- Query the Optix OSN3500 POWER_ABNORMAL alarm parameter through the network management or the navigator command :alm-get-curdata, and according to the type of the specific single board reporting POWER_ABNORMAL, determine whether it is a POWER_ABNORMAL alarm reported by the line board/branch board/optical amplifier board.
- The meanings of the POWER_ABNORMAL alarm parameters are as follows. Parameter 4 and parameter 5 distinguish the failed power supply according to the bits respectively. 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
- 0x01: Indicates that the 48V voltage of the A-channel power board is bad.
- 0x0d：Indicates that the lightning protection voltage of A power board is bad.
- 0x11：Indicates that the 48V voltage of B road power board is bad.
- 0x12：Indicates that the lightning protection voltage of B road power board is bad.
- 0xff: indicates that the above query is normal.
Parameter 4
- 0x00: indicates undervoltage.
- 0x01: Indicates overvoltage.
- 0xff: Indicates that the above query is normal.
- Optix OSN3500 checks whether the external power supply to the PIU is normal, whether both PIU power supplies are flowing equally, and whether the voltages are equal.
- If the voltage is 0V, check whether the PDU air switch is off, if the air switch is off, it may be caused by a short circuit, you need to check whether there is a short circuit on the equipment for the -48V, and the air switch can only be opened after the short circuit is eliminated.
- If the external power supply is normal and there is still an alarm, then replace the PIU that reported the alarm.
- If the problem still can not be solved, the single master directly replace the main control board.
- For dual-master control, as long as one of the detected -48V is not normal, the alarm will be reported, regardless of whether the master control is the main or standby. Replacement of the main control before the need to observe the two main control board panel PWRA (corresponding to the indication of the A road -48V power supply abnormal) and PWRB (corresponding to the indication of the B road -48V power supply abnormality) indicator, PWRA or PWRB have a bright red light on the main control of the main control of the detection of anomalies abnormalities, it is to be replaced.
