APC Netshelter SX GEN 2 42U Server Rack Enclosure 600MM X 1200MM W/ Sides White - AR3300W2

APC by Schneider Electric AR3300W2 42U NetShelter SX Gen 2 Server Rack Enclosure

The APC NetShelter SX Gen 2 AR3300W2 is a 42U, 600mm-wide by 1200mm-deep freestanding server rack enclosure finished in white — the specification most commonly called for in healthcare, education, and light-commercial IT rooms where aesthetics and access-control matter as much as cable management. At 1991mm tall with a standard 19-inch (48.3 cm) mounting rail layout, it fits the full range of 1U–4U servers, switches, patch panels, and security NVR appliances without modification. If you're speccing a server rack enclosure for a mid-density equipment room and need integrated side-panel security in a white finish, this is where to start.

Key Features

• 42U Usable Capacity: 42 rack units accommodate a full stack — top-of-rack switch, firewall, a dozen 1U servers, and patch panels — without overflow chassis. That eliminates the cost and footprint of a second rack on typical enterprise branch deployments.
• 600mm Width × 1200mm Depth: The 600mm footprint is the narrowest standard rack width that still supports blanking panels, cable managers, and PDUs on both rail sides. The 1200mm depth handles high-airflow 2-post-style server sleds (adjustable mounting from 191mm to 1048mm deep) without forcing you to leave the rear door open — a real factor for cooling and dust ingress.
• Adjustable Mounting Depth (191–1048mm): Rails slide to 1048mm maximum depth, meaning even deep storage arrays and UPS units mount flush and door-close correctly. A fixed-depth rack would leave rear cables snagged against the door — here you dial in the rail position to match the chassis.
• 270° Front Door Swing: The door swings a full 270° and parks flush against the side of the enclosure. In tight equipment rooms where aisles are 900mm or less, this prevents the door from blocking adjacent racks or wall-mounted panels during maintenance — a small spec that matters constantly during adds/moves/changes.
• Keyed Side Panels with Independent Lock: Side panels are included and ship with their own key lock, separate from the door lock. This lets you grant a cabling contractor access to the door (front-of-rack patching) without giving them access to remove side panels and reach internal bus bars or inter-rack cabling — a meaningful physical access-control separation in multi-tenant or colocation environments.
• Keyed Front Door: Front door key lock provides basic deterrence against casual access in shared spaces — hallway IDF closets, open-plan server rooms, or classroom AV racks where the enclosure isn't behind a dedicated locked room.
• Adjustable Leveling Feet: Adjustable feet let you level the enclosure on uneven raised-floor tiles or concrete slabs without shimming. Combined with the 2128mm packaged height, the unit ships on a pallet and installs without a crane — two people and a hand truck.
• White Finish: White enclosures are the standard call for healthcare, education, and retail environments where grey/black racks look out of place. Matching rack accessories — PDUs, blanking panels, cable managers — are widely available in this finish from APC's NetShelter accessory line.
• Standard 19-Inch Rail Pattern: The 48.3cm (19
