Table 5-1: Thermal Requirements - Kontron CP6924-1 User Manual

When developing applications using the CP6924, the system integrator must be aware of the overall system thermal
requirements. A system chassis must be provided which satisfy these requirements.
Measurements proofed that following conditions (maximum ambient temperature under maximum load) are possible while
all temperatures of on-board components stay below their critical thresholds.
For the CP6924-1-RC-C, the specified temperature refers to the mean temperature of both spacers (metal strips along the
PCB edge, bottom side) - these are the reference points according Vita 47.1.
The relation between the reference temperature value and the ambient temperature strongly depends on the construction
of the conduction cooled frame. Using a frame with good conduction cooling capabilities can decrease the difference
between reference and ambient temperature.

Note...
The holdup time of the real time clock (all CP6924 versions) is up to 6 days, under
moderate storage temperature conditions. It may decrease at lower or higher tem-
peratures (aberration is not qualified).
As Kontron assumes no responsibility for any damage to the CP6924 or
other equipment resulting from overheating any of the components, it
is highly recommended that system integrators as well as end users
confirm that the operational environment of the CP6924complies with
the thermal considerations set forth in this document.
