Dear friend!
It cannot be directly determined that the board hardware is faulty. The other possible causes are as follows:
1. The board software works abnormally or the version does not match.
2. The hardware is in poor contact.
3. The subrack slot has bent pins.
4. The power supply is faulty.
5. Other alarms, such as BUS_ERR.
After other alarms and version matching problems are cleared, You are advised to perform a warm reset on the board, and then perform a cold reset on the board. Remove the board and install it in the subrack. Check whether bent pins exist. Check whether the power supply is stable. Install the faulty board in another slot and a new board in the faulty slot. Then, check whether the same alarm is generated. If the alarm persists on the board, the hardware may be faulty. In this case, replace the board.
