Installing Software When a Firewall Does Not Exist

If there is no firewall between the E-series router and the network host on which you mount the software CD, you can transfer the software release files from the network host to the E-series router via the E-series FTP server or by issuing the copy command. To transfer files via the E-series FTP server, refer to the previous section, Installing Software When a Firewall Exists. This section describes how to transfer files by issuing the copy command.

If you use the copy command to transfer the files, the network host must be an FTP server. This command activates an FTP client on the E-series router.

For this network configuration, you can install the software in the normal command line interface (CLI) operational mode or in boot mode.

Installing Software in Normal Operational Mode

For this procedure, you must access the CLI through either the local console or a Telnet session. If you have not yet configured the E-series router to support Telnet, then you must use the local console. See Chapter 8, Accessing E-Series Routers, 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.

2(For systems that are operating) Stop operation.

3Access the Privileged Exec CLI command mode.

4Configure IP on an interface.

5Configure access to the network host.

6Mount the CD on the network host.

7Copy the software release file to the E-series router.

8Save the current configuration.

9Reboot the system.
