PCI Slot Connector

The Intel® SE7520AF2 Server Board enables 5 PCI expansion slots: Slot 1 (PCI-X 64/133), Slot
3 (PCI Exp x4), Slot 4 (PCI Exp x8), Slot 5 (PCI-X 64/133), Slot 6 (PCI-X 64/100). The PCI
Express* slots both are enabled with a x8 physical connector, although only Slot 4 has a x8
interface (Slot 3 has a x4 interface). All PCI slots support full-length full-height PCI add-in cards.
The tables below list the characteristics for the PCI slots and their pin-out.

The actual bus mode/speed is determined by capabilities of the adapter installed on that bus. PCI Express slots will
attempt to link train at their supported link and fall-back to a x1 link should the adapter not support the slot's maximun
link.
