Setting Power Budget
NOTE: To perform power management actions, you must have Chassis
Configuration Administrator privilege.
Using the Web Interface
To set the power budget using the CMC Web interface:
1
Log in to the CMC Web interface.
2 Click Chassis Overview in the system tree.
The Chassis Health page is displayed.
3 Click the Power tab.
The
Power Monitoring Status page appears.
4 Click the Configuration subtab.
The
Budget/Redundancy Configuration page is displayed.
5 Type a budget value of up to 16685 watts in the System Input Power Cap
text
field.
NOTE: The power budget is limited to a maximum of which ever set of three
PSUs that is the weakest. If you attempt to set an AC power budget value that
exceeds this value, CMC displays a failure message.
NOTE: When value changes are specified in watts, the submitted value
exactly reflects the value that is applied. However, when the changes are
submitted in either of the BTU/h or percent units, the submitted value may not
exactly reflect the value that is applied. This is because these units are
converted to watts and then applied; and the conversion is susceptible to
some rounding error.
6 Click Apply to save your changes.
Using RACADM

racadm config -g cfgChassisPower -o
cfgChassisPowerCap <value>
where <value> is a number between 2715-16685 representing the maximum
power limit in watts. The default is 16685.
For example, the following command:
