Acer AB460 F1 - Manual (Page 46)

2 Chassis Enclosure 26
Monitoring Functions
Used in conjunction with Acer Smart Blade Manager or Acer Smart
Blade Console, 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’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.
Note: Blade modules with onboard BMC in them provide
individual IPMI for each blade unit. It communicates with Acer
Smart Blade Manager or Acer Smart Blade Console.
