APC NetShelter SX 12U Rack Black — 600x900mm

The APC NetShelter SX AR3003 is a 12U server rack enclosure designed for edge computing deployments where space is at a premium. With its compact 658mm height, this rack is specifically engineered to fit underneath desks, cabinets, and in ROBO (remote office/branch office) environments while providing professional-grade protection for your networking equipment. Built to industry standards, this enclosure delivers the reliability APC is known for, making it an ideal foundation for housing your UniFi switches, consoles, NVRs, and other critical infrastructure components in a secure, organized manner.

• Complete installation package includes casters, leveling feet, lockable doors with keys, roof panel, and side panels for immediate deployment
• 600mm width x 900mm depth provides ample space for standard rack-mount equipment while maintaining a manageable footprint
• Low to medium density ready with compatibility for APC PDUs, mounting accessories, airflow management, and cable management solutions
• Secure and discrete design with lockable front and rear doors to protect valuable equipment in accessible office environments

This rack enclosure serves as the professional backbone for growing UniFi deployments, providing the physical infrastructure needed to keep switches, patch panels, NVRs, and UPS systems organized and protected. The shorter 12U form factor makes it particularly well-suited for distributed deployments across multiple branch locations or for integrators who need to install equipment in spaces where traditional full-height racks won’t fit. With broad compatibility across APC’s accessory ecosystem, you can easily add power distribution, cooling, and cable management as your installation requirements evolve.
