Ethernet 2, PMC/SBC Mode, and P2 I/O Selection Headers
(J6, J7, J28, J32, J34, J97 – J110)
All of the headers described below are used in conjunction with each other
to select various modes of operation for 10/100BaseT Ethernet, PMC/SBC
mode, and P2 I/O mode.

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:

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.
