Operating the Router 35
Software Release 2.4.1
C613-02021-00 REV B
To change the install information in the router, enter the command:
SET INSTALL={TEMPORARY|PREFERRED|DEFAULT}
[RELEASE={release-name|EPROM}] [PATCH=patch-name]
For security reasons the SET INSTALL command is only accepted if the user has
SECURITY OFFICER privilege.
When you set a patch file as part of a temporary install or permanent install,
you must also set the corresponding release file in the same command, if it has
not already been set as part of that install. You can set the patch, but not the
release (always EPROM), for the default install.
To delete a temporary install or preferred install, enter the command:
DELETE INSTALL={TEMPORARY|PREFERRED}
If a default install is set, only the patch information is deleted using the
DELETE INSTALL command as the release information must always be left
intact in the default install.
To display the current install information, including which install is currently
running in the router, and how the install information was checked at the last
reboot, enter the command:
SHOW INSTALL
For more information about INSTALL commands, see the Operations chapter in
the AR400 Series Router Software Reference.
Example: Upgrade to a New Software Release Using
TFTP
This example assumes the router is correctly configured to allow TFTP to
function. This means that IP is configured and the router is able to
communicate with the designated TFTP server. The TFTP server is assumed to
function correctly and the release and patch files are assumed present in the
server’s TFTP directory. The router has no release or patch files, and is running
the EPROM Software Release 2.3.2. The IP address of the server is 172.16.1.1.
The name of the release file being loaded is
52-241.rez.
To upgrade to a new software release:
1. Configure the LOADER.
The LOADER module is set up with defaults to make the process of
downloading files in future simpler. All release and patch files in this
router are stored in FLASH.
SET LOADER METHOD=TFTP SERVER=172.16.1.1 DEST=FLASH
2. Load the new release file onto the router.
Make sure there is space in FLASH for the new release file. Load the new
file onto your router. Make sure the release file matches your router model
(see “Upgrading Router Software” on page 34). Load any patch files
required, and the help file for the release (see “Loading and Uploading Files”
on page 30). To load the release file using your LOADER default settings,
enter the command:
LOAD FILE=52-241.rez
