One embodiment includes an electronic assembly having a first printed
circuit board (PCB) and a second PCB. The second PCB has at least one
processor coupled to and disposed above the first PCB. A thermal
dissipation device is disposed above the second PCB, dissipates heat away
from the processor, and provides an airflow path. First and second power
systems are coupled to the second PCB and in a pathway of the airflow
path. The first and second power systems are redundant such that upon
failure of the first power system, the second power system can provide
power for both power systems.
