CHAPTER 14
14.1
Maintenance and Diagnostics
This chapter describes how to perform a software upgrade, configuration backup, or configuration
restoration, and how to use the diagnostic functions of the router.
Software Upgrade and Configuration Backup /Restoration
The router supports TFTP upgrade via the console, Telnet, and Web browser. Using a TFTP server, you
can upgrade the software, back up the configuration, and retrieve past configurations. This section
describes how to achieve these tasks using the console port or LAN port.
In the above diagram, the TFTP server is a PC with TFTP software installed. If you will use the console
port to perform the TFTP upgrade, connect the console port of the router to your PC. If you will use Telnet
or Web browser, connect the LAN port of the router to your Ethernet LAN.
Notes:
After the home page is upgraded, right-click your Internet Explorer shortcut icon on your desktop and
choose Properties on the popup menu. On the Internet Properties window, click on the Clear History
button and click OK. Then you can use the Web browser to log on to the router.
