This model is used to combine a TP link switch with a part of this (amazon) or this (aliexpress) 24 port patch panel.
After receiving the patch panel I noticed it consisted of three 8 port parts.
I already had the TP link switches and decided to combine the two in 1 model.
I also added a single set version. I have not tested this version myself…
The author marked this model as their own original creation.
