This document explains how to install Cisco IOS® software using a TFTP server or Remote Copy Protocol
(RCP) server application. This document also explains the procedure for upgrading your software image on
access servers.

To use the troubleshooting tools described in this document, you must be a registered user and you
must be logged in.

• 

A TFTP server or an RCP server application must be installed on a TCP/IP−ready workstation or PC.
Once the application is installed, a minimal level of configuration must be performed by following the
steps listed below:

Configure the TFTP application to operate as a TFTP server as opposed to a TFTP client.

1. 

Specify the outbound file directory. This is the directory in which the Cisco IOS software
images are stored (see step 2 below). Most TFTP applications provide a set−up routine to
assist in these configuration tasks.

Note: A number of TFTP or RCP applications are available from independent software
vendors or as shareware from public sources on the World Wide Web.

2. 

Download the Cisco IOS software image into your workstation or PC from the Download Software
Area.

Make sure the newly downloaded image supports your hardware, has the required software features,
and that your router has enough memory to run this image. If you do not yet have a Cisco IOS
software image, or if you are not sure the image you have meets all the necessary requirements, refer
to How to Choose a Cisco IOS® Software Release.
