HP Integrated Lights-Out 4 - Manual (Page 190)

During POST, the ROM runs two power tests that determine the peak and minimum observed
power values.
•
Use the Power Cap Thresholds as guidelines for configuring the Power Cap Value.
Maximum Power Cap—The maximum power available for the servers in a group. The
servers in a group must not exceed this value. ◦
◦ Minimum High-Performance Cap—The maximum power that the servers in a group use
in their current configuration. A power cap set to this value does not affect server
performance.
◦ Minimum Power Cap—The minimum power that the servers in a group use. A power cap
set to this value reduces the server power usage to the minimum, which results in server
performance degradation.
•
The Power Cap Value section allows you to configure the power capping settings. For
instructions, see
“Configuring Automatic Group Power Capping settings” (page 190) .
The Current State section shows the current power consumption.
•
Present Power Reading—The current power reading for all servers in a group.
•
Present Power Cap—The configured power cap for all servers in a group. This value is 0 if
the power cap is not configured.

All of the systems in the selected group will be affected by the changes you make on this page.
3. Select the Enable power capping check box.
4. Enter the Power Cap Value in watts, BTU/hr, or as a percentage.
The percentage is the difference between the maximum and minimum power values. The
power cap value cannot be set below the server minimum power value.
When values are displayed in watts, click Show values in BTU/hr to change the display to
BTU/hr. When values are displayed in BTU/hr, click Show values in Watts to change the
display to watts.
