Dear friend!
Take the OSN 9800 as an example:
The alarm can be repaired automatically, and the database auto-repair function is available in case of the alarm. If the alarm lasts for more than 2 hours, the auto-repair function fails. In this case, manually repair the database.
1. If this alarm is reported by both the active and standby boards and a warm reset can trigger protection switching, perform the following operations:
Warm reset the active board. The active/standby protection switching is triggered.
After the board starts up, preferentially perform manual switching. If manual switching fails, remove a board to trigger protection switching.
After the protection switching succeeds, warm reset the standby board.
2. If this alarm is reported by both the active and standby boards and a warm reset cannot trigger protection switching, perform the following operations:
Warm reset the active board.
When the active board starts up, warm reset the standby board.
For now, you'll need to observe for a while. If the alarm persists, repeat the preceding steps. If the alarm still persists, the board hardware may be faulty. In this case, you need to replace the board.
Thanks!
