Power Supply for Power Panel

[nqvan]

Hi all,

In my DC, the SLD for electric system is: UPS -> M.PDU -> PDF -> PDU.
With netbox structure and my idea, PDF is power panel and PDU is power feed. But I want to manage the entire power supply diagram from UPS to PDU at the rack. I plan to create UPS as a device, M.PDU cabinet as a device. UPS will have a power outlet connected to the power port of M.PDU.
However, I cannot supply power from M.PDU cabinets to power panels which are PDF cabinets. In this case, how can I trace the diagram from UPS to the device in the rack through M.PDU cabinets, PDF
