How to solve the backplane failure?

The various modules of the switch are plugged into the backplane. If the environment is humid, the circuit board is short-circuited by moisture, or the components are damaged due to high temperature, lightning strikes, etc., the circuit board will not work properly. For example: poor heat dissipation performance or too high ambient temperature causes the temperature inside the machine to rise, causing the components to burn out. In the case of normal power supply from the external power supply, if the various internal modules of the switch do not work normally, it may be that the backplane is broken. In this case, even electrical maintenance engineers may have nothing to do. The only way is to replace the backplane.
