The SR45UBDPWD is a deeper and wider version of our standard 45U SmartRack® cabinet. This enclosure is 1143 millimeters deep (45 inches) compared to the standard 1050 millimeters. This extra depth allows for high-density equipment installations. It allows extra space for moving the cable management back, as well as providing space for mounted equipment that has hot-swap, removable power supplies out the back of the enclosure. It is also 750 millimeters wide (30 inches) compared to the standard 600 millimeters. This extra width allows for high-density equipment installations. It allows cable management and PDU mounting off to the sides of the rack in order to keep these items out of the airflow for proper cooling.The SR45UBDPWD features a massive front-to-rear ventilation capacity that meets or exceeds server manufacturer requirements. Its integrated baying tabs make it easy to combine multiple enclosures in rows for data center applications. This enclosure is also compatible with hot-aisle/cold-aisle configurations.With its locking, reversible, removable front and rear doors and locking, removable side panels, the SR45UBDPWD provides ultimate equipment safety. The side panels are half size for ease of removal and reinstallation. The split rear door design allows the enclosure to be placed closer to a wall. The SR45UBDPWD meets all requirements toward PCI DSS compliance.The top panel of the SR45UBDPWD is vented to help remove warm air from the enclosure and draw in cool air by convection. The top panel includes ports for cable routing and can be quickly removed without tools. To facilitate cable access, the SR45UBDPWD is open-bottom.All components of the SR45UBDPWD are grounded to the enclosure frame. Front and rear threaded grounding points are provided for connection to the facility earth ground. The removable front and rear doors feature quick-release ground wires.It houses 3,000 pounds (1360.8 kilograms) of standard 19-inch rack equipment in 45U. To simplify deployment, the SR45UBDPWD comes with preinstalled casters that enable it to be easily maneuvered into the desired location, where it can be secured by adjusting the preinstalled levelers. Note: The casters are intended for minor position adjustments and are not designed for moving the enclosure over long distances.
