Users Guide

When the Maximum Power Conservation Mode is enabled, the CMC sets the System Input Power Capacity to the maximum that the
chassis can handle. CMC does not allow power to exceed the highest capacity. However, PM3 handles all other power capacity limitations.
When PM3 management of power is disabled, the CMC reverts to the server priority settings before the external management was
enabled.
NOTE: When PM3 management is disabled, CMC does not revert to the earlier setting of the maximum chassis power. See the
CMC log for the earlier setting to manually restore the value.
Conguring Power Budget and Redundancy Using CMC Web
Interface
NOTE: To perform power management actions, you must have the Chassis Conguration Administrator privilege.
To congure power budget:
1 In the left pane, click Chassis Overview > Power > Conguration.
2 On the Budget/Redundancy Conguration page, select any or all of the following properties as appropriate. For information about
the eld descriptions, see the Online Help.
• Enable Server-Based Power Management
• System Input Power Cap
• Redundancy Policy
• Enable Dynamic Power Supply Engagement
• Disable Chassis Power Button
• Max Power Conservation Mode
• Enable Remote Power Logging
• Remote Power Logging Interval
3 Click Apply to save the changes.
Conguring Power Budget and Redundancy Using RACADM
NOTE
: To perform power management actions, you must have the Chassis Conguration 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 1 (Grid Redundancy), and 2 (Power Supply Redundancy). The default value is 2.
For example, the following command sets the redundancy policy to 1:
racadm config -g cfgChassisPower -o
cfgChassisRedundancyPolicy 1
• To set the power budget value, type:
racadm config -g cfgChassisPower -o
cfgChassisPowerCap <value>
where <value> is a number between 938 W — 4800 W, representing the maximum power limit in Watt. The default is 4800.
