4.5.2 External Cooling Management
If you decide not to rely on the ATCA-M100/MF105/SAM1410 cooling management, you can
switch the ATCA-M100/MF105/SAM1410 cooling management off. Then you have the
following two options to control the fan speed and thus perform cooling management:
 Use a Linux example program
 Access HPI controls
4.5.2.1 Toggling Between External and Internal Cooling Management
Although we strongly recommend to rely on the ATCA-M100/MF105/SAM1410 shelf
management software for cooling management, in some situations you may want to control
the fan speed manually or you may want to use external shelf management software. For this
purpose, the internal cooling management can be switched off.
If the internal cooling management is switched off, the ATCA-M100/MF105/SAM1410 cooling
management software still monitors temperature sensors and handles all events, but no set
operations are actually executed. If the internal cooling management is switched on again, the
cooling management software executes all necessary cooling actions according to the current
state of the system.
In order to switch on/off the internal cooling management, use the Linux example program
hpicooling
which is delivered with the ATCA-M100/MF105/SAM1410 software. The usage
of the example program is as follows.
Description
This service allows you to switch on/off the internal cooling management.
Damage of Shelf and Blades/FRUs
The cooling management as performed by the ATCA-M100/MF105/SAM1410 provides
optimized cooling for the shelf and all blades/FRUs in it. It has been adapted and optimized
for the shelf. Performing cooling management manually or via (inadequate) external shelf
management software may lead to overheating and thus damage of the shelf and
blades/FRUs in it.
Perform cooling management only via the ATCA-M100/MF105/SAM1410 software.
