Redundancy regained The power supplies are redundant.
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 based on the 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
• Disable AC Power Recovery
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
NOTE: To perform power management actions, you must have the Chassis Configuration Administrator privilege.
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
• Disable Chassis Power Button
• Max Power Conservation Mode
3. Click Apply to save the changes.
