Power Conservation and Power Budget
CMC performs power conservation when the user-configured maximum power limit is reached. When the demand for
power exceeds the user configured System Input Power Cap, CMC reduces power to servers in reverse-priority order to
free power for higher priority servers and other modules in the chassis.
If all or multiple slots in the chassis are configured with the same priority level, CMC decreases power to servers in
increasing slot number order. For example, if the servers in slots 1 and 2 have the same priority level, the power for the
server in slot 1 is decreased before that of the server in slot 2.
NOTE: You can assign a priority level to each server in the chassis assigning a number from 1 through 9 for each
server. The default priority level for all servers is 1. The lower the number, the higher the priority level.
The power budget is limited to a maximum of which ever set of three PSUs that is the weakest. If you attempt to set an
AC power budget value that exceeds the
budget is limited to 16685 Watts.
Maximum Power Conservation Mode
CMC performs maximum power conservation when:
• Maximum conservation mode is enabled
• An automated command line script, issued by a UPS device, enables maximum conservation mode.
In maximum power conservation mode, all servers start functioning at their minimum power levels, and all subsequent
server power allocation requests are denied. In this mode, the performance of powered on servers may be degraded.
Additional servers cannot be powered on, regardless of server priority.
