Table 1-11. 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.
