4 Click the Configuration subtab.
The
Budget/Redundancy Configuration page appears.
5 Type a budget value of up to 11637 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
will exactly reflect what is actually applied. However, when the changes are
submitted in either of the BTU/h or percent units, the submitted value may
not exactly reflect what is actually 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
Open a serial/Telnet/SSH text console to CMC, log in, and type:
racadm config -g cfgChassisPower -o
cfgChassisPowerCap <value>
where <value> is a number between 2715–11637 representing the
maximum power limit in watts. The default is 11637.
For example, the following command:
racadm config -g cfgChassisPower -o
cfgChassisPowerCap 5400
sets the maximum power budget to 5400 watts.
NOTE: The power budget is limited to 11637 Watts. If you attempt to set an AC
power budget value that exceeds the power capacity of your chassis, CMC displays
a failure message.
