need to know if the 1200W power supply (NC55-1200W-ACFW) uses a male C16 plug (with the locking lug) or a male C14 plug. We use standard C13 female / C14 male cables into the PDU, but I can't use those same cables if the power supply for the 5500 uses a C16 plug. There is no mention in any of the specs.
