The overall power health is at least in Non-Critical state when the chassis is operating in 110V mode and the user has

not enabled the 110V operation. The "Warning" icon is displayed on the Web interface main page when in Non-Critical

state.

Mixed 110V and 220V operation is not supported. If CMC detects that both voltages are in use, then one voltage is

selected and those power supplies connected to the other voltage are powered off and marked as failed.

Server Performance Over Power Redundancy

When enabled, this option favors server performance and server powerup, over maintaining power redundancy. When

disabled, the system favors power redundancy over server performance. When disabled, then if the power 298

Managing and Monitoring Power supplies in the chassis do not provide sufficient power, both for redundancy, as well

as full performance, then to preserve redundancy, some servers may not be:

• Granted sufficient power for full performance

• Powered on

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 12th generation servers

• Server Priority of 12th generation 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 12th generation 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 12th generation 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.
