45U SmartRack Enclosure ships mounted on a special pallet that features additional reinforcement and shock-absorbing material. The pallet's protective cushion safeguards the enclosure and the precision components it contains during re-shipping. Reinforced pallets and reusable packaging provide the flexibility to fully configure rack enclosures in a centralized location and safely re-ship them to remote sites, saving significant service costs. They also allow the freedom to custom-configure enclosures with network and server hardware along with UPS systems, PDUs, KVM switches and a variety of other devices prior to final installation. At the desired location the SR45UBSP1 can be easily maneuvered with its preinstalled casters and can be secured by adjusting the preinstalled levelers. The SR45UBSP1 houses 3000lbs of standard 19-inch rack equipment in 45U. Its front and rear pairs of vertical rails have square mounting holes that are adjustable in quarter-inch increments from 4 to 37 inches. Adjustment is quick and an easy-view depth index ensures consistent rail placement without requiring time-consuming measurements. Each rack space within the enclosure is numbered for ready reference. Two of the adjustable vertical mounting rails support toolless button-mount 0U installation of up to four compatible PDUs and cable managers. This feature makes it easier to route cabling to rack equipment and reduces cord clutter. With its locking, reversible, removable front and rear doors, and locking, removable side panels, the SR45UBUSP1 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 SR45UBSP1 meets all requirements toward PCI DSS compliance.
