After the device is powered on, it runs the BootROM software to initialize the hardware and display the hardware parameters. Then the device runs the system software.

To check the BootROM startup process, you need to connect the Console port of the switch to a terminal by using a serial cable.

The BootROM compares the current configuration with the configuration file. If they are the same, the BootROM asks you whether to reboot the system. The message is as follows:

Info: The system is now comparing the configuration, please wait.

System will reboot! Continue?[Y/N]:y
