I'm looking at cabling our house with Cat6A, & leaning towards using S/FTP.
If I use shielded cable is grounding necessary if;
Setup: Router -> PoE capable network switch -> computers/TV's/Cameras/etc.
-I'm ok with (some) interference.
-Using PoE PD, powered by PoE network switch.
-Network switch is metal & has its own earth (via power plug).
In cases of lightning:
-if lightning hits the area nearby or
-if lightning hits house directly
How then is earthing the shielded cable relevant?
Everything I've read about earthing/grounding shielded Ethernet mentions doing so for sake of tapering off interference & giving it some place to go.
I know if UTP is used I don't need to ground, but that's not my question. More interested in if S/FTP is used & grounding isn't done, I know there will be interference.
