Connecting Directly to the Router

When you connect a console directly to the system, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the system.

The console port is considered a data terminal equipment interface (DTE). Direct connection to a terminal or PC (which also have DTE interfaces) requires a crossover cable.

To connect a console directly to the system:

1. Connect the female DB-9 connector to the RS-232 port on the system's SRP I/O module. See Figure 36.

   Figure 36: Management Ports for ERX Routers

   

2. Connect the crossover adapter connector to your PC's serial port.
3. Power up the system.

   When you power up the system, the CLI appears on your console's screen. The system is now in User Exec mode, and you can begin configuration. For more information on using the CLI and configuring the system, see the JUNOSe System Basics Configuration Guide.

   Note: Direct access through the RS-232 serial port enables you to monitor the system while it boots.
