Supported Power Cords and Plugs Each power supply has a separate power cord. Standard power cords or jumper power cords are available for connection to a power distribution unit that has IEC 60320 C19 outlet receptacles. The standard power cords have an IEC C13 connector on the end that plugs into the switch. The optional jumper power cords, for use in cabinets, have an IEC C13 connector on the end that plugs into the switch and an IEC C14 connector on the end that plugs into an IEC C13 outlet receptacle.
