You can connect a console terminal (PC, Macintosh, or UNIX workstation) directly to the SRP I/O module via the RS-232 terminal port. When you connect a console directly to the system, you can configure the system without an IP address.
To communicate with the system, you must have a terminal emulation program running on your PC or Macintosh. You can use any terminal emulation program, such as HyperTerminal. A UNIX workstation can use the emulator TIP.
If your console uses a version of Microsoft Windows (such as Windows 95 or Windows NT 4.0) that supports the HyperTerminal application, you can access the system via HyperTerminal.
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:

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.
Direct access through the RS-232 serial port enables you to monitor the system while it boots.
When your console is ready to communicate with the system, power up the system. (See Powering Up ERX Routers.) Then set an IP address for the system. The system powers up in User Exec mode. To assign an IP address:
The system is now in Privileged Exec mode.
After you have assigned an IP address to the system, you can communicate remotely by running Telnet over an Ethernet network. See Telnet Setup.
