Overview
The Eaton SR42UBEXPNDNR3 is a robust 42U 4-post premium open frame rack designed for housing standard 19-inch rackmount equipment in data centers, server rooms, and enterprise environments. As an expansion model, this unit is supplied without side panels, doors, or a top panel, making it ideal for deployments where equipment access, efficient airflow, or baying with existing racks is prioritized. It provides a secure and organized foundation for mission-critical IT infrastructure. Engineered for substantial loads, the SR42UBEXPNDNR3 supports a dynamic and static capacity of 3000 lbs, accommodating a wide range of servers, switches, and other network devices. The front and rear vertical mounting rails feature square holes and are adjustable in quarter-inch increments from 4 to 37 inches, enabling precise alignment and optimal use of internal depth. This flexibility ensures compatibility with diverse equipment footprints and simplifies future upgrades. Deployment and management are streamlined through practical design elements. The rack ships fully assembled with preinstalled 3-inch casters for easy positioning and heavy-duty levelers for stable installation on uneven floors. Integrated tool-less button-mount slots allow for the convenient installation of up to four 0U compatible PDUs and cable managers, optimizing power distribution and cable routing without consuming valuable rack space. All components are grounded to the frame, with dedicated front and rear threaded grounding points for reliable connection to facility earth ground.
