Huijue Switch Optical Module Overheating

Home / Huijue Switch Optical Module Overheating

A Huawei S12708 switch experienced excessive fan spinning due to a faulty optical module. 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. We summarized the lessons learned and proposed preventative measures to ensure network. Heavy data traffic, poor heat dissipation, high ambient temperature and component aging easily overheat optical transceiver, resulting in signal degradation, higher bit error rates, shorter transmission distance and even module failure. Network outages can bring your ability to communicate and work to a halt, and your IT team will likely be frantically looking for a solution.
