Huawei Fiber Optic Switch Serial Port Configuration
To configure a Huawei fiber optic switch via the serial port, connect through a console cable, set terminal software to 9600 baud, no flow control, and ensure the correct driver is installed.
Connecting to the Serial Port
- Physical Connection: Use the console cable provided with the switch. If your PC lacks a serial port, a USB-to-serial adapter can be used. Some Huawei switches also support Mini USB console connections .
- Terminal Software: Popular options include SecureCRT, PuTTY, or IPOP. Open the software and select the correct COM port corresponding to your connection .
- Driver Installation: Ensure the serial-to-USB adapter driver is correctly installed. Check in Device Manager; a yellow warning indicates a missing or faulty driver, which must be reinstalled .
Terminal Settings
- Baud Rate: 9600 (default)
- Data Bits: 8
- Parity: None
- Stop Bits: 1
- Flow Control: Disabled These settings allow proper communication with the switch console .
Accessing the Switch
- Launch the terminal software and connect to the switch.
- Press Enter to access the login prompt.
- Log in using the switch's credentials.
- Enter system view to configure interfaces, VLANs, or other switch parameters .

Tips
- If using a USB-to-serial adapter, always verify the COM port number in Device Manager before connecting.
- Disable flow control in the terminal software to avoid communication issues.
- For switches with Mini USB ports, use the Mini USB cable and the same terminal settings. By following these steps, you can reliably configure and manage Huawei fiber optic switches through the serial console port.
