Connecting a Terminal or PC to the Console Port
Connect a terminal or PC to the Console port either to configure the software by using the CLI or to 
troubleshoot problems with the router. 
To connect a terminal or PC to the console port on the router and access the CLI, follow these steps:
Step 1 Connect the RJ-45 end of a DB-9-to-RJ-45 serial cable to the RJ-45 Console port on the router. 
Figure 3-3 shows the RJ-45 end of the serial cable connected to the Console port on the router.

Step 2 Connect the DB-9 end of the DB-9-to-RJ-45 serial cable to the COM port on your laptop or PC.
Note Some laptops and PCs do not come with DB-9 serial port connectors and may require a 
USB-to-serial port adapter.
Step 3 To communicate with the router, start a terminal emulator application.
