APC by Schneider Electric AR3358W2 52U NetShelter SX Gen 2 Server Rack
Overview
The APC by Schneider Electric AR3358W2 is a 52U Gen 2 NetShelter SX server rack enclosure finished in white, designed for data center and server room deployments where organized cable management and standardized rack density are priorities. At 800mm wide and 1200mm deep, it accommodates high-density server, storage, and networking equipment that requires additional rear clearance — the 1200mm depth is the spec that separates this from shallower 1000mm variants and makes it the right call for blade chassis, high-port-count switches, and rear-cabled storage arrays.
Key Features
- 52U Rack Capacity: 52U gives you roughly 10% more usable space than a standard 42U frame — meaningful if you are consolidating equipment from multiple racks or staging a high-density rollout where every unit of vertical space has a dollar cost.
- 800mm Width: The 800mm footprint (vs. the more common 600mm) provides extra lateral clearance for cable routing, wide blanking panels, and side-mounted PDUs without encroaching on adjacent rack lanes. Confirm your raised floor tile and aisle widths accommodate this before ordering.
- 1200mm Depth: Full 1200mm internal depth handles deep 2-post and 4-post server chassis, rear-exhaust switches, and cable managers without forcing compromise on rear door closure. This is the dimension that most commonly drives rack selection in high-density compute rows.
- Integrated Cable Management: Factory-fitted cable management keeps power and data runs organized from day one — reduces airflow obstruction in the rear channel and simplifies future adds, moves, and changes without a full cable re-pull.
- Side Panels Included: Shipped with side panels, so the enclosure arrives ready for contained hot-aisle/cold-aisle deployments. Side panels are a meaningful detail if you are building chimney or containment configurations — removing them later to fit containment hardware is straightforward.
- White Finish: The white colorway (vs. standard black) is specified for environments where color-coding racks by function or zone is part of the facilities standard — common in broadcast, healthcare, and financial data centers with strict labeling conventions.
- RoHS Compliance: RoHS certification confirms the enclosure meets EU hazardous materials restrictions — required for deployments in EU-regulated facilities or for enterprise buyers with environmental procurement mandates.
Integration & Compatibility
The AR3358W2 follows standard 19-inch EIA-310 rack rail spacing, making it compatible with virtually all rackmount server, storage, networking, and AV equipment. The 800mm width and 1200mm depth dimensions align with the broader APC by Schneider Electric NetShelter SX ecosystem, so APC blanking panels, cable managers, PDUs, and cooling accessories designed for the SX line mount directly without modification. For deployments requiring in-row or overhead cooling, verify your server rack row layout against the enclosure footprint before finalizing floor planning. If you are sizing power distribution, pair this rack with an appropriately rated rack PDU rated for your planned load density across 52U. Buyers building out structured cabling infrastructure should also review compatible cable management accessories to complete the installation.
Frequently Asked Questions
Q: What is the rack unit capacity of the AR3358W2?
A: The AR3358W2 provides 52U of usable rack space, which is approximately 10% more than a standard 42U enclosure.
Q: What are the external dimensions of the AR3358W2?
A: Based on verified specifications, the AR3358W2 is 800mm wide and 1200mm deep. The product designation references a height of approximately 2436mm — confirm exact external dimensions against your facility ceiling clearance and raised floor tile layout before ordering.
Q: Does the AR3358W2 ship with side panels?
A: Yes. The AR3358W2 includes side panels as part of the standard configuration, making it ready for contained aisle deployments out of the box.
Q: Is the AR3358W2 RoHS compliant?
A: Yes. The AR3358W2 carries RoHS certification, confirming it meets EU restrictions on hazardous substances — relevant for EU-regulated facilities and enterprise buyers with environmental procurement requirements.
Q: Is the AR3358W2 compatible with standard 19-inch rackmount equipment?
A: Yes. The AR3358W2 uses standard 19-inch EIA-310 rail spacing, making it compatible with virtually all rackmount servers, switches, storage arrays, and patch panels from any manufacturer.
The spec that drives most AR3358W2 selections is the 1200mm depth — I see integrators underestimate rear clearance requirements regularly, and then deal with the consequences when a blade chassis or a high-density patch field won't let the rear door close. The AR3358W2 solves that before it becomes a problem on the floor.
Technical Highlights:
- 52U Height: At 52U, this frame gives you room to grow within a single enclosure footprint — valuable in raised-floor environments where expanding the row means a facilities project, not just a rack order.
- 800mm Width: The extra width over a 600mm frame pays off in cable-dense installs — you get real lateral space for vertical cable managers and side-mounted power strips without fighting for clearance on every add.
- RoHS Certification: For enterprise and government buyers, RoHS is a line item on the procurement checklist. Having it documented on the AR3358W2 avoids a compliance hold during facilities review.
Deployment Considerations:
- The 800mm wide footprint requires careful row planning — standard 600mm aisle assumptions won't apply. Measure your raised floor tile grid and confirm hot-aisle/cold-aisle lane widths accommodate the wider footprint before committing to a row layout.
- Side panels ship installed, which is convenient for standalone deployments but adds a step if you are integrating this into an active containment system — factor in the panel removal time if you're fitting containment hardware day one.
This enclosure is the right fit for high-density compute rows in enterprise data centers, co-location cages, or broadcast infrastructure builds where deep chassis and a larger cable management envelope are non-negotiable requirements.
