11.6 Thermal Sensors
Proper thermal design is critical to the successful deployment of the MPCMM0002 CMM
chassis management module. In the event sufficient airflow is not provided, the CMM
has three levels of thermal protection:
1. A thermal sensor near the main processor (wired to ADM1026) and internal sensors
in ADM1026 are monitored by software, which then shuts down the CMM if
necessary.
2. A dedicated thermal circuit tells the power brick to shut off power to the rest of the
board if it detects an even higher temperature on the board.
3. Finally, the power converter shuts itself off if it gets too hot.
