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 on enabling this feature and configuring the collection and logging interval, see the
Executing Power Control Operations section.
External Power Management
CMC Power management is optionally controlled by the Dell OpenManage Power Center. For more
information, see the Dell OpenManage Power Center User’s Guide.
When external power management is enabled, Dell OpenManage Power Center manages:
• Server Power of supported M1000e servers
• Server Priority of supported M1000e 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
• Server Power of 11th generation and earlier servers
Dell OpenManage Power Center then manages prioritization and power of supported M1000e servers
and later blade servers in the chassis from the budget available after allocation of power to chassis
infrastructure and prior generation blade servers. Remote power logging is unaffected by external power
management.
After the Server Based Power Management Mode is enabled, the chassis is prepared for Dell
OpenManage Power Center management. All supported M1000e servers and later server priorities are
set to 1 (High). Dell OpenManage Power Center manages the server power and priorities directly. Since
Dell OpenManage Power Center 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, Dell OpenManage Power Center handles all other power capacity limitations.
When Dell OpenManage Power Center management of power is disabled, the CMC reverts to the server
priority settings before the external management was enabled.
NOTE: When Dell OpenManage Power Center 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.
