UPGRADING THE SOFTWARE IMAGE
O
NLY
An image-only upgrade is an upgrade that replaces the NETBuilder bridge/router
or PathBuilder S5xx series switch boot image file but does not upgrade any
configuration files. You can perform an image-only upgrade in the following
cases:
■ You are installing a patch release for your current version of software.
■ You are upgrading to a different package of the same version.
■ Your new version does not require updated configuration files (for example,
10.1 to 10.3).
■ You are upgrading a PathBuilder S5xx series switch.
You can upgrade:
■ Using Upgrade Link
■ Using the Command-Line Utilities
■ Using the Enterprise OS User Interface
You can also use Transcend Enterprise Manager or Transcend Network Control
Services to perform an image-only upgrade. See the guide that came with
Transcend for more information.
3Com recommends using the utilities instead of the Enterprise OS user interface.
The utilities automatically back up the software and perform all the necessary
copying and boot source settings automatically.
Preparing for the
Upgrade
If you are using Upgrade Link or the command-line, 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:
