rack of dense servers. The dynamic load rating is 1,020.6kg, which applies in seismic or raised-floor environments where the enclosure may experience vibration or movement.
Q: Is the AR3150B2X609 UL listed?
A: Yes. This enclosure is listed to UL 2416, the North American standard for IT rack enclosures covering structural integrity and safety requirements.
Q: What baying hardware is included, and how many racks can be coupled?
A: Baying hardware is included in the package. This unit is part of the NetShelter SX Enclosures range, which uses a standardized baying system. Consult APC's NetShelter SX row configuration documentation for maximum continuous bay counts, which depend on facility floor loading and seismic requirements.
Q: What gauge steel is used for the mounting rails?
A: The EIA mounting rails are 14 gauge — the structural backbone of the enclosure. The front door is 16 gauge, and the rear door and roof are 18 gauge. Rail gauge matters most in colocation or shared environments where hardware is installed and removed repeatedly over the enclosure's service life.
The AR3150B2X609 is purpose-built for one specific deployment pattern: multi-rack rows in a structured data center or machine room. The 1,814.4kg static load rating and 1,070mm internal depth are the specs I look at first — those two numbers tell you this enclosure was sized for high-density compute, not a small office closet. The side-panel-free build is a deliberate architectural choice, not a cost reduction, and it's the right call when you're baying four or more racks together in a hot-aisle/cold-aisle layout.
Technical Highlights:
- 1,814.4kg Static Load: Exceeds the populated weight of virtually any realistic 42U configuration — you will not approach this ceiling with standard 1U/2U server and networking gear.
- 914.9mm Max Mounting Depth: Accommodates the full body depth of current-generation rack servers before accounting for cabling clearance — rear cable management accessories can still be deployed without sacrificing equipment fit.
- UL 2416 Listing: Third-party structural and safety certification that satisfies most data center operator, colocation, and enterprise insurance compliance requirements without additional paperwork.
Deployment Considerations:
- Plan your rack PDU selection before the enclosure arrives — this unit ships without power distribution, and PDU bracket compatibility varies across NetShelter SX accessory generations.
- At 123.86kg unloaded (154.55kg packaged), this enclosure requires a loading dock, pallet jack, and at minimum two people for positioning — factor that into your installation schedule, especially in elevator-served floors with weight restrictions.
The AR3150B2X609 is the right enclosure for a structured row deployment in a purpose-built data center or colocation cage where depth, load capacity, and baying capability are non-negotiable — not a fit for single-rack closet installs where a lidded enclosure with sides provides better cable containment and dust management.
