Achieving a shielded grounded network
My objective is to achieve a shielded network that eliminates troublesome noise. I understand I need to use shielded cables, shielded and grounded patch panel, shielded patch cables but I am confused as to which switch will allow me to achieve my objective. Perhaps using the TL-SG105 which is metal encased and connects electrically via its AC power adapter will do? I am confussed because I read: (1) switch should be grounded; (2) then again I read, that grounding of a switch is not necessary?
Thank you for offering clarification and direction.
