The SR48UBDPWD is a deeper and wider version of our standard 48U SmartRack cabinet. This enclosure is 1143mm deep (45") compared to the standard 1050mm deep. 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 750mm wide (30") compared to the standard 600mm. 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 SR48UBDPWD 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 SR48UBDPWD 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 SR48UBDPWD meets all requirements toward PCI DSS compliance. The top panel of the SR48UBDPWD 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 SR48UBDPWD is open-bottom. All components of the SR48UBDPWD 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 3,500 lb (1588 kg) of standard 19" rack equipment in 48U. To simplify deployment, the SR48UBDPWD 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.
