20 System Controller R1.5, January 2021
5.1 Fan Speed and Trigger Bridge settings
Fan Speed and Trigger Bridge settings are managed by the CMM. To access these settings you
need access to the resp. CMM register via the system I²C bus (SMB).
With the SCHROFF embedded controller, the Fan Speed and Trigger Bridge settings of a
SCHROFF PXIe system can be displayed and managed by a dedicated tool called the

SCHROFF PXIe System Manager.
For third party system controllers contact the manufacturer for instructions to get access to
the system I²C bus and to read an write to the CMM register.
The CMM registers are decribed in the CMM User Guide 63972-391
By default the 3 trigger bus segments are isolated, the trigger bridges are disabled. To
enable the trigger bridges and set the direction of the routing, you have to access the
CMM‘s I²C register with the Schroff Embedded Controller or another appropriately
configured and programmed system controller.
