Cause : Power unit setup comes when the required number of power units does not match the detected number of active power units. When replacing an enclosure size F module, this warning occurs if the power- specific data in the module power card does not match the rest of the drive.

  1. If the power card connection is lost, the unit also triggers this warning.
  2. Confirm that the spare part and its power card are the correct part number.
  3. Ensure that the 44-pin cables between the MDCIC and power cards are mounted properly.
