Parameter name
Parameter Meaning
Parameter 4
If the parameter is not 0x00, it means that the voltage on the corresponding single board is abnormal.
Parameter 5
- 0x01: Indicates that the output power of the corresponding single board power supply module is invalid.
- 0x02: Indicates that the corresponding single board detects an abnormal backup power supply.
- 0x04: Indicates that the corresponding single board is currently using the backup power.
- 0x05：Indicates that the corresponding single board power supply module has failed and the backup power supply module is being used.
Explanation:- When parameter 5 is 0x02, it is caused by the failure of the power module on the AUX board, please replace the AUX board, if there is still an alarm, then replace the single board that reported the alarm and check whether the slot is inverted.
- When parameter 5 is 0x04, the alarm can be solved by hard resetting the single board or unplugging the single board.
- If parameter 5 is other than 0x02 and 0x04 or parameter 4 is not 0x00, replace the board that reported the alarm.
