To increase the efficiency of the power supplies, you can monitor how much power the power supplies are using and shut down one side of a power supply unit.
Before You Begin
Log in to Oracle Integrated Lights Out Manager (ILOM). For instructions on how to log in to Oracle ILOM, see Launch and Log In to Oracle ILOM.
The default settings for the Light Load Efficiency Policies in Oracle ILOM include the following:
The Light Load Efficiency Mode is Disabled by default.
The Monitor Power Supply 0 Side 0 or Monitor Power Supply 0 Side 1 properties are Enabled by default.
The Monitor Power Supply 1 Side 0 or Monitor Power Supply 1 Side 1 properties are Enabled by default.
Ensure that you have Admin (a) role privileges in Oracle ILOM.
This procedure provides both web and command-line interface (CLI) instructions for the chassis monitoring module (CMM).
set /CMM/policy LIGHT_LOAD_EFFICIENCY_MODE=[ enabled|disabled ] MONITOR_PS n _SIDE n =[ enabled|disabled ]
Where n represents the power supply slot location (0 or 1) and side (0 or 1).
System Management Power Supply Policies Configurable from CMM, Oracle ILOM Configuration and Maintenance Guide for firmware version 3.1 or 3.2.
