The procedures outlined in the following sections provide detailed instructions for typical installations. For additional information about commands and troubleshooting, refer to theERX System Basics Configuration Guide and the ERX Command Reference Guide.
Installing Software When a Firewall Exists
When a firewall separates the ERX system from the network host, you must FTP the software release files from the network host to the ERX system. In this case, you must configure the FTP server on the ERX system and ensure that FTP client software is installed on the network host.
For this network configuration, you must install the software from the normal operational mode of the command line interface (CLI). You can access the CLI through either the local console or a Telnet session. If you have not yet configured the ERX system to support Telnet, then you must use the local console. See Chapter 5, Accessing the ERX System, for information on using a local console or a Telnet session.
To install the software, perform the following tasks:
1Obtain the required information for the installation.
2Access the Privileged Exec CLI command mode.
3Configure IP on an interface.
4Mount the CD on the network host.
5Configure access to the network host.
6Enable the FTP server on the ERX system.
7Identify the files to transfer.
8Transfer the files to the user space on the ERX system.
