Configuring a power cap
To configure power capping, you can use the HPE Apollo Platform Manager, a rack level device that can
control power caps for all enclosures in the rack. For more information, see the
HPE Apollo Platform Manager
User Guide
(

) on the Hewlett Packard Enterprise website.
Setting the chassis power cap mode with HPE APM
Procedure
1.
Log in to APM.
a.
When the system boots, a Login prompt appears.
b.
At the prompt, enter
Administrator
.
2.
Before setting the power cap, enter the following command to review the power baseline:
>show power baseline
The information displayed provides the minimum cap value, the maximum cap value, and the chassis that
meet the requirements for power capping.
3.
To set the power cap for eligible chassis connected to the APM, enter the following command at the
prompt:
>SET POWER CAP<wattage>|NONE[zone_name]
The wattage value, if provided, represents the total wattage to be allocated among all the chassis that are
part of the baseline or partial baseline of a zone, if specified. This value is divided by the total maximum
wattage established by the baseline to calculate a percentage cap value. This percentage is then
multiplied against each chassis maximum wattage value to arrive at an appropriate cap value for that
individual chassis.
If
NONE
is specified instead of a cap wattage value, then APM removes all (or the specified zone) of the
power caps.
To remove baseline data from the EEPROM and to remove the power cap setting, enter the following
command:
>SET POWER BASELINE NONE
After this command is issued, the only way to re-establish a power baseline is to issue the
SET POWER
BASELINE
command. The system returns to the default power cap mode (mode 1).
