Each type of Ethernet switch comes with either one or two power cords depending on its needs. The power cords provided with the switches require PDUs with C13 IEC receptacles. HCP G11 servers come with two power cords each that also require PDUs with C13 IEC receptacles.
If your PDUs are not compatible with either of these types of power cords, you need to provide alternative power cords as applicable. The power cords you provide must have a C13 IEC plug at the end that connects to the server or switch.
