Power Conservation and Power Budget

CMC conserves power 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 the order of increasing slot number. 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 whichever set of two PSUs that is the weakest. If you attempt to set an AC power budget value that exceeds the System Input Power Cap value, CMC displays a message. The power budget is limited to 4800W.
