I'm helping out a friend wire up his new office. He had CAT6 lines dropped in the appropriate locations (PC locations and back to the switch). At each PC location, he'll have a wall jack. We bought CAT6 keystone jacks and plates. At the switch side, he wants to forgo using a patch-panel for now.
He had his electrician terminate each of the lines (jacks at the walls and an RJ45 tip at the switch). Unfortunately, he didn't test as he went, and none of the connections work. To me, that means they were wired incorrectly at one or both ends. Help? I'm not sure he knows what he's doing, so I may take over.
If I want to use the T-568B standard for the office, do I just follow the T-568B process at each jack and for the tips of each at the switch or do I need to do crossover somewhere?
PC <-- patch cable --> []wall jack <--- cat6 in the wall --> {switch}
Thanks for any help!
Call the electrician and ask him to fix his work, I assume you paid him for services rendered. – Moab – 2016-01-12T18:06:01.837
yeah, that doesn't help if he doesn't know what he's doing. Hence the question. He has not been paid yet. – bcontento – 2016-01-12T18:10:24.577
Note that most modern Ethernet connectors auto-sense the send and receive lines, so crossed cables are unnecessary. – AFH – 2016-01-12T18:23:59.223
