 Related Information

This document contains a step−by−step procedure for upgrading your Cisco NI−2 DSLAM. A TFTP server or
a remote copy protocol (RCP) server application must be installed on a TCP/IP ready workstation. Once the
application is installed, a minimal level of configuration must be performed. First, the TFTP application must
be configured to operate as a TFTP server, not as a TFTP client. Second, the outbound file directory must be
specified. This is the directory in which the Cisco IOS

®

 Software images are stored. Most TFTP applications

provide a setup routine to assist in these configuration tasks.

For more information on document conventions, see the Cisco Technical Tips Conventions.

There are no specific prerequisites for this document.

This document is not restricted to specific software and hardware versions.

Use the following procedure to upgrade the Cisco IOS Software image.

Install the new Cisco IOS Software image in the outbound directory of the TFTP server.

The TFTP server looks for the DSLAM's Cisco IOS Software image in this directory. Make sure that
the image you want to copy to your Flash is in this directory.

Memory requirements for each image are also in the outbound directory of the TFTP server. Using
the show version command, verify that you have enough memory.
