  1. After the package loading is completed, you can click a menu option of the DC tool to check for all weak mapping boards.
  2. On the displayed window, select a specific weak mapping board, right-click, and choose to upgrade the board software.
  3. After all weak mapping boards' software is upgraded, the alarm may clear.
  4. For detailed operations, refer to the specific product's upgrade guide.
  5. Check whether the alarm clears. If the alarm persists, contact Huawei engineers to handle the alarm.
