5	UPGRADING A BRIDGE/ROUTER USING
	THE COMMAND-LINE UTILITIES

This chapter describes how to upgrade the software on a bridge/router or switch using the command-line Upgrade Management Utilities. 3Com recommends using the Upgrade Link application described in Chapter 4, but you can use the command-line utilities instead if you want to write scripts or if you do not have a web browser on your NMS. Use Transcend Enterprise Manager or Transcend Network Control Services to upgrade multiple bridge/routers.

You can perform the following types of upgrades:

■Upgrading Software Only

■Automatic Recovery

■Manual Recovery

■Upgrading Hardware and Software

■Automatic Recovery

■Manual Recovery

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.

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