Pci-Express Slots - Seco Qseven CQ7-A30 User Manual

3.3.12 PCI-express slots

CQ7-A30 board offer a possibility of expansion through a standard PCI-e x16 card edge connector, type TE p/n 2-
1612163-4 or equivalent, with the pinout shown in the following table.
On this slot, are carried out the four PCI express lanes coming from Qseven
availability of all four PCI express lanes depends on the Qseven
Please check the User Manual of the Qseven
It is also recommended to check that User Manual to see if these PCI-express lanes can be used in a grouped configuration, i.e. if they can be used in PCI-e x4
mode, in 2 x PCI-e x2, in 1 x PCI- e x2 + 2 x PCI-e x1, or if they must be strictly used in single lane configuration (i.e., four independent PCI-e x1 lanes).
