56 Intel NetStructure Cache Appliance Administrator’s Guide
Viewing and maintaining versions of the software
You can have up to two versions of the appliance software installed on the system
at the same time. From these versions, you can choose which one is current and
executes in the appliance. Installing a new version of the software automatically
makes it the current version.
You can use the versions menu, which is a submenu of the main menu, to do the
following:
✔Identify the installed versions.
✔Install new versions.
✔Switch versions.
✔Delete a version.
✔View which version is running.

Identifying which versions of the software are currently

installed

▼Identifying which versions of the appliance software are installed.
1Select the main menu and press Enter.
2Select versions and press Enter.
3Select view and press Enter. Doing so displays a list of version numbers.

Installing a new version of the appliance software

You can update the software on your cache appliance using FTP to download the
updated files. When you install a new version of the software, it becomes the
current, running version. In addition, the appliance copies the new version to
your secondary drive.
▼Setting up the FTP server
1Set up the FTP server to provide upgrade files to the appliance. You can use a
single FTP server to upgrade multiple appliances.
2Place the files on an FTP server that’s accessible by the appliance, and on a
network with sufficient performance for fast transfer of files.
3Each upgrade must exist in a separate directory. We recommend that the
names you choose for your directories indicate the release. This example
shows separate directories for application, patch, and OS/application
upgrades:
<ftp_dir>/app_3.0.9.0
<ftp_dir>/app_3.1.0.0
<ftp_dir>/patch_1
<ftp_dir>/patch_2
<ftp_dir>/os_1
<ftp_dir>/os_2
