Cat5 Cable can save you from cabling disasters
Have you ever had a network cable go bad in a residence or business that is all but impossible to re-run, I have.. have you ever wondered just what you can do to resolve the issue while seeming like a magician to your customer.
say your green pair has a short or cut in it, but your blue, orange, and brown pair are still intact.
A simple rewire job on either end will solve the problem.
Punchdown the Cat5e Keystone jack with the brown pair where the green pair used to reside.
Back at the patch panel do the same.
If it's in a residence where they have put rj45 tips on the end of cable, simple re-tip it in the following configuration.
brown white/brown,orange white,blue,blue/white,orange,(do whatever with the green) doesn't matter.
