Table 8-8. System Power Policy Configuration
Item Description
System Max AC
Power Limit
Displays the user-defined maximum power consumption limit for
the entire system (chassis, CMCs, servers, I/O modules, PSUs,
iKVM, and fans). The CMC enforces this limit by throttling (if
enabled) or by powering off lower priority servers (if throttling is not
enabled).
System AC
Power Warning
Threshold
Displays the maximum amount of power, in watts, beyond which
the CMC takes action to reduce power consumption.
If Server Power Throttling Enabled is checked, and the chassis
power consumption exceeds the power warning threshold, then the
performance of lower priority servers is reduced until total power
consumption falls below the threshold.
If Server Power Throttling Enabled is not checked, servers with
lower priority may be powered off until total power consumption
falls below the threshold.
Server Power
Throttling
Enabled
Enables the user to configure the system to compromise server
performance to conserve power if the available power is reduced.
