UPGRADING USING THE NETBUILDER

4 UPGRADE LINK APPLICATION

This chapter describes how to upgrade the software on a NETBuilder bridge/router or a PathBuilder switch using the Upgrade Link application. Upgrade Link is an easy to use GUI for the upgrade utilities that runs in a web server. Access to the server is available via a web browser. If you are upgrading multiple bridge/routers, you should use Transcend Enterprise Manager or Transcend Network Control Services instead. Contact your network supplier for more information about Transcend. Or if you want to write scripts, you can use the command-line utilities as described in Chapter 5. Use the command-line utilities if you do not have a web browser on your network management station (NMS).

An NMS is a UNIX or Windows system that has a FTP/TFTP server running in addition to software, such as the Upgrade Management Utilities, to manage your network. For Windows, the utilities include the 3Com FTP/TFTP server called 3CServer.

Preparing for the Upgrade

Before upgrading your system, confirm the following items:

■You have installed the utilities according to Chapter 2.

■You have set the path for the utilities (UNIX only). If you have not set the path, complete the following step for your UNIX shell:

■For a C-shell installation, add the contents of the following file to the .cshrc file for each user you want to have access to the utilities, including root:

/usr/3Com/common/data/.login-bcm

Or you can enter the path after every logon:

source /usr/3Com/common/data/.login-bcm

■For a Bourne shell installation, add the contents of the following file to the

.profile file for each user you want to have access to the utilities, including root:

/usr/3Com/common/data/.profile-bcm

Or you can enter the path after every logon:

. /usr/3Com/common/data/.profile-bcm

■All configuration files are in the same directory as the boot image.

■You have booted your bridge/router from the primary boot source.

■You have a web browser installed with Java support, such as Netscape Navigator 4.5 or Internet Explorer 4.x, and you have it in your path (UNIX).

CAUTION: Only one client at a time should access the Upgrade Link Server.

■There is sufficient disk space on the NMS for the amount of software you are installing.
