Configuring the power redundancy

To configure the power redundancy, use the information in this topic.

Note
  • AMD servers do not support configuring the power policy function.
  • When 2 power supply units are installed, the redundancy mode is set to Redundant (N+N). With this 2 Power supply units configuration, if one of the power supply units fail, AC lost or has been removed, it will report redundant lost event in XCC event log.
  • When only 1 power supply unit is installed after shipping, the redundancy mode will be automatically set to Non-redundant mode.

Available fields in the Power Redundancy section include the following:

  • Redundant (N+N): There are two or more independent power sources that are capable of supplying power to the system simultaneously. This means that if one or more power sources fails, the other source(s) can continue to supply power to the system without any interruption. N+N redundancy provides a high level of fault tolerance and ensures that the system remains operational even in the event of multiple failures.
    • Zero Output Mode: Once enabled under Redundant configuration, some PSUs will automatically enter into standby state under light load conditions. In this manner, the remaining PSU delivers the entire power load to increase efficiency.
  • Non-redundant mode: In this mode, the server is not guaranteed to remain operational if a power supply is lost. The server will throttle if a power supply fails in an attempt to remain running.
