Hello,


  • Proactive Maintiance List for OLT (MA5800V100R017C00)

    This section describes the information required in network maintenance, including maintenance record and field maintenance.

    Overview
    This topic describes the basic principles of the routine maintenance, suggestions on the maintenance of the third-party devices, and method of obtaining the technical support from Huawei.
    Checking the Grounding of the Device
    It is recommended that you check whether the ground cable is properly installed and whether the ground resistance complies with the relevant standard once every three months. This operation ensures the reliable running of the device and avoids the potential security risks that may exist in the system.
    Checking the Sensor
    It is recommended that you check whether the hardware of sensors is normal once every three months. This operation ensures that the sensors can report environment alarms normally and correctly and facilitates monitoring of the running environment of NEs according to the reported environment alarms.
    Checking the Hardware Status of Fans
    It is recommended that you check the hardware status of fans once every three months. This operation ensures that the system can work under proper temperature.
    Cleaning the Air Filter of the MA5800 Cabinet
    It is recommended that you clean the air filters of the cabinet once every year. This operation ensures that the heat dissipation system works properly.
    Checking the Cabinet Appearance of the MA5800 Cabinet
    It is recommended that you should check the cabinet Appearance once every year. This operation ensures that the cabinet can work normally and stably.
    Device Routine Maintenance Record
    According to different maintenance tasks, multiple maintenance tables are provided. Maintenance personnel can maintain the device on the basis of the contents in these tables and can record the maintenance information.

Dear friends!

Are you talking about PNM?


PNM relies on pre-equalization coefficients. Specifically, the CMTS monitors the pre-equalization coefficient of each cable modem (CM) on the hybrid fiber coaxial (HFC). By analyzing these pre-equalization coefficients, the CMTS identifies slight line running indicator changes and detects a latent fault. Based on the analysis results and CM topology, the maintenance personnel locate and rectify the fault before the fault adversely affects user services.


A pre-equalization coefficient is used to compensate line distortion caused by mismatched impedance, an insecurely connected connector, or a damaged cable. Therefore, line fault information can be identified in a pre-equalization coefficient. A pre-equalization coefficient reflects a fault location while providing the fault type and severity.
