Remote optical transceiver parameters exceed alarm threshold

0x2e31305e Remote optical transceiver parameters exceed alarm threshold

System generates 0x2e31305e Remote optical transceiver parameters exceed alarm threshold alarm. When the values of the parameters configured for the optical transceiver on the ONT side exceed the alarm thresholds.

Attribute:

Alarm ID Alarm Severity Alarm Type
0x2e31305e Minor Fault

Impact on the System:

The system cannot work normally, for example, the ONT goes online and offline abnormally and packets are lost.

Possible Causes:

  • The ONT’s optical transceiver is faulty.
  • The voltage is abnormal.
  • The current is abnormal.
  • The temperature is abnormal.
  • The alarm thresholds set in the system are improper.
  • The optical path is abnormal.
  • The ONU’s optical transceiver is faulty.

Procedure:

  1. Run the display ont optical-info command to query the transmit optical power, temperature, voltage,current of the optical transceiver, and CATV Rx-power on the ONT. Then, check whether the values of the preceding parameters are in the normal ranges.
    • If the values of the preceding parameters are in the normal ranges, go to 2.
    • If the values of the preceding parameters are not in the normal ranges, when the optical transceiver is swappable, replace the optical transceiver; when the optical transceiver is not swappable, replace the ONT. Go to 4.
  2. Run the display ont optical-alarm-profile command to query the upper limits and the lower limits of the optical parameters in the alarm profile. Then, check whether the values of the parameters (optical power, temperature, voltage,current, and CATV Rx-power) queried in step 1 are between the corresponding upper limits and lower limits.
    • If the values of the parameters queried in step 1 exceed the corresponding upper limits or lower limits, go to 3.
  3. Follow the steps below to rebind the optical parameters alarm profile.
    1. Run the undo ont optical-alarm-profile command to unbind the optical parameters alarm profile.
    2. Run the optical-alarm-profile modify command to modify the alarm thresholds defined in the optical parameters alarm profile to proper values.
    3. Run the ont optical-alarm-profile command to bind the ONT with a new optical parameters alarm profile. Go to 4.
  4. heck whether the clear alarm is generated.
