298 Power Management
In maximum power conservation mode, all servers start functioning at their
minimum power levels, and all subsequent server power allocation requests
are denied. In this mode, the performance of powered on servers may be
degraded. Additional servers cannot be powered on, regardless of server
priority.
The system is restored to full performance when the user or an automated
command line script clears the maximum conservation mode.
Using the Web Interface
You can select or clear the Max Power Conservation mode using the GUI:
1
Click Chassis Overview in the system tree.
2 Click Power  Configuration .
3 Select the Max Power Conservation Mode box to enable maximum power
conservation and click
Apply .
4 Clear the Max Power Conservation Mode box to restore normal operation
and click
Apply .
Using RACADM
Open a serial/Telnet/SSH console to the CMC and log in.
• To enable the maximum power consumption mode, type:
racadm config -g cfgChassisPower -o
cfgChassisMaxPowerConservationMode 1
• To restore normal operation, type:
racadm config -g cfgChassisPower -o
cfgChassisMaxPowerConservationMode 0
110V PSUs Operation
Some PSUs support operation with 110V AC input. This input can exceed
what is allowed for the branch circuit. If any PSUs are connected to 110V AC,
the user needs to set the CMC for normal operation of the enclosure. If it is
not set and 110V PSUs are detected, all subsequent server power allocation
requests are denied. In this case, additional servers cannot be powered on,
regardless of their priority. You can set CMC to use 110 V PSUs using the
Web interface or RACADM.
