As individual processor characteristics vary as well as the system environment of the CP6000,
the information contained in Figures 7-1 and 7-2 must be viewed as a guide and not as an
absolute specification. It is the responsibility of the system integrator to ensure that system
requirements are specified accordingly.
An airflow of 1.0 m/s is a typical value for a standard
Kontron
ASM rack (6U 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.
7.2.3
Peripherals
When determining the thermal requirements for a given application, peripherals to be used with
the CP6000 must also be considered. Devices such as hard disks, PMC modules, etc. which
are directly attached to the CP6000 must also be capable of being operated at the tempera-
tures foreseen for the application. It may very well be necessary to revise system requirements
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 CP6000 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 CP6000 complies with the thermal considerations set forth in
this document.
Note ...
If the CP6000 is ordered for extended temperature range (-40°C to +85°C),
some features are limited, for example, the memory runs only with DDR266
(PC2100). As this version comes with a larger heat sink than the standard ver-
sion, the mounted heat sink extends partly over the area where the HDD is
intended to be installed. For this reason, it is not possible to directly install a
2.5" HDD on this CP6000 version.
