APC by Schneider Electric AR9307SP-R 48U NetShelter SX3K Deep Rack Enclosure
Overview
The APC by Schneider Electric AR9307SP-R is a 48U, 600mm wide by 1200mm deep rack enclosure engineered for high-density server, storage, and network deployments where airflow management, cable organization, and structural load capacity are non-negotiable. Rated to hold 3,500 lbs of equipment, the NetShelter SX3K is built for data center floors and mission-critical equipment rooms that go well beyond the capacity limits of standard commercial enclosures. If you are building or expanding a high-density compute or security infrastructure rack, this is the enclosure to evaluate.

Key Features
- 48U of Usable Rack Space: Forty-eight rack units of 19-inch EIA-standard mounting space means you can consolidate servers, patch panels, NVRs, and power distribution into a single enclosure — reducing floor footprint and cabling complexity across high-density deployments.
- 1200mm Deep Cabinet: The 1200mm depth accommodates full-length 1U and 2U servers, high-density network video recorders, and deep switching gear without forcing equipment to overhang rear rails — a common problem with shallower 800mm or 1000mm alternatives.
- 3,500 lb Static Load Rating: Purpose-built for environments that push weight limits — fully loaded blade chassis, dense storage arrays, and UPS systems can be installed without concern for enclosure deflection or rail failure that plagues lighter-duty racks.
- Reusable Ramp System Included: The integrated reusable ramp system lets you roll heavy equipment directly into the cabinet during installation — a practical advantage in equipment rooms without overhead lifts or in data center deployments where rack loading is a recurring task.
- Optimized Airflow Architecture: The enclosure design channels front-to-rear airflow efficiently, which is critical when deploying high-watt servers or densely loaded UPS and power distribution equipment that generates significant heat per rack unit.
- Cable Management Integration: Side panels and rear access points are designed to support structured cabling runs, keeping patch cables, power feeds, and fiber organized — which directly reduces troubleshooting time and lowers risk of accidental disconnection during maintenance.
- Pre-Installed Casters and Leveling Feet: Factory-fitted casters let you position the loaded cabinet during initial installation, then leveling feet lock it in place on the data center floor — no separate hardware sourcing or retrofitting needed.
- Side Panels Included: Enclosed sides improve containment for hot-aisle/cold-aisle configurations and limit unauthorized lateral access to rack equipment, relevant in co-location and secure equipment room environments.
Integration and Compatibility
The AR9307SP-R (often searched as AR9307SP R) uses standard 19-inch EIA rail spacing, making it compatible with virtually all rackmount server, storage, and networking equipment. It is specifically noted as compatible with the SURT48RMXLBP extended battery module, making it a natural pairing in APC Smart-UPS RT deployments requiring extended runtime capacity. The 19-inch standard also supports rackmount accessories from third-party vendors across power strips, cable managers, and blanking panels without modification.

Frequently Asked Questions
Q: What is the maximum load capacity of the AR9307SP-R?
A: The AR9307SP-R NetShelter SX3K is rated for a 3,500 lb static load capacity, making it suitable for high-density server, storage, and UPS deployments that exceed the limits of standard commercial enclosures.
Q: How deep is the AR9307SP-R interior, and will it fit full-length 1U servers?
A: The AR9307SP-R has a 1200mm (approximately 47 inch) depth. This accommodates full-length rackmount servers, deep UPS units, and high-density storage equipment without rear overhang issues.
Q: Does the AR9307SP-R include a ramp for loading heavy equipment?
A: Yes. A reusable ramp system is included in the box, allowing you to roll heavy rackmount equipment directly into the cabinet during installation.
Q: What rack unit height does the AR9307SP-R provide?
A: The AR9307SP-R provides 48U of standard 19-inch EIA rackmount space.
Q: Does the AR9307SP-R ship with side panels and casters?
A: Yes. Side panels and pre-installed casters are included, along with leveling feet, mounting hardware, baying hardware, and a user manual.
Q: What equipment is the AR9307SP-R specifically noted as compatible with?
A: APC lists the AR9307SP-R as compatible with the SURT48RMXLBP extended battery module, making it a direct fit for Smart-UPS RT extended runtime configurations.
The AR9307SP-R is the enclosure you specify when standard 800kg-rated racks simply are not an option — the 3,500 lb static load rating puts this in a different class from most commercial cabinets, and the 1200mm depth means you are not forcing blade chassis or long-body servers into a frame that fights you at the rear.
Technical Highlights:
- 3,500 lb Load Rating: At 663.98 lbs empty, this is a heavy cabinet — but that structural mass is what supports the load ceiling. Deploy it where equipment density per rack exceeds what lighter 12-gauge alternatives handle safely.
- 1200mm Interior Depth: Full-depth servers, dual-corded PDUs, and rear cable managers all fit without rear-rail modifications. This is the spec that eliminates the most common retrofit headaches in dense compute rows.
- Reusable Ramp System: An underappreciated inclusion — loading a 48U enclosure with blade chassis or UPS gear without a ramp in a raised-floor environment creates real injury and equipment risk. Factory-included, not an afterthought add-on.
Deployment Considerations:
- At 663.98 lbs empty and overall dimensions of 47.2 x 23.6 x 88.9 inches, confirm your freight elevator and equipment room door clearances before delivery — this cabinet does not fit through standard 36-inch doorways fully assembled.
- The pre-installed casters are load-rated for positioning, not permanent transport of a fully loaded rack. Secure to leveling feet before populating with equipment.
Best-fit scenario: high-density compute or security operations center buildouts where blade density, extended UPS battery strings, and deep storage arrays share a single cabinet footprint under managed hot-aisle/cold-aisle containment.
