Connecting to the CLI Locally

If you plan to use the CLI to configure the router, you must connect through the console port, as shown in Figure 56 and Figure 57.

Note: Figure 56 and Figure 57 show a connection to a local management device. A remote connection to the router through a modem requires the cable and connector shown (provided in the router's accessory box), plus a DB-9 female to DB-25 male (or similar) adapter for your modem, which you must purchase separately.

To connect to the CLI using a local management device through the console port on the router:

1. Turn off power to the router.
2. Turn off the power to the management device, such as a PC or laptop computer, that you are using to access the CLI.
3. Plug one end of the Ethernet cable supplied with your router into the RJ-45 to DB-9 serial port adapter supplied with your router (see Figure 57).
4. Plug the RJ-45 to DB-9 serial port adapter into the serial port on the management device (see Figure 57).
5. Connect the other end of the Ethernet cable to the console port on the router (Figure 57).
6. Turn on the power to the management device.
7. Start your asynchronous terminal emulation application (such as Microsoft Windows Hyperterminal) and select the appropriate COM port to use (for example, COM1).
8. Configure the port settings as follows:
   • Bits per second: 9600
   • Data bits: 8
   • Parity: None
   • Stop bits: 1
   • Flow control: None
9. Power on the router by pressing the power button on the front panel. Verify that the POWER LED on the front panel turns green.

   The terminal emulation screen on your management device displays the boot sequence. When the router has finished booting, a login prompt appears.

10. Log in as the user root. No password is required at initial connection, but you must assign a root password before committing any configuration settings.
