BDM-610000087 Rev A Chapter 3: Connecting the cpuModule 51
PCIe Link Configuration
This cpuModule supports a total of four PCIe x1 links for system expansion, all of which are on the
bottom-side PCIe/104 connector, CN2 . Three of the links on CN2 are connected directly to the chipset. The
fourth link is connected through a PCIe packet switch, which shares the bandwidth of a single x1 link back
to the chipset with the onboard PCIe-to-PCI bridge and the gigabit Ethernet controller. Table 25 below
shows the configuration of the PCIe x1 links on CN1 and CN2.
