Hello,
Home is wired with Cat7 cable (S/FTP). In the server rack they are terminated with shielded keystones in a patch panel that has been bonded to PE on main earth terminal.
Should the cables that go to main electrical board be terminated same way there - shielded keystones on DIN rail? I assume DIN rail has to be isolated from rest of distributor metal, connected to PE and marked accordingly.
What worries me is that this creates a ground loop between server rack and electrical distribution - one path via PE from MET to patch panel, second path via ethernet cable shield. Is this how it's done with shielded ethernet and is OK? I dont see any other option, because even if ethernet socket was not grounded at one end, it could still get connected to PE through equipment if a shielded patch cable is used.
