Configuring Power Budget and Redundancy
You can configure the power budget, redundancy, and dynamic power of the entire chassis (chassis,
servers, I/O module, CMC, PCIe, and chassis infrastructure). The power management service optimizes
power consumption and reallocates power to different modules on the basis of requirement.
You can configure the following:
• System Input Power Cap
• Redundancy Policy
• Disable Chassis Power Button
• Max Power Conservation Mode
• Remote Power Logging
• Remote Power Logging Interval
Power Conservation and Power Budget
If the power usage exceeds the System Input Power Cap, the power supplied to the servers by the PSU is
reduced to maintain the nominal level.
Configuring Power Budget and Redundancy Using CMC Web Interface

To configure power budget:
1. In the left pane, click Chassis Overview → Power → Configuration.
2. On the Budget/Redundancy Configuration page, select any or all of the following properties as
appropriate. For information about the field descriptions, see the Online Help.
• Redundancy Policy

3. Click Apply to save the changes.
Configuring Power Budget and Redundancy Using RACADM
NOTE: To perform power management actions, you must have the Chassis Configuration
Administrator privilege.
To enable and set the redundancy policy:
1. Open a serial/Telnet/SSH text console to CMC and log in.
2. Set properties as needed:
• To select a redundancy policy, type:
racadm config -g cfgChassisPower -o
cfgChassisRedundancyPolicy <value>
where <value> is 0 (No Redundancy), 1 (Grid Redundancy), and 3 (Redundancy Alerting Only). The
default value is 3.
