Ethernet 2, PMC/SBC Mode, and P2 I/O Selection Headers (J6, J7, J28, J32, J34, J97 – J110) Connector Pin

5.3.1.1Ethernet

Four 3-pin 2 mm planar headers and four 2-pin 2 mm planar headers are for 10/100/BaseT Ethernet 2 selection. Ethernet 1 is the Gigabit Ethernet port and is front panel only. The pin assignments for these headers are as follows:

Table 5-20 Ethernet 2 Selection Headers (J6, J7, J100, J101) Pin Assignments

10/100 Ethernet Receive Pairs		10/100 Ethernet Transmit Pairs
J6		J7
Pin	Signal	Signal	Pin
1	FP_RX–	FP_TX+	1
2	RX–	TX+	2
3	P2_RX–	P2_TX+	3
J100		J101
1	FP_RX+	FP_TX–	4
2	RX+	TX–	5
3	P2_RX+	P2_TX–	6

For rear P2 Ethernet, install jumpers across pins 2-3 on all four headers (J6, J7, J100 and J101). For front-panel Ethernet, install jumpers across pins 1-2 on all four headers.

If the rear P2 Ethernet is selected by jumpers J6, J7, J100 and J101, the Ethernet signals also connect to PMC 1 user I/O connector J14. If a PMC card is plugged into PMC 1, there may be a conflict between the I/O from the PMC card and the rear Ethernet signals. This conflict does not occur with the IPMC761 or IPMC712 modules.

Table 5-21 Ethernet 2 Selection Headers (J34, J97, J98, J99) Pin Assignments

Pin	Signal	Pin	Signal
J34		J97
1	PMC1_IO(7)	1	PMC1_IO (5)
2	P2_TX+	2	P2_TX-
J98		J99
1	PMC1_IO(3)	1	PMC1_IO (1)
2	P2_RX+	2	P2_RX-

For rear P2 Ethernet, install jumpers on all four headers (J34, J97, J98 and J99) when in SBC/IPMC761 mode. No jumpers are installed for front-panel Ethernet.
