Dell 2 manual Remote Logging, External Power Management

those power supplies connected to the other voltage level are turned off and indicated as not functioning.

Remote Logging

Power consumption can be reported to a remote syslog server. Total chassis power consumption, minimum, maximum, and average power consumption over a collection period can be logged. For more information about enabling this feature and configuring the collection or logging interval, see Managing and Monitoring Power.

External Power Management

CMC power management is optionally controlled by the OpenManage Power Center (OMPC). For more information, see the OMPC User’s Guide.

When external power management is enabled, OMPC manages:

•Server power of supported VRTX servers

•Server priority of supported VRTX servers

•System input power capacity

•Maximum power conservation mode

The CMC continues to maintain or manage:

•Redundancy policy

•Remote power logging

•Server performance over power redundancy

•Dynamic power supply engagement

OPMC then manages prioritization and power of supported VRTX server nodes in the chassis from the budget available after allocation of power to chassis infrastructure and prior generation server nodes. Remote power logging is unaffected by external power management.

After the Server Based Power Management Mode is enabled, the chassis is prepared for PM3 management. All supported VRTX server priorities are set to 1 (High). PM3 manages the server power and priorities directly. Since PM3 controls compatible server power allocations, CMC no longer controls the Maximum Power Conservation Mode. Hence, this selection is disabled.

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.

Configuring Power Budget and Redundancy Using CMC Web Interface

NOTE: To perform power management actions, you must have the Chassis Configuration Administrator privilege.
