UTP Cable Wiring

100BASE-TX unshielded twisted-pair cables can be wired as "Straight- Through" or, in some cases, "Cross-Over" depending on the application. For workstations connected to a hub, use "Straight-Through' wiring illustrated below in Table B-2. In some instances (e.g. cascading from one hub to another), you may use "Cross-Over" wiring illustrated below in Table B-3.

"Straight-Through" Cable Wiring

Pin Number		Pin Number
1	(TRX +)	1	(TRX +)
2	(TRX -)	2	(TRX -)
3	(RCV +)	3	(RCV +)
6	(RCV -)	6	(RCV -)
4, 5, 7, 8		Not Used
