- Query the POWER_ABNORMAL alarm parameter through the network management or the navigator command :alm-get-curdata, and according to the type of the specific veneer reporting POWER_ABNORMAL, determine whether it is a POWER_ABNORMAL alarm reported by the master board.
- The meanings of the POWER_ABNORMAL alarm parameters are as follows. Parameter 1 and parameter 4 distinguish the failed power supply according to the bits. A bit of 1 indicates that the alarm exists, and a bit of 0 indicates that the alarm does not exist.
Parameter Name
Parameter Meaning
Parameter 1
- 0x02: Indicates that the 5V voltage of this board is bad.
- 0x03：Indicates that the 3.6V voltage of this board is bad.
- 0x04：Indicates that the 3.3V voltage of this board is bad.
- 0x05：Indicates that the 3V backup voltage of this board is bad.
- 0x06：Indicates that the 3V voltage of AUX on this board is bad.
- 0x07：Indicates that the 2.5V voltage of this board is bad.
- 0x08：Indicates that the 1.8V voltage of this board is bad.
- 0x0a：Indicates that the 1.5V voltage of this board is bad.
- 0x0e：Indicates that the voltage of V33Bakin on this board is bad.
- 0xff: indicates that the above query is normal.
Explanation:- The alarms of 0x05, 0x06, 0x0e are caused by the failure of the power module on the AUX board, then replace the AUX veneer first, and if there are still alarms, then replace the main control board and check if the main control slot is backward pinned.
- If there are still alarms, then replace the main control board and check whether the slot of the main control is pinned backwards.
Parameter 4
- 0x00: Indicates undervoltage.
- 0x01: Indicates overvoltage.
- 0xff: Indicates that the above query is normal.
