PSU Removals With Degraded or No Redundancy Policy

CMC may begin conserving power when you remove a PSU or a PSU AC cable. 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 evaluates power needs again when the second PSU is removed to determine the firmware response. If power requirements are still not met, CMC may turn off the lower priority servers.

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