If this fault occurs, perform the following steps to locate the fault (save operation records):

Step 1: Enter the BIOS menu and view the system flash directory to check whether the switch contains the system software package (with the file name extension .cc).

Take system software package CE12800-V100R002C00SPC200.cc as an example. The operation procedure is as follows:

Press CTRL+B to enter BIOS menu:    //Press CTRL+B to enter the BIOS menu.

Password: //Enter the BIOS password. The default password is Admin@huawei.com. In V200R019C00 and later versions, if the default password is used, you need to change the password

        BIOS Menu (Version: 221)

     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        //This option is not supported in V200R019C00 and later versions. 
     8. Reboot

Enter your choice(1-8): 5

In the file system submenu, select 3. Return to return to the BIOS menu.

Step 2: Check and modify system startup parameters, and specify the system software package in the flash directory as the next startup file.
  1. Check the current startup file. The operation procedure is as follows:
            BIOS Menu (Version: 221)
    
         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
    
    Enter your choice(1-8): 4
    
            Startup Submenu
    
         1. Display current startup configuration
         2. Modify startup configuration
         3. Return
    
    Enter your choice(1-3): 1
    Current boot disk    : flash
    Current startup file : <NULL>
    Current config file  : <NULL>
  2. Modify system startup parameters. The operation procedure is as follows:
            Startup Submenu
    
         1. Display current startup configuration
         2. Modify startup configuration
         3. Return
    
    Enter your choice(1-3): 2
    '.' = clear field;  Ctrl+C = quit; Enter = use current configuration
    
    Current startup file is "<NULL>", modify the file name if needed.
    Input the new file name: CE12800-V100R002C00SPC200.cc      //Specify the next startup file.
    The startup file has been modified from "<NULL>" to "CE12800-V100R002C00SPC200.cc".
    
    Current config file is "<NULL>", modify the file name if needed.
    Input the new file name:       //Retain the original configuration file and press Enter to return to the startup submenu.
    
            Startup Submenu
    
         1. Display current startup configuration
         2. Modify startup configuration
         3. Return
    
    Enter your choice(1-3): 1     //Check whether the startup file is successfully changed.
    Current boot disk    : flash
    Current startup file : CE12800-V100R002C00SPC200.cc
    Current config file  : <NULL>

    Select 3. Return to return to the BIOS menu.

Step 3: In the BIOS menu, select 8. Reboot to restart the switch and observe the BIOS display to check whether the switch can start normally. If not, go to step 4.

Step 4: If the flash memory does not contain the system software package, or the MPU still fails to restart after the path is reconfigured, reload the system software package. The operation procedure is as follows:

Log in to Huawei enterprise technical support website to download the system software package of the corresponding version and load it on the switch. After loading the system software package, check whether the switch starts normally.

Step 5: If the MPU still fails to start or register after the system software package is reloaded, the MPU is faulty. Collect the following information and send the information to technical support personnel.
  1. Collect operation records on the serial interface or network interface, and save the records in a text file.

  2. Collect user logs and diagnostic logs. For details, see How Do I Collect Logs of a Device?.

  3. Observe the blue E-USB storage indicator in the inner left side of the MPU panel. The indicator can be steady on, blink fast, blink slowly, or be off.

  4. After collecting the preceding information, connect the serial cable to another MPU. The switch restarts normally. After entering the command line interface, run the power { off | on } slot slot-id command in the user view or system view to power off and then power on the faulty MPU and check whether the switch starts normally.

    To prevent information loss, power off the MPU after collecting the preceding information.
