When power consumption exceeds the power threshold for Non-Aggressive
Mode and unable to recover within the time period specified in this parameter,
collects event log and sends an alert.
Allowable value (in seconds) depends on system. *6

*1: These values are reference purpose only. Each value might be different from the actual value which depends on your precise
server configuration.
*2: Technology that decreases frequency or duty cycle of clock, and suppresses power consumption.
*3: This item is not displayed when the system does not support this function.
*4: Can be specified only when Aggressive Mode is set to "Enable".
*5: AAA denotes "Standby power at minimum configuration" or "Power Threshold(Pn)".
*6: Can be specified only when Non-Aggressive Mode is set to "Enable".
*7: BBB denotes "Operating power at maximum configuration" or "Power Threshold(Pa)".
*8: Can be specified only when Boot Time Configuration is set to "Enable".
Note
•
The power value may not reach the threshold value. The power control feature
saves power consumption by lowering the clock speed of CPU/memory. If the
throttling value of CPU/memory reaches 100%, the power value cannot be
reduced no longer.
•
If the value specified for Power Threshold(Pa) for Aggressive Mode is lower than
the power required for system startup and the parameter "Shutdown System" is
enabled, the server might not start normally after shutdown.
When validating this setup, it is recommended to fully consider the value of
"Power Threshold (Pa)" to be specified.
