Representing Extension PDU Connections in OpenDCIM: Seeking Guidance on Upstream Linking

[alex001x]

Hello opendcim team
Is it possible to indicate to a secondary PDU (unmanaged) the link with the main port PDU instead of choosing the power panel to make the link between PDU 1 and pdu extension 1.1; 1.2; ...

In the list of power ports I added the rear sockets to make the link but the electrical panel does not show the estimated load. I think the power ports table is only one-way for linking devices, not for linking with upstream PDU

Electrical panel -> PDU1 (IBM manageable)->PDU 1.1 extension (unmanaged)->device(s)

If you have a solution to share, how to represent the connection of extension PDUs

Thanks for your help.
Alex.
