The Nortel SNAS software image is the executable code running on the
Nortel SNAS. A version of the image ships with the Nortel SNAS and is
preinstalled on the device. As new versions of the image are released, you
can upgrade the software running on your Nortel SNAS. In some cases,
you may need to reinstall the software on the Nortel SNAS in order to
return the device to its factory defaults.
Upgrading the Nortel SNAS
There are two types of upgrades:
• Minor release upgrade: This is typically a bug fix release. All
configuration data is retained. To perform a minor upgrade, connect to
