HP ProLiant SL4500 Series Setup and Installation Guide

Cabling and powering up the chassis 46
2.
Log in to the node, and then run the PPIC utility.
3. To set the power capacity mode, perform one of the following steps:
o To set mode 0, 1, and 2, enter the following command at the prompt:
-s -mmode
The following example sets the power capacity to mode 0:
-s -m0
o To set mode 3, enter the following command at the prompt:
-s -mmode -lpower
The following example sets the power capacity to mode 3 with a 1500W maximum power limit:
-s -m3 -l1500
Power capping modes (on page 45) show the valid values for mode. Power is required when setting Power
Control Configuration to User Configurable.
For more information, see the HP ProLiant Power Interface Control (PPIC) Utility User Guide on the HP website
(http://www.hp.com/support/PPIC_UG_en).
Setting the chassis power cap mode with SL-APM
1. Log in to SL-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 SL-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 SL-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).
