Table 9-12. System Power Policy Configuration
Item Description
System Input
Power Cap
Displays the user configured maximum power consumption limit
for the entire system (chassis, CMC, servers, I/O modules,
power supply units, iKVM, and fans). CMC enforces this limit via
reduced server power allocations, or by powering off lower priority
server modules. The value for system input power cap is displayed
in watts, BTU/h and percent units.
If the chassis power consumption exceeds the System Input Power
Cap, then the performance of lower priority servers is reduced until
total power consumption falls below the cap.
In cases where the servers are set to the same priority, then the
selection of the server for power reduction, or power-off action, is
based on the server slot number order. For example, the server in
slot 1 is selected first and the server in slot 16 is selected last.
