Power Management After Removing PSU

CMC may begin conserving power when you remove a PSU or a PSU AC cord. CMC decreases power to the lower priority servers until power allocation is supported by the remaining PSUs in the chassis. If you remove more than one PSU, CMC again evaluates the power requirements when the second PSU is removed to determine the firmware response. If power requirements are still not met, CMC may turn off the low-priority servers.

Limits
  • CMC does not support automated power-down of a low-priority server to allow turning-on of a higher priority server; however, you can perform user-initiated turn-offs.
  • Changes to the PSU redundancy policy are limited by the number of PSUs in the chassis. You can select any of the two PSU redundancy configuration settings listed in Default Redundancy Configuration .
