You appear to have a device which can supply power to 48 RJ-45 connectors on the front panel? Which probably maps to 48 ports of a Ethernet switch. How do i use these properties described here to say that eth42 connects to port 42 of the PSE? > > + $ref: /schemas/types.yaml#/definitions/uint32-matrix > > + minItems: 1 > > + maxItems: 48 > > + items: > > + items: > > + - description: Logical port number > > + minimum: 0 > > + maximum: 47 > > + - description: Physical port number A (0xff for undefined) > > + oneOf: > > + - minimum: 0 > > + maximum: 95 > > + - const: 0xff > > + - description: Physical port number B (0xff for undefined) It would be good to explain what Port A and B are. It might be obvious to somebody who knows PSE, but i have no idea... Andrew
