Removing an AC PSU from an SCE


Remove an AC power supply unit (PSU) from a system compute enclosure (SCE) in any of the following scenarios:

  • The AC PSU has failed.
  • The AC PSU needs to be replaced with a new model.



When an SCE is configured with four PSUs, remove a PSU without powering off the SCE if the other two or three PSUs in the SCE are supplying power properly.

Observe PSU indicators to check the PSU status. For details about the indicators, see Indicators and Buttons.


No data preparation is required for this operation.
