APC Netshelter SX Server Rack GEN 2 42U 1991H X 750W X 1200D MM Without Sides - AR3350B2X609

APC by Schneider Electric AR3350B2X609 42U NetShelter SX Gen 2 Server Rack

Overview

The APC NetShelter SX Gen 2 AR3350B2X609 is a 42U freestanding open-frame server rack engineered for dense IT and physical security infrastructure deployments. At 750 mm wide and 1200 mm deep, it accommodates high-density switching, patch panels, NVR appliances, and server hardware in a single standardized 19-inch enclosure — without the thermal management constraints that come with fully enclosed cabinets. The sideless configuration is a deliberate design choice: it maximizes airflow in high-density rows and allows cable runs, PDU installations, and hot-swap maintenance from any angle without removing panels.

For enterprise security and IT integrators deploying network video recorders, core switching infrastructure, or compute appliances, this rack delivers the footprint discipline and load rating required for production datacenter and server room installations.

Key Features

• 42U Rack Space: 42U of usable space — enough to stack a full NVR stack, PoE switching tier, patch panels, and UPS hardware in one cabinet without splitting across multiple racks. Reduces cable sprawl and simplifies zone-based infrastructure planning.
• 750 mm Width: The 750 mm (approximately 29.5 in) exterior width is the standard IT rack width, fitting standard raised-floor grid spacing and aisle containment systems. Wider than 600 mm alternatives, it provides additional side clearance for PDU mounting and high-density cabling without bumping adjacent equipment.
• 1200 mm Depth: At 1200 mm (approximately 47.2 in) deep, this rack accommodates full-depth 1U and 2U servers, large-format NVR appliances, and deep switching gear without rear-of-rack cable management compromises. Shallow 800 mm racks frequently force awkward cable bend radii on deep equipment — this depth eliminates that problem.
• 1814 kg Maximum Load Rating: The 1814 kg (approximately 4,000 lbs) static load capacity means you can fully populate every U with dense compute or storage hardware without approaching structural limits. Most enterprise NVR and server deployments will run well under 500 kg fully loaded — this rating reflects long-term headroom, not a specification to engineer to.
• 19-Inch EIA-310 Mounting Standard: The standard 48.3 cm (19 in) mounting rail system accepts every major manufacturer's rackmount equipment — Axis, Milestone, Genetec appliances, HPE, Dell, Cisco, Aruba, and generic 1U patch panels all mount without adapter plates.
• Sideless Open-Frame Design: Eliminating fixed side panels is not just a cost reduction — it fundamentally changes maintenance access. Cable dressing, PDU installations, and hot-swap NIC or drive replacements can be done from either side of the rack without tools. In hot-aisle/cold-aisle deployments, it also allows open-rack airflow containment blanking to be added selectively.
• Freestanding Configuration: No floor anchoring or wall attachment required for standard installation, though seismic zones require floor-anchor kit. The freestanding form factor is compatible with raised floor and slab installations.
• Black Finish: Standard black finish aligns with APC NetShelter SX family aesthetics for consistent visual presentation in multi-rack deployments and datacenter environments with co-location aesthetics requirements.

Integration and Compatibility

The AR3350B2X609 is sized for integration with the full APC NetShelter SX accessory ecosystem — side panels, roof blanking panels, caster kits, and power distribution units are available to extend the base rack configuration. The 19-inch rail system accepts any EIA-310-compliant rackmount equipment, covering the full range of network switches, patch panels, servers, and NVR appliances used in physical security and IT infrastructure. For deployments requiring enclosed security or thermal containment, APC's matching side panel kits convert this open-frame rack to a fully enclosed cabinet post-installation.

Integrators building out IP camera infrastructure alongside compute and networking in a single rack will find the 1200 mm depth accommodates full-depth compute nodes and NVR appliances without rear cable management compromises.

Frequently Asked Questions

Q: What is the maximum weight the AR3350B2X609 can support?

A: The AR3350B2X609 is rated for a maximum static load of 1814.4 kg (approximately 4,000 lbs). Most fully populated enterprise rack deployments will fall well below this threshold.

Q: Does the AR3350B2X609 come with side panels?

A: No. This model ships without side panels — that is indicated by the 'Without Sides' designation. Side panels can be added separately via compatible APC NetShelter SX accessory kits if enclosure is required.

Q: What is the interior usable rack space on the AR3350B2X609?

A: The rack provides 42U of usable space within a 1991 mm overall height enclosure, following standard EIA-310 19-inch mounting rail spacing.

Q: Is the AR3350B2X609 compatible with standard 19-inch rackmount equipment?

A: Yes. The rack uses a standard 48.3 cm (19 inch) EIA-310 rail system, which is compatible with virtually all enterprise rackmount servers, switches, patch panels, NVRs, and PDUs from any manufacturer.

Q: What are the overall external dimensions of the AR3350B2X609?

A: The rack measures 1991 mm high x 750 mm wide x 1200 mm deep. Packaged shipping dimensions are 2128 mm H x 853 mm W x 1323 mm D, with a packaged weight of 165.5 kg.

Q: Can the AR3350B2X609 be used as a freestanding rack without floor anchoring?

A: Yes, it is a freestanding rack that does not require wall or floor attachment for standard installation. Floor anchor kits are available and recommended for seismic zones or high-density top-heavy configurations.

The AR3350B2X609 is one of those infrastructure pieces that either fits your deployment plan exactly or it doesn't — and the deciding factor is usually that 1200 mm depth. I specify this rack when the equipment list includes full-depth compute nodes, large-chassis NVR appliances, or high-density switching gear where a 900 mm or 1000 mm rack would force unacceptable cable bend radii off the rear of the equipment. The 1814 kg load rating is well beyond anything you'll realistically populate, but the depth and the sideless open-frame design are the real operational advantages.

Technical Highlights:

• 42U Capacity: Enough vertical space to build out a complete physical security compute stack — NVR appliances, PoE switching tier, patch panels, and rackmount UPS — in a single enclosure without overflow to a second rack.
• 750 mm Width: Fits standard raised-floor grid spacing and hot-aisle/cold-aisle row configurations without modification; wider than 600 mm alternatives to allow PDU side-mounting without crowding cable management.
• Sideless Open Frame: Maintenance access from any angle without panel removal — directly relevant when you're servicing NVR drives, re-dressing cables, or swapping PDU breakers in a live rack under operational pressure.

Deployment Considerations:

• The sideless design maximizes airflow but provides no physical access security — if this rack is in a shared space or co-location environment, pair it with locking side panels and a locking front door to meet physical security requirements.
• At 165.5 kg packaged weight, receiving and positioning this rack requires a loading dock, pallet jack, and at minimum two-person installation — plan logistics before delivery, not after.

This rack is the right specification for a dedicated security operations infrastructure room or a purpose-built server room where you're consolidating NVR compute, network switching, and power distribution into a single high-density footprint. It is not the right choice for a shallow IT closet, an above-ceiling installation, or any environment where the 1200 mm depth exceeds available floor-to-wall clearance.
