Loading Failure Troubleshooting
If the loading process fails, the system will continue to operate in its original state. In such a situation, users
should first verify the physical port connections to ensure they are properly connected. If some ports are
disconnected, reconnect them before attempting to reload the system. If the physical connections are secure,
the next step is to examine the loading process information shown on the super terminal. If any input errors
are detected, they should be corrected before reloading the system.

1.
Connect the console port of the switch to a computer using a console cable.
2.
Press "ctrl + b" to access the Uboot mode.Start the system with an
