This SmartRack® 18U Mid-Depth Rack 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. The SR18UB ships fully assembled for quick installation.

The SR18UB is compatible with all standard 19-inch rack equipment and features front and rear pairs of vertical rails with square mounting holes. The rails are adjustable in quarter-inch increments to accommodate equipment depths from three to 32.5 inches, ideal for standard server installation. The rails feature square mounting holes and are capable of supporting up to 1,000 pounds (453.6 kilograms) of equipment with included installation hardware. Each rack space within the enclosure is numbered for easy reference.

With locking, reversible front/rear doors and locking, removable side panels, the SR18UB 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 SR18UB 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 (including SRFANWM, sold separately). The top and bottom panels are also provided with ports for cable routing.

To simplify deployment, the SR18UB comes with an accessory caster kit consisting of four casters and all required installation hardware. With casters installed, the SR18UB can easily 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.
