The PCIe* device isn't detected by the Intel® Server Board S2600CW when only CPU1 is installed.
Both CPU (Central Processing Unit) power connectors need to be connected in order for all the Peripheral Component Interconnect Express* (PCIe*) slots to work even if only one CPU is installed.
To fix this, make sure to connect the CPU2 power connector.
