APC Netshelter SX Server Rack GEN 2 52U 2436H X 800W X 1200D MM with Sides W - AR3388W2

APC by Schneider Electric AR3388W2 52U NetShelter SX Gen 2 Server Rack

Overview

The APC by Schneider Electric AR3388W2 is a 52U NetShelter SX Generation 2 open-frame server rack enclosure measuring 2436mm high, 800mm wide, and 1200mm deep — configured with side panels and finished in white. At 52U, it provides substantial vertical real estate for high-density server, switching, and storage deployments in data centers, server rooms, and network operations environments where rack organization, cable discipline, and airflow management are non-negotiable. The NetShelter SX line is one of the most widely deployed rack enclosure families in enterprise IT, valued for its accessory ecosystem and predictable compatibility with APC's power distribution and cooling products. If you need a tall, deep enclosure that integrates cleanly with an existing NetShelter SX infrastructure, the AR3388W2 is the white-finish 52U answer.

Key Features

• 52U of Usable Rack Space: Fifty-two rack units give you room to consolidate servers, patch panels, UPS units, KVM switches, and storage arrays into a single enclosure — reducing floor footprint versus splitting across two shorter racks. This matters in colocation environments where cabinet space is billed per U or per rack.
• 800mm Interior Width: The 800mm width accommodates standard 19-inch rack-mount equipment with enough side clearance for cable routing and airflow — wider than the entry-level 600mm NetShelter frames, which means you have room for wider 1U/2U servers and side-exit cable bundles without crowding.
• 1200mm Depth: A 1200mm depth handles today's full-depth servers (most 2U compute nodes run 700–900mm) with cable service clearance at the rear. You won't need to rack servers at an angle or fight with rear cable bundles when using standard-depth 1U or 2U rack servers.
• Integrated Cable Management: Built-in cable management provisions keep power and data runs organized front-to-back and top-to-bottom, which directly reduces troubleshooting time when you need to trace a run under load. Disorganized cabling inside a 52U enclosure becomes a maintenance liability — the built-in management prevents that from the start.
• Side Panels Included: The AR3388W2 ships with side panels, which contain airflow within the rack and reduce hot-air recirculation between adjacent enclosures. In an open server room without full hot-aisle/cold-aisle containment, panels make a measurable difference in inlet air temperature at the equipment.
• White Finish: The white color designation (W suffix) suits deployments where aesthetics or facility standards require non-standard-black enclosures — common in healthcare environments, broadcast operations centers, and campus IT closets where visibility and cleanliness standards differ from traditional data center norms.
• RoHS Compliant: RoHS compliance confirms the enclosure is manufactured without restricted hazardous substances, satisfying procurement requirements for EU-regulated environments and corporate sustainability procurement policies that mandate RoHS-certified hardware.

Integration and Compatibility

The AR3388W2 is part of APC's NetShelter SX Gen 2 rack enclosure family, which means it accepts the full breadth of APC rack accessories — including blanking panels, cage nut kits, cable managers, roof fan trays, and side-panel extensions — without modification. If your deployment includes rack-mount UPS units from APC's Smart-UPS or Symmetra lines, those units are sized and tested against NetShelter SX internal clearances. The 800mm width also accommodates standard 19-inch network switches, patch panels, and 1U/2U servers from any vendor. For environments already running a mixed-enclosure infrastructure, the NetShelter SX accessory cross-compatibility means you're not locked into a single-vendor rail or cable management approach.

For deployments planning physical security alongside IT infrastructure, the AR3388W2 can house network video recorders and server-class VMS appliances in a properly organized, ventilated enclosure — a common requirement in enterprise security operations centers where the NVR stack sits in the same rack room as the core switching infrastructure.

Before ordering, confirm floor load capacity at your installation site — a fully loaded 52U enclosure with servers, storage, and UPS can easily exceed 1,000 kg. Also verify door clearance for the 1200mm depth, which is the most common overlooked dimension when rolling racks into existing server closets.

Frequently Asked Questions

Q: What does the 'W' suffix in AR3388W2 indicate?

A: The 'W' suffix designates the white finish variant of this NetShelter SX Gen 2 enclosure. The same enclosure configuration is available in black under a different model number. White is commonly specified for healthcare, broadcast, and campus IT environments with aesthetic or facility standards that differ from standard data center black.

Q: Does the AR3388W2 include side panels?

A: Yes. The AR3388W2 is specified as shipping with side panels. Side panels help contain airflow within the enclosure, which reduces hot-air recirculation between adjacent racks in open-room deployments without full hot-aisle/cold-aisle containment.

Q: Is the AR3388W2 RoHS compliant?

A: Yes, the AR3388W2 carries RoHS compliance certification, confirming it is manufactured without the restricted hazardous substances covered by the RoHS directive. This satisfies EU regulatory requirements and corporate procurement policies mandating RoHS-certified hardware.

Q: What internal depth does the AR3388W2 actually provide for equipment?

A: The overall enclosure depth is 1200mm. Internal usable depth will be somewhat less once front and rear door frames are accounted for — but at 1200mm overall, this enclosure comfortably handles full-depth 2U servers (typically 700–900mm) with rear cable service clearance remaining. Verify internal rail spacing from APC's configuration specs if you're rack-mounting equipment with tight depth tolerances.

Q: Will standard 19-inch rack equipment fit the AR3388W2?

A: Yes. The AR3388W2 is an 800mm-wide NetShelter SX enclosure that accommodates standard EIA 19-inch (482.6mm) rack-mount equipment — which covers virtually all servers, switches, storage arrays, patch panels, and UPS units built to the 19-inch rack standard.

Q: Does the AR3388W2 include cable management hardware?

A: Yes, cable management is specified as included with the AR3388W2. This provides built-in provisions for routing and organizing power and data cabling front-to-back within the enclosure, reducing clutter in a 52U configuration where cable discipline is essential for airflow and maintainability.

Jerry Tildsen

The AR3388W2 is a specification I see come up specifically when a facility has a visual standards requirement or a healthcare procurement policy that mandates non-black enclosures — the white finish is the differentiator here, not a cosmetic afterthought. At 52U and 1200mm deep, this enclosure is sized for serious compute density, and the included side panels tell me the buyer is thinking about airflow containment from day one rather than retrofitting panels later.

Technical Highlights:

• 52U Capacity: Fifty-two rack units in a single enclosure is the ceiling for most standard-height server room deployments — you can consolidate an entire mid-size server environment into one cabinet, which simplifies physical security, power distribution planning, and future expansion without adding another rack footprint.
• 800mm x 1200mm Footprint: The 800mm width is the critical dimension — it's wider than entry 600mm frames and matches the APC accessory ecosystem designed for this chassis width. The 1200mm depth means you're not compromising on rear cable service clearance even with the longest 2U compute nodes.
• RoHS Certification: In regulated procurement environments — particularly healthcare and EU-based data center buildouts — RoHS compliance is a hard gate requirement, not a preference. Having it confirmed on the AR3388W2 removes a documentation step from the procurement workflow.

Deployment Considerations:

• At 52U with a 1200mm depth, floor loading is a real pre-installation check — fully populated racks in this size class can exceed 1,000 kg. Confirm your raised floor tile rating or concrete slab load capacity before positioning the enclosure.
• The 1200mm overall depth is the spec to verify against your room's door clearance and aisle width before delivery — it's the most common oversight when rolling a tall, deep enclosure into an existing server closet with a standard 36-inch doorway.

This enclosure is the right specification for a healthcare IT room, broadcast operations center, or campus NOC where white is a facility standard and the team needs a full 52U of usable depth without sourcing side panels as a separate line item.
