50 CMA24BT cpuModule BDM-610000087 Rev A
PCIe/104 Type 2 Compatibility
The PCIe/104 Type 2 connector is compatible with any PCI/104-Express or PCIe/104 peripheral module
that does not use the x16 Link. This includes any card that uses the PCIe x1 links, USB, or a power supply.
In addition, this connector can be used to add SATA devices to the system.
If a card is installed that is not compatible with the Type 2 connector, the CPU will keep the system in
soft-off, and the LED will be Cyan to indicate that there is a Bus Stacking Error.
