The BLS power supplies are located in the platform racks. They occupy the center rack of a three-rack system in the North, Central and South sections of the platform.
Installation requires connecting AC power, water supply and return, External Interlock, Rack Monitor cables (4 total), Crate Selector module and DC output connections (8 total). These supplies require two people to lift them in place and a third person to help guide the cables in the back of the rack.
