APC by Schneider Electric Netshelter SX 42U 750MM Wide X 1070MM Deep Networking Enclosure - AR3140W

APC by Schneider Electric AR3140W 42U NetShelter SX Networking Enclosure

Overview

The AR3140W is a free-standing 42U rack enclosure from APC by Schneider Electric's NetShelter SX line, configured in white — a finish commonly specified for data closets, structured cabling environments, and network-forward deployments where visual identification of equipment rows matters. At 750mm wide and 1070mm deep, this enclosure accommodates full-depth active networking gear: top-of-rack switches, patch panels, cable management arms, and high-density 1U/2U appliances without forced cable compression at the rear.

Key Features

• 42U Capacity: 42 rack units in a single footprint gives you room to consolidate an entire IDF or MDF stack — switches, patch panels, UPS, and cable management — without splitting across two enclosures and the associated inter-rack cabling overhead.
• 750mm Width: The 750mm wide profile supports standard 19-inch rack equipment and leaves usable side clearance for vertical cable managers on either edge — wider than the 600mm baseline, which matters when you're routing high-density fiber or bundled Cat6A runs. Consider this alongside a network rack or enclosure comparison if footprint is constrained.
• 1070mm Depth: 1070mm depth handles full-depth chassis — hyperconverged nodes, blade enclosures, and high-port-count switches — without rear-door clearance compromises. Factor this into your raised-floor or hot-aisle containment layout early.
• Free-Standing Configuration: Ships as a self-supporting unit, so no wall anchoring or seismic bracing is required for standard installations — reduces installation labor in finished data closets or network rooms where wall penetration isn't permitted.
• White Finish: The white colorway is a practical differentiator in multi-row environments where color-coding separates network infrastructure from power or compute rows. It also improves ambient light reflection in low-ceiling closets.

Integration & Compatibility

The AR3140W is designed to integrate with APC's NetShelter SX accessory ecosystem — side panels, roof panels, blanking panels, power distribution units, and cable management options attach using the standard SX rail and mounting hole pattern. Standard EIA-310 19-inch rack spacing means virtually all enterprise networking and security appliances mount without adapter brackets. Pair it with an appropriate rack PDU to distribute power across the enclosure. For structured cabling environments, verify that your chosen cable management arms and horizontal managers fit the 750mm width before ordering.

Frequently Asked Questions

Q: What is the rack unit capacity of the AR3140W?

A: The AR3140W provides 42U of usable rack space in a free-standing enclosure.

Q: What are the external dimensions of the AR3140W?

A: The enclosure is 750mm wide and 1070mm deep. Exact height follows standard 42U NetShelter SX dimensions — consult the APC product datasheet for precise overall height with and without feet/casters.

Q: What color is the AR3140W?

A: White. This is the white variant of the NetShelter SX 42U 750x1070mm enclosure, as distinct from the standard black version.

Q: Is the AR3140W compatible with standard 19-inch rack equipment?

A: Yes. The AR3140W uses standard EIA-310 19-inch mounting rails, compatible with the vast majority of enterprise networking, security, and compute equipment.

Q: Can the AR3140W be used with APC NetShelter SX accessories?

A: Yes. The SX line shares a common accessory ecosystem — side panels, blanking panels, PDUs, and cable management products designed for the NetShelter SX attach directly to this enclosure.
