Procedure

1. Connect the DB9 connector of the prepared console cable to the PC's serial port (COM), and the RJ45 connector to the device's console port. If there is no DB9 serial port on your terminal (PC), use a DB9-to-USB cable to connect the USB port to the terminal.
2. Start PuTTY on the PC (PuTTY is an example terminal emulator). Create a connection, select the connection port, and set communication parameters.
   1. Click Session to create a connection, as shown in Figure 2-1.
      Figure 2-1 Creating a connection
      

   2. Click Serial and set the port to be connected and the communication parameters, as shown in Figure 2-2.
      1. Select the port according to your requirements. For example, in a Windows operating system, you can open Device Manager to view port information and select the port to be connected.
      2. Ensure that the communication parameters you set in the terminal emulation software are consistent with the default parameter settings of the device's console port.
      3. Click Open.

      A PC may have multiple ports that can be connected to the device. In this step, the port to be connected to a console cable must be selected. In most cases, COM1 is used.

      If the device's communication parameters are modified, those on the PC must be modified accordingly and the connection must be re-established.

   • You must set a login password upon first login to the device through the console port. After the login is successful, the console port has the default administrator rights.

   • The password is a string of 8 to 16 case-sensitive characters. It must contain at least two of the following character types: uppercase letters, lowercase letters, digits, and special characters. Special characters do not include question marks (?) or spaces.

   • In interactive mode, the entered password is not displayed on the terminal screen.

   • For security purposes, change the password periodically.

   After completing the preceding steps, you can run commands to configure the device. Enter a question mark (?) whenever you need help.
