5. Thermal Considerations
The following chapters provide system integrators with the necessary information to satisfy thermal and air-
flow requirements when implementing AT8404 applications.
5.1 Thermal Monitoring
To ensure optimal operation and long-term reliability of the AT8404, all onboard components must remain
within the maximum temperature specifications. The most critical components on the AT8404 are the Unit
Computer and the Ethernet Switch. Additional sensors keep track of the inlet and outlet temperatures of the
AMC area and the rear part of the board.
Operating the AT8404 or the AMCs in the AT8404 above the maximum operating limits may result in perma-
nent damage to the board. To ensure functionality at the maximum temperature, the IPMC supports temper-
ature monitoring features. Although temperature sensing information is made available to the IPMC, the
AT8404 itself does not provide any active means of temperature regulation.
