APC Netshelter SX GEN 2 42U Server Rack Enclosure 600MM X 1070MM W/ Sides Black - AR3100B2

APC by Schneider Electric AR3100B2 42U Server Rack Enclosure

Overview

The APC by Schneider Electric AR3100B2 is a 42U NetShelter SX Gen 2 server rack enclosure measuring 600mm wide by 1070mm deep, finished in black. Designed for data centers, server rooms, and enterprise IT closets, it provides a structured, cable-managed home for 19-inch rack-mount equipment. At 78.39 inches tall and 269.27 lb, this is a full-height, floor-standing enclosure — plan your floor load and ceiling clearance before specifying it.

Key Features

• 42U Capacity: 42 rack units of usable vertical space gives you room to mount dense server, switch, and patch panel configurations without splitting across multiple enclosures — critical when consolidating infrastructure in a single bay.
• 600mm Width / 1070mm Depth: The 1070mm depth comfortably accommodates today's 2S rack servers and high-density switch chassis without forcing cable bend-radius compromises at the rear. The 600mm width fits the standard row pitch in most raised-floor data centers.
• 19-Inch Universal Mounting: Standard EIA-310 19-inch rack rail spacing means virtually any enterprise server, switch, or UPS with rack ears drops straight in — no adapter plates, no custom mounting.
• 278.39-Inch Height / Floor-Standing Form: At just over 78 inches, this enclosure sits flush against a standard 84-inch drop ceiling clearance zone. Non-rack-mountable by design — it anchors to the floor, providing stability for top-heavy loaded configurations.
• 269.27 lb Empty Weight: Factor this into your floor load calculation before populating. A fully loaded 42U enclosure with servers, PDUs, and cable management can exceed 1,500 lb total — structural review is not optional on upper floors or raised flooring systems.
• Black Finish: Standard black powder coat matches the majority of commercial data center aesthetics and blends with hot-aisle/cold-aisle containment panels if you add containment later.
• Side Panels Included: Sides ship with the unit, so the enclosure arrives as a complete, sealed cabinet — useful where airflow management or physical security of installed equipment matters from day one.

Integration & Compatibility

The AR3100B2 accepts standard 19-inch rack-mount equipment across server rack enclosures and IT infrastructure categories. It pairs directly with APC's NetShelter accessory ecosystem — vertical and horizontal cable management panels, blanking panels, and PDUs all mount without modification. If you are building out a structured cabling environment alongside your compute stack, pair this with a PoE switch or patch panel for clean front-to-back cabling. For power protection planning, APC's own UPS and PDU lines are dimensioned to fit this enclosure's 600mm width. Review the data center planning guide for floor load, airflow, and power capacity considerations before finalizing your rack layout.

Frequently Asked Questions

Q: What is the usable rack unit capacity of the AR3100B2?

A: The AR3100B2 provides 42U of usable vertical space for 19-inch rack-mount equipment.

Q: What are the external dimensions of the AR3100B2?

A: The enclosure is 600mm wide by 1070mm deep and 78.39 inches (199.1 cm) tall.

Q: How much does the AR3100B2 weigh empty?

A: The AR3100B2 uses standard 19-inch (EIA-310) rack mounting, compatible with virtually all enterprise servers, switches, and rack accessories.

Karl Wilson

The AR3100B2 is the enclosure I spec when a customer needs a full-height 42U bay and cannot compromise on depth — the 1070mm interior clears the rear cable tray on virtually every 2S server I have deployed, including dual-PSU configurations with factory power cords still attached. At 269.27 lb empty, this is not a unit you move after it is loaded; site survey the floor rating before it arrives.

Technical Highlights:

• 1070mm Depth: Enough clearance for long-chassis servers plus rear PDU mounting without forcing cable routing compromises — critical in high-density compute rows where every inch of bend radius matters.
• 42U Capacity: Fits a full-density server stack: 10x 2U servers, top-of-rack switch, patch panel, and dual PDUs without splitting across enclosures, which simplifies power and network zoning.
• 269.27 lb Empty Weight: Structural planning is mandatory. On a raised floor, verify tile and stringer ratings before positioning; on concrete slab, verify point load limits at the leveling feet — a populated 42U enclosure regularly exceeds 1,200 lb total.

Deployment Considerations:

• The 600mm width fits standard row pitch in most raised-floor environments, but verify aisle width if you are adding hot-aisle containment — the door swing on a 1070mm-deep cabinet needs clearance behind it as well as in front.
• Side panels ship with the unit, which is convenient for physical security, but plan your blanking panel order separately — the AR3100B2 does not include blanking panels, and open Us in a loaded cabinet will short-circuit your cold-aisle containment airflow.

This enclosure is the right call for a dedicated compute row in a purpose-built server room or colocation cage where you need maximum U-count, deep-chassis clearance, and a sealed cabinet from day one — not a general-purpose IT closet where a shallower 800mm unit would do the same job at lower cost.
