Impact on the System

The optical module may fail to work. Services may be interrupted on the port that has the optical module installed.

Possible Causes

Cause 1: The optical module is a non-Huawei-customized optical module. The error code is 136192.

Cause 2: The transmit optical power of the optical module was too high. The error code is 136193.

Cause 3: The transmit optical power of the optical module was too low. The error code is 136194.

Cause 4: The receive optical power of the optical module was too high. The error code is 136195.

Cause 5: The receive optical power of the optical module was too low. The error code is 136196.

Procedure

  • Cause 1: The optical module is a non-Huawei-customized optical module. The error code is 136192.
    1. If this optical module was early delivered from Huawei, run the transceiver phony-alarm-disable command to disable the alarm function for non-Huawei-customized optical modules.
    2. If this optical module is not delivered from Huawei or is not customized for Huawei, replace it with a Huawei-customized optical module.
  • Cause 2: The transmit optical power of the optical module was too high. The error code is 136193.
    1. Run the display transceiver slot slot-id verbose command in the system view to check whether the transmit power Tx Power of the optical module is within the allowed range.

      • If so, services are not affected. Collect alarms, logs, and configurations and contact technical support personnel.
      • If not, go to step 2.

    2. Check whether the transmit power upper threshold of the optical module is within the acceptable range.

      • If so, run the transceiver diagnosis threshold tx-power command to change the transmit power upper threshold of the optical module. The alarm handling ends.
      • If not, go to step 3.

    3. Use an optical attenuator to reduce the transmit power of the optical module to the acceptable range. Check whether the alarm is cleared.

      • If so, the alarm handling ends.
      • If not, go to step 4.

    4. Replace the optical module, and check whether the alarm is cleared.

      • If so, the alarm handling ends.
      • If not, collect alarms, logs, and configurations, and contact technical support personnel.

  • Cause 3: The transmit optical power of the optical module was too low. The error code is 136194.
    1. Run the display transceiver slot slot-id verbose command in the system view to check whether the transmit power Tx Power of the optical module is within the allowed range.

      • If so, services are not affected. Collect alarms, logs, and configurations and contact technical support personnel.
      • If not, go to step 2.

    2. Check whether the transmit power lower threshold of the optical module is within the acceptable range.

      • If so, run the transceiver diagnosis threshold tx-power command to change the transmit power lower threshold of the optical module. The alarm handling ends.
      • If not, go to step 3.

    3. Replace the optical module, and check whether the alarm is cleared.

      • If so, the alarm handling ends.
      • If not, collect alarms, logs, and configurations, and contact technical support personnel.

  • Cause 4: The receive optical power of the optical module was too high. The error code is 136195.
    1. Run the display transceiver slot slot-id verbose command in the system view to check whether the receive power Rx Power of the optical module is within the allowed range.

      • If so, collect alarms, logs, and configurations, and contact technical support personnel.
      • If not, go to step 2.

    2. Check whether the receive power of the optical module is within a usable range.

      • If so, run the transceiver diagnosis threshold rx-power command to change the receive power upper threshold of the optical module. The alarm handling ends.
      • If not, go to step 3.

    3. Check whether an alarm is generated for high transmit power on the peer optical module. If so, rectify the peer optical module fault first.
    4. Check whether the peer optical module and the local optical module are of the same type. If not, replace the local optical module with a new one to ensure they are of the same type.
    5. Add -5 dBm (recommended) attenuators to the optical module.
    6. If the problem persists after the preceding steps, collect alarms, logs, and configurations, and contact technical support personnel.
  • Cause 5: The receive optical power of the optical module was too low. The error code is 136196.
    1. Run the display transceiverslot slot-id verbose command in the system view to check whether the receive power Rx Power of the local interface is within the acceptable range.

      • If so, collect alarms, logs, and configurations, and contact technical support personnel.
      • If not, go to step 2.

    2. Check whether the receive power of the optical module is within a usable range.

      • If so, run the transceiver diagnosis threshold rx-power command to change the receive power lower threshold of the optical module. The alarm handling ends.
      • If not, go to step 3.

    3. Check whether the peer port is physically Up and whether there is no alarm indicating that the transmit power is too low.

      • If so, perform an external loopback test on the interface. If the interface is in Up state, perform loopback tests on the nodes along the transmission path to locate the failure point or link. Then check whether the alarm is cleared. If not, go to 4.
      • If not, go to step 4.

    4. Check whether the peer port is physically Down and a corresponding alarm is generated, rectify the fault on the peer port.

      • If so, repair the pee port. Check whether the alarm is cleared. If not, go to step 5.
      • If not, go to step 5.

    5. Test whether the fiber is working normally.

      • If so, replace the fiber and check whether the alarm is cleared. If not, go to step 6.
      • If not, go to step 6.

    6. Replace the optical module of the local port and check whether the alarm is cleared.

      • If so, the alarm handling ends.
      • If not, go to step 7.

    7. Collect alarms, logs, and configurations, and contact technical support personnel.
