If you are a maintenance engineer, read the following precautions before doing your work:

  • Confirm whether the fault is an emergency fault. If it is an emergency fault, recover the faulty module by using the pre-defined troubleshooting methods immediately, and then restore services.

  • Strictly conform to operation rules and industrial safety standards, ensuring human and device safety.

  • Wear the ESD wrist strap when touching device components.

  • Record original information about the problems occurring during troubleshooting.

  • Record all the operations you have performed, especially the key operations such as restarting devices and clearing database. Before performing the key operations, confirm the operation feasibility, back up data, and prepare the emergency and security measures. Only qualified personnel can perform key operations.

After commands are configured to troubleshoot faults, pay attention to the configuration validation mode to ensure that the configurations take effect. Unless otherwise specified, this manual defaults to the two-phase validation mode.

  • In immediate validation mode, the configuration takes effect immediately after you run a command and press Enter.
  • In two-phase validation mode, you must run the commit command after commands are configured to commit the configuration.

Save the results of each troubleshooting step, so you can provide related information to Huawei technical support if your troubleshooting fails.
