A Switch Cannot Display Any Optical Module Information but Services Are Running Normally


  1. Check whether the optical modules are certified for Huawei Ethernet switches. If not, contact the supplier of the optical modules.
  2. Unplug and plug an optical module (if permitted), and check whether the optical module information can be displayed.
  3. If the problem persists, reboot or power off the switch (if permitted). If the problem is still unsolved after the reboot, check the software version running on the switch. If the switch is not running the latest software version, you are advised to upgrade the system software to the latest version.
    Services on the switch will be affected if you unplug and plug optical modules, reboot the switch, or upgrade the system software. Exercise caution when deciding to perform these operations.
  4. If all the preceding operations fail to rectify the fault, contact technical support personnel.
