Chapter 4: System Modules
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, via a SIMBL add-on card 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.
CMM Switches and Buttons
The various switches and buttons found on the CMM are described below.
USB Switch
Figure 4-6. USB Switch on Rear of CMM
The USB ports on the CMM can function in either 2.0 or 1.1 mode (the default is 1.1). A
switch located on the PCB at the back of the CMM module is used to change the USB
mode (see
Figure 4-6
).
NOTE:
Blade modules with a SIMBL add-on card installed in them provide
individual IPMI for each Blade unit. It communicates with the CMM and is
connected to the Gb Ethernet switch module for remote web or IPMI View
access.
WARNING:
One CMM module must be running to control the power systems
and prevent overloading.
