Front/Rear Ethernet and Transition Module Options Header (J30)

A 40-pin planar header allows for selecting P2 options. Jumpers installed across Row A pins 3-
10 and Row B pins 3-10 enable front Ethernet access. Jumpers installed across Row B pins 3-
10 and Row C pins 3-10 enable P2 (rear) Gigabit Ethernet. Only when front Ethernet is enabled
can the jumpers be installed across Row C and Row D on pins 1-10 to enable P2 (rear) PMC
I/O. Note that all jumpers must be installed across the same two rows (all between Row A and
Row B and/or Row C and Row D, or all between Row B and Row C).
The following illustration shows jumper setting options for J30. The factory default is shown
