 cabling ?
Dear sirs:
My question involves cabling a network. When would you use a cross-over patch cable in regards to a straight thru patch cable ?
I find it very confusing, is it determined by the type of cabling that was performed from the patch panel to the wall plate ?
If you ran a 568A or 568B from the wall plate to the workstation, would that constitute a crossover patch cable from the patch panel to the hub ?
If you could please clear this issue up for me, it would be greatly appreciated.

Thank you

Dear Bob ,

The only need for a cross-over cable is for connection between two hubs or directly between two PCs. Also, the hub connection needs a cross-over cable only if you are cascading using regular ports (ones you'd usually connect PCs to). Most hub/switch models nowadays have a special "uplink" port that you can make a cross-over with a simple touch of a button, or even auto-sensing!
