Installing Software When a Firewall Does Not Exist

Installing Software in Normal Operational Mode

module, and reinitialize. When you observe the LEDs on the line modules, the line
modules appear to boot twice.
If there is no firewall between the router and the network host to which you copied the
release files, you can transfer the software release files from the network host to the
router via the FTP server or by issuing the copy command. To transfer files via the FTP
server, refer to the previous section, "Installing Software When a Firewall Exists" on
page 119. 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 router.
For this network configuration, you can install the software in the normal command line
interface (CLI) operational mode or in boot 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 router to support Telnet, then you must use
the local console.
To install the software, perform the following tasks. (See Table 13 on page 124.)

Table 13: Software Installation Procedure When a Firewall Does Not Exist

1. Obtain the required information for the installation.
2. For routers that are currently operating, divert network traffic to another
router.
3. Access the Privileged Exec CLI command mode.
4. Configure IP on an interface.
5. Configure access to the network host.
6. Copy the release files to the network host.
7. Copy the software release file to the router.
8. Save the current configuration.
9. Reboot the system.

Task 1: Obtain the Required Information

Before you install the software, obtain the following information:
The password (if one is configured) that enables you to access Privileged Exec mode
on the router
The IP address of the network host
The IP address of the router
The IP address of the next hop to reach the destination network (for example, a
gateway)
