First Login Through the Console Port

Procedure

1. Connect the switch to a PC using a console cable. The RJ45 connector connects to the switch's console port, and the DB9 connector connects to the PC's serial port (COM), as shown in Figure 4-1.

   If a maintenance terminal (PC) does not have a DB9 serial port, purchase a USB-to-DB9 cable that has a DB9 male connector with nuts. Connect the DB9 female connector of the console cable to the DB9 male connector, and connect the USB connector to the USB port of the maintenance terminal.

2. Start the terminal emulation software on the PC. Create a connection, select the connection port, and set communication parameters.

   Ensure that the communication parameters you set in the terminal emulation software are consistent with the default parameter settings of the switch's console port. Table 4-1 describes the default parameter settings of the switch's console port.
