After starting a switch through the BIOS menu, you can log in to the switch through the console interface without entering the password only this time. The original console interface login password is still saved in the configuration file.

1.Connect the PC to the console interface of the switch and restart the switch. When the following information is displayed, press Ctrl+B within 3 seconds and enter the BIOS password to enter the BIOS menu. Select Modify console password and enter y. The switch will restart.
Press CTRL+B to enter BIOS menu: 1

Password: //The default BIOS password is
Info: The entered password is the same as the default one. You are advised to change the password to ensure security.

BIOS Menu (Version: 333)

1. Continue to boot
2. Update from serial interface
3. Update from ethernet interface
4. Modify startup parameters
5. File system
6. Modify stack parameters
7. Modify BIOS password
8. Modify console password
9. Restore factory defaults
10. Reboot

Enter your choice(1-10): 8

Caution: A new console password must be set after the restart.
