Power Management 321
5 Type a budget value of up to 11637 watts in the System Input Power Cap
text field.
NOTE: The power capacity of the chassis is limited to 11637 Watts. If you
attempt to set an AC power budget value that exceeds the power capacity of
your chassis, the 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 will be susceptible to
some rounding error.

Using RACADM
Open a serial/Telnet/SSH text console to the 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 capacity of the chassis is limited to 11637 Watts. If you attempt to
set an AC power budget value that exceeds the power capacity of your chassis, the
CMC displays a failure message.
