Logging In to the CX310 BIOS

Scenarios

Log in to the CX310 BIOS through the CX310 serial port.

The BIOS can be accessed only from the switching plane CLI after you log in to the CLI over a serial port.

The BIOS initializes hardware, such as serial ports or dual in-line memory modules (DIMMs), reads the kernel image from the flash memory to the random access memory (RAM), and starts the operating system (OS). In the BIOS, you can load underlying software and debug underlying devices.

Procedure

1. You have logged in to the converged switching plane CLI over a serial port.
2. Log in to the CX310 BIOS.
   1. Run the following command on the CLI of the converged switching plane to restart the converged switching plane:

      <HUAWEI> reboot

      The command output is as follows:

      Warning: Current configuration will be saved to the next startup saved-configuration file! Continue? [Y/N]:

      Enter Y to save the configuration. The command output is as follows:

      Now saving the current configuration.

      begin synchronize configuration to SMM ...                                       
      slot 4: configuration is the same with SMM, needn't sync to SMM.                                
                                                                                       
      System will reboot! Continue? [Y/N]:     

      Enter Y to restart the converged switching plane.

   2. Press Ctrl+B when the system displays "Press CTRL+B to enter BIOS menu".

      The command output is as follows:

      Password:

   3. Enter the BIOS login password.

      The BIOS menu screen is displayed:

      BIOS Menu (Version: 017) 
       
           1. Continue to boot 
           2. Update from serial interface 
           3. Update from ethernet interface 
           4. Modify startup parameters 
           5. File system 
           6. Modify BIOS password 
           7. Modify console password 
           8. Reboot
