The AC and DC power supplies support two ranges of voltages: low line (90V, 110/120V, 132V) and high line (180V, 200/240V, 305V). Depending on the input voltage, the power supply will support 1800W (for low line) and 3600W (for high line). The input voltage range determines the number of power supplies needed for the chassis. A chassis with low line input voltage requires a minimum of eight power supplies while a chassis with high line input voltage requires a minimum of four power supplies.
