Power Management 281

Type a budget value of up to 7928 watts in the

System Input Power Cap

text field.

NOTE: The power budget is limited to a maximum of three PSUs out of a total

of six PSUs. If you attempt to set a AC power budget value that exceeds the

power capacity of your chassis, the CMC will display 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 2715–7928 representing the maximum

power limit in watts. The default is 7928.

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 a maximum of three PSUs out of a total of six

PSUs. If you attempt to set a AC power budget value that exceeds the power

capacity of your chassis, the CMC displays a failure message.
