Overview
The Eaton SR42UBEXP is a 42U SmartRack expandable server rack enclosure designed to provide a robust and secure housing solution for standard 19-inch rackmount equipment in dynamic IT environments. Optimized for baying applications, this model is intentionally shipped without side panels, facilitating seamless integration into multi-cabinet rows within data centers and enterprise campus networks. It addresses the critical need for secure, high-density equipment deployment while allowing for flexible, scalable infrastructure growth. This SmartRack enclosure supports a substantial stationary load capacity of up to 3500 lbs, accommodating a wide range of mission-critical hardware, from servers and storage to networking devices. Its front and rear vertical mounting rails are adjustable in quarter-inch increments, providing a versatile internal depth from 4 to 37 inches to suit diverse equipment requirements. The design also incorporates features such as perforated front and rear doors to ensure optimal airflow, which is crucial for maintaining proper operating temperatures for high-performance equipment. Deployment and ongoing management are streamlined through thoughtful design elements. The SR42UBEXP comes equipped with preinstalled casters for easy maneuverability during initial setup, complemented by levelers to secure its final position. Cable management is simplified via an open bottom and a quickly removable top panel with dedicated cable routing ports. Furthermore, the enclosure facilitates toolless mounting of compatible power distribution units (PDUs) and cable managers, enhancing operational efficiency and reducing cable clutter in hot aisle/cold aisle configurations.
