The solution to the backplane failure

If the external power supply is normal, but the internal modules of the switch are not working properly, it may be that the backplane is broken. There is no other solution to this fault. There is only one solution, and that is to replace the backplane, because it cannot be repaired. In order to effectively prevent the occurrence of such failures, the most important thing is to provide the switch with a working environment that meets the standard specifications provided by the manufacturer.
