If the fault is caused by incorrect configuration or networking environment, change the configuration or networking environment. Check whether the optical modules are Huawei-certified ones. If not, contact the supplier. If the optical module is installed on a GE port, run the display interface GigabitEthernet x/x/x command to check information about the port, including the rate and wavelength. The problem isn't necessarily the repair, it's the reliability of the device after. If that burnt out, there's a high likelihood that you will find it is not the root cause. I wouldn't use the device for. After opening the notebook my first step was disconnecting the battery power cable. While doing it, I've accidentally dropped the metal part that hold the power cable in the motherboard, while the power cable was still plugged. We summarized the lessons learned and proposed preventative measures to ensure network. The arg2 optical module temperature (arg4 degrees C) exceeds the overtemperature threshold (arg5 degrees C).
