APC Netshelter SX Server Rack GEN 2 52U 2436H X 800W X 1200D MM with Sides - AR3388B2

APC by Schneider Electric AR3388B2 52U NetShelter SX Gen 2 Server Rack Enclosure with Sides

Overview

The APC by Schneider Electric AR3388B2 is a 52U, second-generation NetShelter SX rack enclosure designed for data centers, server rooms, and high-density equipment deployments where organized cable management, structural rigidity, and standardized form factors are non-negotiable. At 2436mm tall, 800mm wide, and 1200mm deep, this enclosure provides enough physical real estate to house full-depth servers, networking gear, and cable management accessories without compromise. The white finish and included side panels make it a natural fit for co-location environments and enterprise data halls where visual organization and airflow containment are part of the facility design spec.

Key Features

• 52U Rack Capacity: 52U of usable rack space is meaningful headroom — you can fully populate it with 1U servers and still have room for top-of-rack switching, patch panels, and cable management horizontal organizers without cramming. For a typical hyperconverged or blade deployment, that eliminates the premature rack splits that force extra floor space and cross-rack cabling.
• 800mm Width: The 800mm width (vs. the standard 600mm) accommodates wider cable trays, side-by-side patching, and IT equipment with oversized handles or toolless rail systems. If your integrator is working with Cisco UCS, HPE Synergy, or similarly wide-chassis gear, the extra 200mm matters on installation day.
• 1200mm Depth: A 1200mm internal depth handles full-depth servers (most enterprise servers run 700–900mm) and still leaves clearance at the rear for vertical cable managers and high-density patching. You won't be routing cables through active airflow zones to reach the back of a deep chassis.
• Included Side Panels: Side panels ship with the AR3388B2, enabling immediate airflow containment aisle deployment without a separate accessory order. In hot-aisle/cold-aisle layouts, sealed sides prevent bypass airflow that undermines CRAC efficiency — a direct operational cost factor in larger deployments.
• Integrated Cable Management: The enclosure includes structured cable management provisions, keeping power and data cabling organized from day one. Disciplined cable routing reduces troubleshooting time during maintenance windows and protects airflow paths that would otherwise be blocked by bundled cable runs.
• RoHS Compliance: The AR3388B2 carries RoHS certification, confirming restricted hazardous substances compliance for deployments in the EU and for organizations with environmental procurement requirements. Relevant if your facility management team tracks materials compliance at the hardware level.
• White Color (Product Colour: White): The white finish differentiates this unit from the standard black NetShelter SX variants. Purpose-built for environments where visual differentiation by rack row, department, or security zone is part of the physical infrastructure design — common in healthcare IT and financial operations centers.

Integration and Compatibility

The AR3388B2 follows the standard NetShelter SX mounting rail pattern, accepting 19-inch EIA-310 rack equipment universally. APC's own toolless rail kits, blanking panels, and cable management accessories are dimensionally matched to this enclosure. Network infrastructure accessories from third-party vendors designed for 800mm-wide, 1200mm-deep enclosures will integrate without modification. Side panels can be removed for edge-to-edge row configurations or aisle containment builds. For environments requiring integrated power distribution, APC vertical PDU options mount directly to internal vertical mounting positions without consuming rack unit space. See our UPS and power distribution category for compatible in-rack power solutions.

The 52U height aligns with standard data center floor tile spacing, and the 2436mm total height fits under typical 3-meter raised floor environments with clearance for overhead cable trays. When planning row layouts, account for the side panel width: the 800mm nominal dimension is the enclosure body — confirm your row spacing accommodates panels before final placement.

Frequently Asked Questions

Q: What is the rack unit capacity of the AR3388B2?

A: The AR3388B2 provides 52U of rack space within a 2436mm tall enclosure. This is one of the largest standard U-count configurations in the NetShelter SX line, suitable for high-density server or networking deployments.

Q: Does the AR3388B2 include side panels?

A: Yes. Side panels are included with the AR3388B2 as specified in the product configuration. They enable immediate use in airflow-contained aisles without a separate accessory purchase.

Q: What are the external dimensions of the AR3388B2?

A: The enclosure measures 2436mm in height, 800mm in width, and 1200mm in depth. Always confirm ceiling height and row spacing accommodate these dimensions, including the installed side panels, before deployment.

Q: Is the AR3388B2 RoHS compliant?

A: Yes. The AR3388B2 carries RoHS compliance certification, confirming it meets restricted hazardous substances requirements for EU and environmentally regulated procurement environments.

Q: What is the difference between the AR3388B2 and the standard black NetShelter SX variants?

A: The AR3388B2 is finished in white and is designated a Gen 2 configuration. The white finish is typically specified for environments using color-coded rack rows or where visual differentiation between infrastructure zones is part of the data center design standard.

Q: Will standard 19-inch rack equipment mount in the AR3388B2?

A: Yes. The AR3388B2 uses standard EIA-310 19-inch mounting rails, accepting virtually all rack-mount servers, switches, patch panels, and accessories from any vendor conforming to that standard.

The AR3388B2 is a 52U, 800mm-wide, 1200mm-deep NetShelter SX Gen 2 enclosure — and the white finish is the spec detail that tells you exactly where this unit belongs. It's not a cosmetic choice; white racks are specced when facility managers need visual zone differentiation by row, department, or security classification in a larger hall. If you're fitting out a single mixed-use server room, the standard black variants do the same job mechanically.

Technical Highlights:

• 52U Capacity: At 2436mm tall, this is the largest practical U-count in a standard floor-standing enclosure. Fully populating it with 1U equipment means 52 devices per rack position — relevant when you're calculating floor density against raised-floor load ratings and cooling zones.
• 800mm Width with 1200mm Depth: The combination of 800mm width and 1200mm depth is the spec pairing that matters for full-depth enterprise hardware. The extra width over a 600mm enclosure leaves room for vertical cable managers and rear PDU mounting without routing cables through active equipment airflow.
• RoHS Compliance: For procurement teams sourcing into EU facilities or under environmental compliance mandates, RoHS certification on the AR3388B2 means the enclosure itself doesn't create a materials documentation gap in the hardware BOM.

Deployment Considerations:

• The 2436mm height requires confirmation against ceiling clearance and overhead cable tray clearance before rack placement — this is not a low-profile unit and won't fit under a standard 8-foot drop ceiling without modifications.
• Side panels are included, but if you're building an aisle containment system with blanking panels and brush strips, order those separately — the AR3388B2 ships with the enclosure and sides only, not a full containment kit.

This enclosure is the right specification for an enterprise data hall buildout or co-location cage deployment where white rack rows are part of the zone design standard, you're running full-depth hardware that needs the 1200mm depth, and your procurement spec requires RoHS documentation at the enclosure level.
