Impact on the System

System software upgrade failed.

Possible Causes

Cause 1:

LPUs fail to register.

Cause 2:

The new system software cannot start and the system rolls back to the previous version.


  1. After this alarm is displayed, by default, the system automatically rolls back to the previous system version. Run the display device command to check whether LPUs can register successfully.

    • If so, go to step 2.
    • If an LPU fails to register, the LPU hardware is faulty. Replace this LPU.

  2. Check whether the current version supports these LPUs.

    • If so, go to step 3.
    • If not, go to step 4.

  3. Run the reboot fast command to upgrade the CSS after a fast restart.
  4. Remove or replace the unsupported LPUs and then upgrade the CSS.
