Console Port Setup
You can connect a console (PC, Macintosh, or UNIX workstation) directly to the system via the RS-232 terminal port on the SRP I/O module. 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.
- Click the Start button and select Programs, Accessories, and HyperTerminal.
- In the HyperTerminal window, select HyperTerminal.
- In the Connection Description window, enter a name for your router (for example, erx1400) in the Name field.
- Select any icon to represent your terminal emulation, and click OK.
- In the Connect To dialog screen, in the Connect using field, select the appropriate COM port to use (for example, COM1), and click OK.
- In the COM1 Properties screen, select the following settings:
- Click OK.
Connecting Directly to the ERX System
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. To connect a console directly to the system:
- Connect the female DB-9 connector to the RS-232 port on the system's SRP I/O module. See Figure 5-1.
- Connect the crossover adapter connector to your PC's serial port.
- 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 ERX System Basics Configuration Guide.
Note: Direct access through the RS-232 serial port allows you to monitor the system as it boots.
Assigning an IP Address
When your console is ready to communicate with the system, power up the system (see Chapter 6, Powering Up the System), and set an IP address for the system. The system powers up in User Exec mode. To assign an IP address:
- Enter the enable command at the User Exec prompt.host1>enablehost1#
The system is now in Privileged Exec mode.
- Set an IP address on the Ethernet interface:
- Substitute the slot number where the SRP module is located for the slotnumber variable.
- Use an IP address valid for the system.host1#configure terminalEnter configuration commands, one per line. End with CNTL/Z.host1(config)#interface FastEthernet slotnumber/0host1(config-if)#ip address 10.10.7.3 255.255.255.0
- Continue to configure the system's parameters as needed.
After you have assigned an IP address to the system, you can communicate remotely by running Telnet over an Ethernet network. See the next section, Telnet Setup.
