7.2
The baseboard provides one riser slot providing both PCI-X and PCI Express signals to a riser
card capable of supporting full-height add-in cards. The baseboard also provides one riser slot
providing PCI-X signals to a riser card capable of supporting low-profile add-in cards. The
following table shows the pinout for these riser slots.
7.2.1
The low-profile riser slot (J5F1) pin assignments are shown below. On a given riser card, the
PCI add-in slot closest to the baseboard will always have device ID 17. On a three-slot riser
card the middle PCI add-in slot (not supported on the Server Board SE7320VP2) will have
device ID 18, and the top slot (not supported on the Server Board SE7320VP2) will have device
ID 19. The interrupts on the PCI add-in slots should be rotated following the PCI bridge
specification 1.0. To prevent anyone from putting a PCI add-in card directly into the riser slot,
the connector has been pinned out so that Pin 1 is furthest from the board edge. Side B should
be closest to the memory DIMMs.
