Chapter 5: Chassis Management Module
Monitoring Functions
Used in conjunction with IPMI or the Web-based Management utility, the CMM module can
monitor and provide information on the hardware health of the blade modules and the system
as a whole. In addition to the monitoring functions, you can remotely power on, power off or
reboot a system.
Health information includes:
•
Temperature levels
•
Fan speeds
•
Voltage levels
•
Power status
Power Consumption Management
The CMM module 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.
Caution
: One CMM module must be running to control the power systems and prevent
overloading.
5.5 Reset Button
To reset, push the reset button for one minute until the blue led flashes (quick flash), then
release the button. The CMM is reset to default values:
IP Address -> 192.168.100.100
Gateway Address -> 0.0.0.0
Subnet Mask -> 255.255.255.0
