The SR25UB premium SmartRack® Enclosure Cabinet is packed with features designed to simplify rack equipment installations and rack equipment maintenance: top and bottom cable routing ports, perforated door and side panels to promote efficient airflow, adjustable vertical mounting rails and more. And as part of the SmartRack family, the SR25UB is compatible with an extensive range of rack-mount accessories, enabling you to customize your solution to meet any requirement. The SR25UB ships fully assembled for quick installation.

The SR25UB has 25U of capacity and is compatible with all standard 19-inch rack equipment. The front and rear pairs of vertical rails feature square mounting holes and are numbered by rack space for easy reference. The rails are adjustable in quarter-inch increments to accommodate equipment depths from four to 37 inches. Adjustment is quick and convenient: simply unscrew the rails, slide them to the desired depth and restore the screws. The rails feature square mounting holes and are capable of supporting up to 3,000 pounds (1360.8 kilograms) of equipment with included installation hardware (2,250 pounds (1020.6 kilograms) rolling capacity).

With a locking, reversible front door and locking, removable side panels, SR25UB provides safe, secure installation for all equipment. This prevents unauthorized access to installed equipment while making it easy for authorized personnel to perform inspections, maintenance and equipment replacement. The enclosure meets all requirements toward PCI DSS compliance.

The top and bottom panels of the SR25UB are furnished with vents designed to help remove warm air from the enclosure and draw in cool air by convection. They also support installation of standard user-supplied case fans (SRFANROOF). The top and bottom panels are also provided with ports for cable routing.

To simplify deployment, the SR25UB comes with casters that enable it to be maneuvered into to desired location, and then secured in place by adjusting the unit’s levelers. Note: The casters are intended for minor position adjustments within the final installation area only and are not designed for moving the enclosure over long distances.

Ships fully assembled for rapid deployment and roll into place on heavy-duty pre-installed casters (casters are removable)
