An airflow of 1.0 m/s is a typical value for a standard
Kontron
ASM rack (3U CompactPCI rack
with a 1U cooling fan tray). Newer ASMs from
Kontron
will have an airspeed of 2.0 m/s or more.
For other racks or housings the available airflow will differ. The maximum ambient operating
temperature must be recalculated and/or measured for such environments. For the calculation
of the maximum ambient operating temperature, the processor junction temperature must
never exceed the specified limit for the involved processor type.

Peripherals
When determining the thermal requirements for a given application, peripherals to be used with
the CP307 must also be considered. Devices such as hard disks, extension modules, etc.
which are directly attached to the CP307 must also be capable of being operated at the tem-
peratures foreseen for the application. It may very well be necessary to revise system require-
ments to comply with operational environment conditions. In most cases, this will lead to a
reduction in the maximum allowable ambient operating temperature or even require active
cooling of the operating environment.
Warning!
As Kontron assumes no responsibility for any damage to the CP307 or other
equipment resulting from overheating of the CPU, it is highly recommended
that system integrators as well as end users confirm that the operational envi-
ronment of the CP307 complies with the thermal considerations set forth in
this document.
