7. Thermal Considerations
The following chapters provide system integrators with the necessary information to satisfy
thermal and airflow requirements when implementing AM4100 applications.
7.1 Thermal Monitoring
To ensure optimal operation and long-term reliability of the AM4100, all onboard components
must remain within the maximum temperature specifications. The most critical components on
the AM4100 are the processor and the memory. Operating the AM4100 above the maximum
operating limits will result in permanent damage to the board. To ensure functionality at the
maximum temperature, the Module Management Controller supports several temperature
monitoring and control features.
The AM4100 includes five temperature sensors that are accessible via the Module Manage-
ment Controller. They are distributed over the complete board to measure the onboard temper-
ature values.
Although temperature sensing information is made available to the MMC, the AM4100 itself
does not provide any active means of temperature regulation by default.
