Power Consumption Management
The CMM module’s firmware can also control all power on/off activity in the whole blade
system. This is done by using the Power button, onboard BMC or from any other use of
remote management software.
Once a blade module is installed in the enclosure the installed CMM immediately
receives information on the rated Max Power Consumption value of the new blade
module. The CMM then calculates whether there is enough power for this new blade
module by comparing the Max Power Consumption value of the new blade module with
the calculated Remaining Power value of the system.
If there is enough power, the CMM will power on the blade. However if there is not
enough power in the blade system, then the new blade module is not powered on and
the front panel LED on the enclosure will blink.
After the blade is powered on, the CMM then collects the actual power consumption of
this individual blade and updates the calculated Remaining Power value for the system.
The CMM also reserves power for all the networking and chassis management modules
installed on the system.
WARNING: One CMM module must be running to control the power systems and prevent
overloading.
