How should I proceed ? Just continue to identify the devices on each set of cables?
I should note that of the three sets that were connected I have only rewired two so perhaps those intial expanders are on the set I didn't wire in.
As seen in the picture below there is a red fault light on and the rest of the system configured on network 1 has no power. The orange thing furthest to the left (pardon my lack of understanding) is running extremely hot
Help appreciated.
