Summary: An OTU board reports the IN_PWR_HIGH alarm indicating that a resistor fails in the Source optical module. Constantly reporting the alarm does not affect services, but is perceivable. Product Line: Transport Product Family: WDM Product Model: OptiX OSN 1800 OptiX OSN 6800 OptiX Metro 6100 [Problem Description] Trigger conditions: There is a low probability that an OTU board reports the IN_PWR_HIGH alarm after it has been running with an 80-km CWDM Source optical module for over a year. Symptom: An OTU board reports the IN_PWR_HIGH alarm while services are running properly. The maximum receive optical power is –7.x dBm, where x is a digit. Identification method: Verify that the following conditions are met: The OTU board is installed on the OptiX OSN 1800, OptiX Metro 6100, or OptiX OSN 6800. The model type of the optical module on the OTU board contains the “6128C-SL80” or “6128C-L80” field. The model type of the optical module can be determined by viewing the manufacturing information. Figure 1 shows the manufacturing information of an example optical module with the […]
