Logging In to a Device for the First Time Through a Mini USB Port

Logging In to a Device for the First Time Through a Mini USB Port

If no console port is available on your PC, you can use a mini USB cable to connect a USB port on the PC to the mini USB port of a device that is being powered on for the first time. After that, you can perform basic configuration on the device and manage the device.

Pre-configuration Tasks

Before logging in to a device through the mini USB port, complete the following tasks:

  • Power on the device.
  • Prepare a mini USB cable. (You can use type-B mini USB cable, which is not delivered with the device.)
  • Obtain the mini USB driver that is compatible with the PC's operating system.

    To obtain the mini USB driver, visit and select AR_MiniUSB_driver to download. The mini USB driver supports only Windows XP, Windows Vista, and Windows 7 operating systems.

  • Installing the terminal emulation software on the PC

    You can use the self-contained terminal emulation software of the operating system (such as the HyperTerminal of Windows 2000) on the PC. If no built-in terminal emulation software is available, use the third-party terminal emulation software. For details, see the software user guide or online help.

Default Settings

Table 8-2  Default settings for the mini USB port
Parameter Default Setting
Baud rate 9600 bit/s
Flow control None
Parity None
Stop bits 1
Data bits 8


  1. Install the mini USB driver on the PC.
    1. Use a mini USB cable to connect a PC USB port to the mini USB port of the device.

      If you reinstall the mini USB cable or manually terminate the serial connection when using the mini USB port, open a new serial connection window after the serial connection is restored. The original serial connection window is invalid.

    2. As shown in Figure 8-4, double-click the driver installation file on the PC and click Next.

      Figure 8-4  Running a driver on the PC

    3. As shown in Figure 8-5, select I accept the terms in the license agreement and click Next.

      Figure 8-5  Accepting the terms in the license agreement

    4. As shown in Figure 8-6, click Change to change the driver directory, and click Next.

      Figure 8-6  Specifying the driver directory

    5. As shown in Figure 8-7, click Install and decompress the driver. When the system finishes decompressing the driver, click Finish.

    6. Find the DISK1 folder in the file decompression path specified in step d, and double-click setup.exe in the folder.
    7. Click Next. Select I accept the terms in the license agreement and click Next to install the driver.
    8. Click Finish to finish installing the driver. Right-click Computer, and choose Manage > Device Manager > Ports(COM&LPT). The system displays TUSB3410 Device indicating the driver that has been installed.

      If there is no TUSB3410 Device in the device manager, reinstall the driver or use another mini USB cable to connect the device to the PC.

  2. Start the terminal emulation software on the PC. Create a connection, select the connected port, and set communication parameters. (This section uses the third-party software SecureCRT as an example.)
    1. Click to establish a connection, as shown in Figure 8-8.

      Figure 8-8  Establishing a connection

    2. Set the connected port and communication parameters, as shown in Figure 8-9.

      Select the connected port based on actual situations. For example, you can view port information in Device Manager in the Windows operating system, and select the connected port.

      Communication parameters of the terminal emulation software must be consistent with the default attribute settings of the console user interface on the device, which are 9600 bit/s baud rate, 8 data bits, 1 stop bit, no parity check, and no flow control.

      By default, no flow control mode is configured on the device. Because RTS/CTS is selected in the software by default, you need to deselect RTS/CTS; otherwise, you cannot enter commands.

      If you modify the serial port communication parameters on the device, you must make the same modifications on the PC and then create a connection again.

  3. Click Connect. The following information is displayed. Enter the password. The default user name is admin, and the default password is Admin@huawei.(The following information is only for reference.) For details about the default password for the device, see What Is the Default Login Password?.

    Login authentication                                                            
    Info: The entered password is the same as the default. You are advised to change
     it to ensure security. 
    • The password entered in interactive mode is not displayed on the screen.
    • You are advised to change the password after login and update the password regularly to ensure security.
    • If the configuration file contains a plain-text password or the entered password is an encryption password with low security, the system displays the message "There are security risks in the configuration file. You are advised to save the configuration immediately. If you choose to save, the current configuration file will be unavailable after version downgrade. Are you sure to save now?[y/n]:" when you log in to the device.
      • If you need to save the current configuration, enter y and press Enter.
      • If you do not need to save the current configuration, enter n and press Enter. It is recommended that you enter y.
    • When you connect to a new or unconfigured device through a console port, the following information is displayed:

      Auto-Config is working. Before configuring the device, stop Auto-Config. If you perform configurations when Auto-Config is running, the DHCP, routing, DNS, and VTY configurations will be lost. Do you want to stop Auto-Config? [y/n]:

      • To continue Auto-Config, enter n and press Enter.
      • To stop Auto-Config, enter y and press Enter.

    You can run commands to configure the device. Enter a question mark (?) whenever you need help.
