APC by Schneider Electric Netshelter SX 42U 600MM Wide X 1070MM Deep Enclosure with Sides - AR3100W

APC by Schneider Electric AR3100W NetShelter SX 42U Free-Standing Rack Enclosure

Overview

The APC by Schneider Electric AR3100W is a 42U, 600mm-wide by 1070mm-deep steel rack enclosure from the NetShelter SX line — a free-standing cabinet built for mixed-use deployments where you need a standardized, secure home for network switches, servers, patch panels, and security infrastructure equipment. At 42U of usable rack space and a 1070mm depth, it accommodates full-depth servers and high-density networking gear without compromise. If you are outfitting a server room, IDF closet, or physical security head-end rack, the APC by Schneider Electric equipment line consistently delivers the structural consistency and standards compliance that enterprise and commercial integrators expect.

The AR3100W ships in white — a practical choice for environments where equipment identification and cleanliness standards matter, such as healthcare, clean-room IT spaces, and retail back-office installations. Steel construction provides the rigidity needed to support a fully populated 42U load, and the enclosure meets UL 2416, UL 60950-1, and EIA-310E standards, giving procurement teams the documentation they need for site acceptance and insurance requirements.

Key Features

• 42U Rack Capacity: Forty-two usable rack units means this cabinet can consolidate an entire edge infrastructure stack — switches, patch panels, UPS, security recorders, and access control hardware — into a single enclosure. That reduces cable runs, simplifies airflow management, and keeps your physical security head-end organized as the system scales.
• 600mm Width / 1070mm Depth: The 600mm width is the standard rack footprint that fits most equipment rails and blanking panels without custom adapters. The 1070mm depth is the critical dimension — it accommodates full-depth enterprise switches and servers (many run 900–1000mm) with room to spare for cable management behind equipment. Shallow 800mm cabinets force cable compromise on deep gear; the AR3100W does not.
• Free-Standing Design: No wall anchoring required, making this enclosure suitable for raised-floor data centers, open-plan IT rooms, and physical security operations centers where wall-mount real estate is limited or prohibited by lease. Repositioning during build-out is practical without structural remediation.
• Steel Construction: Steel framing and panel construction provides the load-bearing stability needed for a densely populated 42U cabinet. Equipment vibration, cable tension, and door cycling over years of service are handled by the material — not by hoping it holds. This matters in 24/7 environments like surveillance head-ends and network operations centers.
• Keyed-Alike Doors and Side Panels: All locking points — front door, rear door, and side panels — use the same key. In multi-rack deployments, keyed-alike simplifies access management significantly: one key per technician covers the full row rather than requiring a key ring per cabinet. For security integrators managing racks across a campus, this is a real operational advantage.
• UL 2416 / UL 60950-1 / EIA-310E Compliance: UL 2416 is the rack and enclosure safety standard required by many enterprise and government facilities for acceptance. UL 60950-1 covers IT equipment safety. EIA-310E is the dimensional standard that guarantees equipment rail spacing compatibility across manufacturers. All three together mean this enclosure will pass facility inspection and accept standard-rail equipment without modification — no surprises at commissioning.
• Mixed-Use Classification: The AR3100W is rated for mixed-use deployments, meaning it is not restricted to passive patch infrastructure — it supports active powered equipment, servers, and network gear within the same cabinet. This matters for consolidated physical security head-ends where IP cameras feed NVRs, NVRs connect to switches, and the whole stack sits in one rack.

Integration and Compatibility

The EIA-310E standard rail spacing ensures compatibility with virtually all 19-inch rack-mount equipment from major vendors — Cisco, HPE, Dell, APC, Bosch, Hanwha, Genetec appliances, and others. The 1070mm depth accommodates full-depth 1U/2U servers and deep switching chassis without needing rear-mount extensions. Side panels and doors are removable for high-density cabling environments, and the keyed-alike hardware means access control across the cabinet is consistent from day one.

For network rack enclosures in physical security deployments, pairing this cabinet with a structured PoE switch and rack-mount UPS keeps the entire IP camera and access control infrastructure on clean, protected power inside a single organized enclosure. The 42U height supports a full NVR-plus-switch-plus-UPS stack with room for patch panels and cable management accessories.

When planning an enclosure deployment, review your deepest piece of equipment first — full-depth servers and redundant power supply chassis often run 950–1000mm, and the AR3100W's 1070mm internal depth handles these without forcing a diagonal mount or rear cable tray sacrifice.

Frequently Asked Questions

Q: What is the internal usable depth of the AR3100W?

A: The AR3100W is specified at 1070mm deep. This is the overall enclosure depth; usable rail-to-rail depth for equipment will be slightly less once accounting for door clearance and cable management, but the 1070mm overall dimension accommodates full-depth enterprise servers and switching chassis that measure up to approximately 950–1000mm.

Q: What standards does the AR3100W meet?

A: The AR3100W is listed to UL 2416 (rack and enclosure safety), UL 60950-1 (IT equipment safety), and EIA-310E (the dimensional standard for 19-inch rack equipment compatibility). These certifications satisfy most enterprise, healthcare, and government facility acceptance requirements.

Q: Is the AR3100W suitable for active powered IT equipment or only passive cabling?

A: The AR3100W carries a mixed-use rating, meaning it is designed to house active powered equipment — servers, switches, NVRs, UPS units — not just passive patch panels or cabling. It is appropriate for consolidated security and IT infrastructure deployments.

Q: Do all the locks on the AR3100W use the same key?

A: Yes. The doors and side panels are keyed-alike, so a single key operates all locking points on the enclosure. In multi-cabinet rows, this simplifies technician access without requiring separate keys per lock point.

Q: What color does the AR3100W ship in?

A: The AR3100W ships in white. This is distinct from the standard black NetShelter SX configurations and is suited for healthcare, clean-room, or retail environments where white equipment is preferred or required.

Q: Can the AR3100W be wall-mounted?

A: No. The AR3100W is a free-standing enclosure and is not designed for wall mounting. It requires floor space and is suitable for raised-floor data centers, IT rooms, and equipment closets with adequate floor area.

Jerry Tildsen

The AR3100W is the configuration I recommend when a physical security head-end needs to consolidate NVRs, managed PoE switches, access control panels, and a rack-mount UPS into a single organized cabinet — specifically because the 1070mm depth eliminates the guesswork around fitting full-depth gear. I have seen integrators order 800mm-deep cabinets to save floor space and then spend an afternoon engineering a workaround for a 950mm switching chassis. The AR3100W avoids that entirely.

Technical Highlights:

• 42U Capacity: Enough vertical space for a complete physical security stack — typically 2U NVR, 1U managed switch, 2U UPS, 1U patch panel, and 24U of active security appliances — with room to expand without ordering a second cabinet immediately.
• EIA-310E Rail Compatibility: The dimensional standard compliance means every standard 19-inch rack-mount device from any major vendor drops in without rail adapters or spacing adjustments — critical when a deployment mixes APC UPS, Cisco switching, and third-party NVR appliances in the same cabinet.
• Keyed-Alike Locking: On a multi-rack row, keyed-alike hardware across doors and side panels means a single technician key covers the full installation — practical in facilities where cabinet access is logged and key management is audited.

Deployment Considerations:

• The white finish is purpose-specific — if this enclosure is going into a standard black-equipment data center row, confirm the aesthetic requirement with the facilities team before ordering. Mixing black and white cabinets in a raised-floor data center is occasionally a facilities compliance issue.
• Verify floor loading capacity before deploying a fully populated 42U cabinet. A densely loaded 42U enclosure with UPS, servers, and switching can exceed 1,000 lbs — raised-floor tiles and structural floor ratings need to be confirmed with the building engineer on older installations.

The AR3100W is the right call for a white-finish mixed-use deployment — healthcare IT closets, retail back-office server rooms, and clean-room environments where equipment color standards are enforced and a full 42U of depth-tolerant rack space is required in a single free-standing footprint.
