A data center, a rack information handling system (RIHS) delivery kit, and a method provide for removing an RIHS from and delivering an RIHS to a data center. The data center includes an enclosure having a raised floor and a lateral opening. The lateral opening has a bottom edge that is aligned with the raised floor in order to transfer a rack information handling system (RIHS) through the lateral opening for a selected one of: (i) removing the RIHSs from the raised floor; and (ii) delivering the RIHS to the raised floor. The data center includes a pallet interface coupled to or integrated into an exterior edge of the raised floor and vertically presented to abut and engage a lateral edge of a roll-off rack shock pallet that supports the RIHS during transport.
