Configuring and Managing Power
You can use the Web-based and RACADM interfaces to manage and
configure power controls on the CMC, as outlined in the following sections.
For detailed information on the various power management options, see
"Power Management" in the CMC User’s Guide.
Configuring Power Budget and Redundancy
The CMC’s power management service optimizes power consumption for the
entire chassis (the chassis, servers, I/O modules, iKVM, CMC, and PSUs) and
re-allocates power to different modules based on the demand.
NOTE: To perform power management actions, you must have Chassis Control
Administrator privileges.

Installing or Updating the CMC Firmware
NOTE: It is normal for some or all of the fan units to spin at 100 percent during CMC
or iDRAC firmware updates on a server.
Updating Firmware in a Redundant CMC Configuration
NOTE: In redundant CMC configuration, care must be taken to update CMC
firmware on both modules. Failure to do so may cause unexpected behavior during
a CMC failover or failback. Use the following procedure for redundant CMC
deployments.
