pls what is the color code for connecting rg45, a pacth panel and a faceplate
Are you asking what color goes where from the twisted pair bundle to the rear of a patch panel? There should be a color code on the back to indicate which wire goes where. Typically there are two codes labeled A and B. These are not compatible, and you need to always use A or B to match up the connections. A quick google search for ethernet color code will reveal several well written guides for creating your own cables and how to properly attach cat 5/6 to a patch panel.
