APC by Schneider Electric AR3107B2 48U Server Rack Enclosure
Overview
The APC by Schneider Electric AR3107B2 is the NetShelter SX Gen 2 48U server rack enclosure, built for data center and server room deployments where organized, high-density equipment housing is non-negotiable. At 600mm wide and 1070mm deep with 48 usable rack units, it accommodates the full range of standard 19-inch rackmount hardware — from 1U switches to deep dual-power servers — without creative workarounds. Side panels are included, making this a complete enclosure ready for floor deployment out of the box. If you're speccing a medium-to-large server room, a network operations center, or expanding a structured rack environment, the AR3107B2 is a workable centerpiece for a network and server infrastructure build.
Key Features
- 48U Rack Height: 48 rack units means you can house a fully populated mix of servers, patch panels, KVM drawers, and PDUs without running out of vertical space mid-build. This is the right size for server rooms that have moved past the 24U starter phase and need room to grow.
- 600mm x 1070mm Footprint: The 600mm width is standard for 19-inch rackmount gear, and the 1070mm depth handles modern servers with dual PSUs and full-length GPU cards without cable management becoming a nightmare. Verify your floor tile spacing before ordering — 600mm-wide racks in a 24-inch tile grid leave little room for airflow management on the sides.
- Included Side Panels: Shipping with side panels means you don't need to order enclosure accessories separately to achieve a finished, secure cabinet. Panels contribute to front-to-back airflow discipline by preventing bypass airflow from mixing into adjacent hot aisles.
- 19-Inch Rack Standard: Universal 19-inch mounting rails mean every standard rackmount device — switches, servers, storage arrays, UPS units from any vendor — drops in without adapter kits or custom hardware.
- Black Finish: Matches the standard data center and server room aesthetic. If you're deploying into a raised-floor environment with existing black enclosures, the AR3107B2 fits the visual standard without a mixed-cabinet look.
- Floor-Standing (Non-Rack-Mountable) Form Factor: This is a standalone floor enclosure, not a chassis intended for nesting inside another rack. Plan your floor space and cable management paths accordingly — it needs clear vertical clearance plus front and rear door swing room.
- 134.88 kg Assembled Weight: At nearly 135 kg fully assembled (before equipment), site planning must account for floor loading limits — especially on raised access floors. Check your floor's weight rating against your total populated rack load before placing the order.
Integration and Compatibility
The AR3107B2 integrates directly into the broader APC by Schneider Electric NetShelter ecosystem, including APC rack PDUs, blanking panels, cable management accessories, and hot/cold aisle containment systems. Standard 19-inch rail spacing means compatibility with virtually any rackmount device. For structured cabling, pair with a 1U or 2U patch panel to keep copper and fiber runs organized across a structured cabling build. If you're sizing UPS capacity for this enclosure, review your per-rack wattage against APC's rack-mount UPS lineup. For cooling and rack accessory planning, the 1070mm depth supports rear-mounted cable management arms on most enterprise server platforms.
Frequently Asked Questions
Q: What is the internal usable depth of the AR3107B2?
A: The AR3107B2 is rated at 1070mm external depth. Usable internal depth for equipment will be somewhat less after accounting for door and rail hardware — consult the APC NetShelter SX Gen 2 datasheet for exact internal rail-to-rail clearance before speccing deep dual-PSU servers.
Q: Does the AR3107B2 come with side panels included?
A: Yes — side panels are included with this enclosure, giving you a complete, enclosed cabinet without requiring separate accessory orders.
Q: Is the AR3107B2 compatible with standard 19-inch rackmount equipment?
A: Yes. The AR3107B2 uses standard 19-inch rack rails, making it compatible with virtually any rackmount server, switch, storage array, patch panel, or UPS built to the EIA-310 19-inch standard.
Q: What is the weight of the AR3107B2 enclosure before equipment is loaded?
A: The AR3107B2 weighs 134.88 kg (approximately 297 lbs) assembled. Factor this into floor loading calculations — particularly on raised access floors — before deploying.
Q: Can the AR3107B2 be used in a hot/cold aisle containment setup?
A: The NetShelter SX Gen 2 series is designed to work with APC hot/cold aisle containment accessories. Confirm specific containment kit compatibility with the AR3107B2's dimensions against APC's containment accessory selector before ordering.
The AR3107B2 is one of those enclosures that looks straightforward on paper — 48U, 600x1070mm, black, side panels included — but the 134.88 kg assembled weight is the number I always flag first when a client is planning a raised-floor installation. That weight before any equipment gets loaded means you need to know your floor tile rating cold before this rack goes on a purchase order.
Technical Highlights:
- 48U Capacity: 48 rack units gives you room for a fully loaded server environment — mix of 1U/2U servers, ToR switches, cable managers, and a rack-mount UPS — without splitting your deployment across two enclosures and doubling your cabling overhead.
- 1070mm Depth: Deep enough to house current-generation dual-PSU rack servers with cable management arms attached. Shallower 800mm enclosures force cable arm compromises or require PSU extensions on some platforms — this depth avoids that constraint.
- Side Panels Included: Containing bypass airflow matters at density. Side panels ship in the box so you're not waiting on a separate accessory order to close the enclosure and enforce front-to-back airflow from day one.
Deployment Considerations:
- At 134.88 kg unloaded, calculate total populated rack weight against your raised floor or concrete slab rating before finalizing placement — a fully populated 48U rack can exceed 500 kg in dense compute builds.
- The 600mm width is standard, but in a 24-inch floor tile grid it leaves minimal side clearance — map your aisle widths and cable tray routes before committing to rack placement in a dense row.
The AR3107B2 is the right call for a medium-density server room build or NOC expansion where you need a complete, floor-standing 48U enclosure that fits APC's broader power and containment accessory ecosystem without custom hardware.
