APC by Schneider Electric AR3150X609 42U NetShelter SX Server Rack Enclosure
Overview
The APC NetShelter SX AR3150X609 is a 42U, 750mm-wide by 1070mm-deep open-frame enclosure built for dense data center and server room deployments. At a 3,000 lb static load rating and 279.1 lbs net weight, this is commercial-grade infrastructure — the kind you spec for equipment-heavy rows, not lightweight AV carts. The 1070mm depth accommodates deep dual-post servers, patch panels, and cable management in the same bay without forcing compromises on cable routing. If you manage network infrastructure at scale, this cabinet is sized for the job.
Key Features
- 42U Rack Height: 42U of usable mounting space supports a full server stack — compute, storage, switching, and patch panels — without stacking two shorter cabinets or leaving dead space in the row.
- 750mm Wide Footprint: The extra 50mm over a standard 600mm-wide rack gives you clearance for side-mounted cable managers and wider blade chassis without forcing a wider aisle. Standard 19" equipment mounts correctly via the EIA-310 rail spacing.
- 1070mm Depth: Mounting depth adjusts from 10.31" minimum to 36.02" maximum — deep enough to house full-depth 1U servers (typically 25–28") with room behind for cable tie-offs. Shallow gear like patch panels sits at the front; deep servers push toward the rear without dead-gap shimming.
- 3,000 lb Static / 2,250 lb Dynamic Load Rating: The 3,000 lb static rating means a fully loaded bay of dense storage or GPU compute won't flex the frame. The 2,250 lb dynamic rating matters if the cabinet is ever rolled across a raised floor or repositioned — the structure holds under transit load.
- 16-Gauge Steel Front, Rear, and Vertical Posts: 16-gauge on the front door, rear door, and all four vertical posts delivers structural rigidity where the load is transferred. The roof steps down to 18-gauge — acceptable for top cable entry panels and brush strips where deflection loads are minimal.
- Black Finish: Standard data center black matches APC PDU and accessory color families, keeping mixed deployments visually consistent — a minor point that matters in customer-facing MDFs and co-location suites.
- 78.4" x 29.53" x 42.13" Exterior Dimensions: Verify floor tile spacing before ordering. At nearly 30" wide, two side-by-side AR3150X609 cabinets in a standard 24"-tile grid will require careful row planning or a 36"-tile aisle.
Integration and Compatibility
The AR3150X609 accepts standard APC power distribution units, vertical cable managers, blanking panels, and roof cable entry kits via the NetShelter SX accessory family. The 19" EIA rail system is universal — any rack-mount equipment from 1U to 7U+ seats without adapter plates. For network switch deployments, the 1070mm depth means you can run horizontal cable managers front and rear simultaneously without losing usable rail space. Pair with a rack cooling or containment solution if deploying in a hot-aisle/cold-aisle row — the open-top design supports blanked top panels and chimney kits from the SX accessory line.
Frequently Asked Questions
Q: What is the usable mounting depth range of the AR3150X609?
A: The AR3150X609 supports a minimum mounting depth of 10.31 inches and a maximum of 36.02 inches, accommodating everything from shallow patch panels to full-depth 1U servers.
Q: Can the AR3150X609 support fully loaded high-density storage or GPU servers?
A: Yes. The static load rating is 3,000 lbs, and the dynamic load rating is 2,250 lbs. A fully loaded 42U bay of high-density storage or compute hardware stays well within both limits in normal operating conditions.
Q: Does the AR3150X609 include side panels?
A: No. The product name specifies "Without Sides" — side panels are not included. They can be ordered separately from the NetShelter SX accessory line if containment or airflow management requires them.
Q: What exterior dimensions should I plan for when placing the AR3150X609 in a data center row?
A: The exterior dimensions are 78.4 inches tall x 29.53 inches wide x 42.13 inches deep. Account for the 29.53-inch width when planning row spacing and tile alignment on raised floors.
Q: What gauge steel is used on the doors and vertical posts?
A: The front door, rear door, and vertical posts are all 16-gauge steel. The roof is 18-gauge.
The AR3150X609 is the cabinet I recommend when a project calls for a single bay that won't be revisited — the 3,000 lb static load rating and 16-gauge vertical posts mean you're not guessing whether the frame can handle a future equipment refresh that adds another 2U of dense storage. The 1070mm depth is the real differentiator here; most integrators underestimate how fast rear cable management disappears in a 900mm cabinet once you factor in patch cords and PDU depth.
Technical Highlights:
- 3,000 lb Static Load: Handles a fully populated 42U of blade servers, dense storage, or GPU compute without frame deflection — no shimming, no post reinforcement kits needed.
- 10.31"–36.02" Adjustable Rail Depth: The 25.71-inch adjustment range means you can mix shallow networking gear at the front and full-depth servers mid-bay in the same enclosure without reordering the rail kit.
- 16-Gauge Doors and Posts: Structural steel where the load transfers — vertical posts and both doors — with an 18-gauge roof that keeps weight reasonable without sacrificing rigidity on the load-bearing members.
Deployment Considerations:
- At 279.1 lbs net weight, plan your floor load calculation before finalizing row placement — a fully loaded cabinet in this class will exceed 1,500 lbs in many high-density configs.
- The "Without Sides" configuration is intentional for in-row cooling or containment systems, but if you're using this in an open room without a containment aisle, order side panels separately to control airflow bypass.
Best fit for high-density colocation bays, enterprise server rooms running mixed compute and storage, or security operations centers where NVR stacks, network gear, and UPS units all land in the same physical row.
