Gigabit over Copper External Crossover Pinouts

When a crossover function is not provided by either the adapter or hub or switch, you must implement it through the twisted-pair media using the physical pinouts shown in Table C-12.

Table C-12

Gigabit over Copper Crossover Pinouts

Pin	Function	Color Match	Function	Pin
1	BI_DA+	White/Orange	BI_DB+	3
2	BI_DA-	Orange/White	BI_DB-	6
3	BI_DB+	White/Green	BI_DA+	1
4	BI_DC+	Blue/White	BI_DD+	7
5	BI_DC-	White/Blue	BI_DD-	8
6	BI_DB-	Green/White	BI_DA-	2
7	BI_DD+	White/Brown	BI_DC+	4
8	BI_DD-	Brown/White	BI_DC-	5

Figure C-4 shows the correct Gigabit over copper wiring to be used when the crossover function is implemented externally (in the twisted-pair cabling).
