APC Netshelter SX Server Rack GEN 2 52U 2436H X 750W X 1200D MM with Sides - AR3358B2

APC by Schneider Electric AR3358B2 52U NetShelter SX Gen 2 Server Rack Enclosure with Sides

Overview

The APC NetShelter SX Generation 2 AR3358B2 is a 52U rack enclosure built for dense server, networking, and storage deployments where physical depth and cable organization matter. At 800mm wide and 1200mm deep, it accommodates full-depth servers, dual power supplies, and the cabling infrastructure that goes with them — without forcing compromise on airflow path or rear-of-rack access. The white finish and included side panels make it a practical choice for environments where aesthetics factor into facilities approval, including branch offices, trading floors, and integrated operations centers.

With 52U of usable vertical space, this enclosure gives you room to consolidate computing, switching, patching, and power distribution in a single footprint — reducing the floor space required versus splitting across two mid-size racks.

Key Features

• 52U Vertical Capacity: Ten more rack units than a standard 42U frame means you can house a full server stack — compute, top-of-rack switching, patch panels, and a pair of PDU verticals — without running out of space mid-deployment. If you've ever had to overflow into a second rack because a 42U ran out at the worst moment, the extra headroom here is worth the planning.
• 800mm Cabinet Width: The 800mm width (wider than the 600mm standard) accommodates side-by-side vertical cable managers and wide-format networking gear without squeezing cable bend radii at the sides. Structured cabling runs stay organized, and vertical PDUs fit without blocking horizontal tray access.
• 1200mm Usable Depth: Full-depth servers — including high-density compute nodes with rear-facing GPU cards or dual-port SFP+ — fit without door interference. The 1200mm depth also leaves room for rear vertical cable management between equipment and the rear door, which matters when you're running structured fiber alongside power.
• Integrated Cable Management: Factory-included cable management provisions keep horizontal runs organized at the rack level from day one, reducing the rework cost of retrofitting cable managers after the fact. Clean cable paths also improve airflow predictability, which directly affects thermal performance across densely populated units.
• Included Side Panels: Shipped with side panels installed — relevant for open-floor or end-of-row placements where exposed side cabling or equipment is a security or aesthetics concern. Facilities teams and auditors will notice.
• 2436mm Overall Height: The 2436mm cabinet height (just under 8 feet) is designed to fit standard commercial ceiling clearances while maximizing usable U-space. Confirm your raised floor or slab-to-ceiling measurement before specifying — this is a tall cabinet.
• RoHS Compliance: RoHS-compliant construction satisfies procurement requirements for EU-bound deployments and green IT mandates common in government, healthcare, and financial sector purchasing contracts.
• White Finish: The white colorway is purpose-chosen for environments where rack rooms are visible to non-technical staff — broadcast facilities, trading desks, executive briefing centers, and colocation suites where aesthetics are part of the spec.

Integration & Compatibility

The AR3358B2 follows standard EIA-310-compliant rack unit spacing, making it compatible with rails, blanking panels, shelf kits, and PDUs designed for 19-inch rack mounting — including APC's own rack PDU lineup and third-party rail kits from major server vendors. The 1200mm depth is specifically sized to accommodate full-depth rail-mounted servers from Dell, HPE, Lenovo, and Supermicro without modification.

For power distribution and UPS infrastructure integration, the 800mm cabinet width supports both horizontal and vertical PDU mounting configurations. Pair with a rack enclosure accessories for blanking panels, toolless rails, and cable management arms to complete the build. If you are planning a structured network switching deployment within the same enclosure, the 52U capacity and 1200mm depth give you flexibility to run both compute and networking tiers in a single cabinet.

Consult the APC by Schneider Electric catalog for compatible accessories including cage nuts, PDU brackets, and airflow blanking kits designed for the NetShelter SX Generation 2 form factor. For larger multi-rack environments, the AR3358B2 can be joined with compatible aisle containment and overhead cable tray systems to form a contained hot-aisle or cold-aisle architecture.

Frequently Asked Questions

Q: What is the usable rack space in the AR3358B2?

A: The AR3358B2 provides 52U of usable vertical rack space, which is 10U more than a standard 42U enclosure. This accommodates dense server, networking, and power distribution configurations in a single cabinet footprint.

Q: What are the physical dimensions of the AR3358B2?

A: The AR3358B2 is 2436mm tall, 800mm wide, and 1200mm deep. Convert to inches: approximately 95.9 inches tall, 31.5 inches wide, and 47.2 inches deep. Verify ceiling clearance before installation.

Q: Does the AR3358B2 include side panels?

A: Yes. The AR3358B2 ships with side panels included, making it ready for open-floor, end-of-row, or facilities-visible deployments without additional panel purchases.

Q: Is the AR3358B2 RoHS compliant?

A: Yes. The AR3358B2 carries RoHS compliance certification, satisfying EU environmental directives and green IT procurement requirements common in government, healthcare, and financial sector purchasing.

Q: Will full-depth servers fit in the AR3358B2?

A: Yes. The 1200mm depth accommodates full-depth rail-mounted servers from major vendors including Dell, HPE, Lenovo, and Supermicro, with room remaining for rear cable management between equipment and the rear door.

Q: Is the AR3358B2 compatible with standard 19-inch rack equipment?

A: Yes. The AR3358B2 follows EIA-310-compliant 19-inch rack unit spacing, making it compatible with standard rail kits, PDUs, blanking panels, and shelf kits from APC and third-party vendors.

James Everett

The AR3358B2 earns its place in dense deployment planning primarily because of its 52U capacity combined with the 1200mm depth — a pairing that lets you spec full-depth compute, rear-facing structured cabling, and vertical PDUs into a single cabinet without the compromises you accept in a shallower or shorter enclosure.

Technical Highlights:

• 52U Capacity: Ten additional units above a standard 42U gives real flexibility for consolidating switching, patch, compute, and power in one frame — fewer cabinets means less inter-rack cabling and simpler airflow management.
• 800mm Width: The wider-than-standard footprint accommodates side-by-side vertical cable managers without sacrificing access to horizontal cable trays — the difference is noticeable once you're running structured fiber alongside power at scale.
• 1200mm Depth: Enough rear clearance for cable management between equipment tails and the rear door — a detail that matters on high-density builds where poor rear cable organization kills airflow and forces manual intervention during maintenance.

Deployment Considerations:

• At 2436mm tall, this cabinet is close to 8 feet — measure your ceiling clearance and any raised floor tile removal path before delivery. Data center build-outs with low-clearance cable trays overhead can make positioning difficult.
• The white finish, while purpose-built for aesthetics-sensitive environments, may show wear faster than standard black in high-touch facilities maintenance areas. Factor that into your site standards if longevity of appearance matters to facilities.

The AR3358B2 is the right specification for branch-office server rooms, operations centers, or broadcast facilities where a single high-capacity white-finish enclosure needs to house a complete infrastructure stack cleanly — not for high-density colocation rows where black standard-depth racks are the norm.
