[0002] With the continuous advancement of technology, the application scenarios of smart chassis are becoming increasingly diverse, and users' needs for chassis controllers are also evolving. However, many chassis controller products on the market have not kept up with this trend, but have blindly pursued intelligence and modularity. This has led to the configuration of many unused modules in the chassis controller, which occupies valuable chassis space and increases costs and complexity. At the same time, existing chassis controllers are usually unable to achieve power-off restart of multiple loads, which limits users' ability to remotely manage and maintain devices inside the chassis.
