Impact on the System

  • The controller fails to be powered on. System reliability may be reduced.
  • The engine where the faulty controller resides loses redundancy protection. When the system write protection policy is enabled (enabled by default) and the system continues to work for more than the preset time (192 hours by default), the system enters the write protection mode.

Possible Causes

The exception in the power-on process causes the power-on failure.

Procedure

  1. Check whether an effective error code exists in the detailed information.

    1. If yes, find the troubleshooting measures according to the prompted error code.
    2. If no=> Step2.

  2. Collect the log information and contact technical support engineers to rectify the fault.

    1. If the write protection policy is enabled and the fault cannot be rectified within the preset period, run the "change system write_policy write_policy write_protect_time=xxx" command to change the effective period of the write protection policy. The engine has no redundancy protection, which may cause data reliability risks. Rectify the fault as soon as possible.
    2. If the system has entered the write protection mode but services need to be restored as soon as possible, run the "change system write_policy write_protect_switch=Disable" command to disable the write protection function of the system. The engine has no redundancy protection, which may cause data reliability risks. Rectify the fault as soon as possible. After the fault is rectified, restore the write protection function of the system in time.
