APC by Schneider Electric AR3307W2 48U Server Rack Enclosure
Overview
The APC NetShelter SX Gen 2 AR3307W2 is a 48U, 600mm-wide by 1200mm-deep server rack enclosure finished in white — the right choice when your data center or server room layout demands a specific color-coded zone, or when ceiling height and floor space are already budgeted for a 48U footprint. At 225.8 cm tall and 146.2 kg unloaded, this is purpose-built infrastructure, not a field-adjustable bracket. Plan your installation with that mass in mind before you roll it into position.
Key Features
- 48U Rack Height: 48 rack units provide enough vertical space to populate a full compute stack — from top-of-rack switches and patch panels down through multiple 2U servers and a UPS shelf — without forcing a second cabinet and the cabling overhead that comes with it.
- 600mm Width, 1200mm Depth: The 600mm wide footprint fits standard 19-inch rackmount equipment cleanly. The 1200mm depth accommodates modern high-density servers with rear-exhaust cable runs and power distribution units without cramping airflow paths.
- 19-Inch Rail Standard: Universal 19-inch mounting rails mean virtually every commercial server, switch, and appliance drops in without adapter hardware — straightforward provisioning for mixed-vendor deployments.
- Included Side Panels: Sides ship with the unit. Enclosed panels improve directed airflow from front to rear, reducing hot-spot risk in rows where blanking panels alone are insufficient.
- White Finish: The white colorway is a practical differentiator in environments that color-code zones by function or clearance level, or in edge deployments (retail back-of-house, clinical spaces) where a black cabinet would look out of place.
- Floor-Standing, Non-Rack-Mountable: This enclosure is a freestanding floor unit — not a chassis designed to slide into another rack. It requires level, load-bearing flooring rated for at least 146.2 kg of enclosure weight plus the full equipment payload above it.
- Gen 2 Construction: The NetShelter SX Gen 2 line updates cable management routing and structural reinforcements over the original SX series — relevant when you're cabling dense 10GbE or fiber runs that need organized, repeatable dressing.
Integration and Compatibility
The AR3307W2 accepts standard 19-inch equipment across server, networking, storage, KVM, and power distribution categories. APC's own Smart-UPS and Symmetra product lines integrate directly with the NetShelter SX rail system, and third-party PDUs from common vendors mount without modification. If you're building out a monitored environment, APC's NetBotz rack access and environmental monitoring units are designed to attach to this enclosure family. For adjacent network switches and top-of-rack connectivity, the 1200mm depth leaves adequate rear clearance for cable egress. Buyers pairing this with APC by Schneider Electric UPS and PDU products will find the rail spacing and mounting positions consistent across the SX Gen 2 family. Review the full server rack enclosures category for companion units, accessories, and alternative depths.

Frequently Asked Questions
Q: What is the rack unit capacity of the AR3307W2?
A: The AR3307W2 provides 48U of usable rack space, accommodating standard 1U through 4U and larger equipment.
Q: Does the AR3307W2 ship with side panels?
A: Yes, side panels are included with this enclosure as indicated by the 'W Sides' designation in the product name.
Q: What are the external dimensions of the AR3307W2?
A: The enclosure measures 225.8 cm in height. The rack opening is 600mm wide by 1200mm deep, following the NetShelter SX Gen 2 form factor.
Q: How much does the AR3307W2 weigh unloaded?
A: The empty enclosure weighs 146.2 kg. Verify that your floor loading capacity accounts for this plus the full equipment payload before installation.
Q: Can the AR3307W2 be rack-mounted inside another enclosure?
A: No. The AR3307W2 is a freestanding floor unit and is not designed to be mounted inside another rack or cabinet.
Q: What rail width does the AR3307W2 support?
A: It supports the standard 19-inch rack width used by virtually all commercial server, networking, and power distribution equipment.
The AR3307W2 is the unit I'd spec when a project calls for a full 48U column in a white finish — most commonly in clinical or retail edge rooms where aesthetics get reviewed alongside function. The 146.2 kg empty weight is not a casual figure; on a raised-floor data center tile rated for 1,000 lbs/sq ft that's fine, but in a concrete slab retail back-room you're doing a point-load calculation before this cabinet goes in.
Technical Highlights:
- 48U x 600x1200mm footprint: Enough vertical space for a complete converged stack — compute, switching, storage, and UPS — in a single cabinet, which simplifies cable runs and power circuits versus splitting across two 24U units.
- 1200mm depth: Modern dual-socket servers with rear-exit cabling and rear-mounted PDUs fit without rear-door interference. That extra depth versus a 1000mm cabinet matters when you're running structured fiber alongside power.
- White colorway with included sides: Side panels included means no separate accessory order to close the enclosure. White finish survives customer-facing or auditor-visible installs where a black cabinet would draw a comment.
Deployment Considerations:
- At 225.8 cm tall, verify ceiling clearance before delivery — this cabinet will not clear a standard 8-foot drop ceiling with the casters extended; you may need to remove casters or pre-plan the install path through the building.
- The 146.2 kg empty weight means two-person minimum for repositioning; specify a loading dock or freight elevator on the site survey before the unit ships.
For a clinical IT closet, edge compute room in a retail chain, or any environment where equipment color-coding is a facilities requirement, the AR3307W2 delivers a full 48U white enclosure without a custom paint order or a field modification.
