Power is normally supplied to the cpuModule through the top or bottom PCIe connectors (CN1 or CN2). If you
are placing the cpuModule onto a stack that has a PCIe/104 power supply, you do not need to make additional
connections to supply power.
Alternatively, if you are using the cpuModule without a PC/104 stack or with a stack that does not include a
power supply, refer to Auxiliary Power (CN3) on page 28 for an alternative method on how to power the
cpuModule.
