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.
