software image and resets the configuration to the functional minimum.
Note: Restoring default configuration causes the system to use its current default values, which may be
different from the previously configured values, particularly if the system has been upgraded from an older
version. In particular this may affect port settings, such as multiplexed media ports. After restoring default
configuration you may want to reset those port settings to match the expected behavior of your firewall.

Prerequisite Files
The factory-reset procedure described below rebuilds the system based on the most recent
successfully-installed software image. The files that are used for this reinstallation are stored in the
/mnt/harddisk/factory-reset/ folder on the system. These files are:

n
A text file containing just the 16-character Release Key, named rk
n
A file containing the software image in tar.gz format, named tandberg-image.tar.gz
In some cases (most commonly a fresh VM installation that has not been upgraded), these files will not be
present on the system. If so, these files must first be put in place using SCP as root.

Performing a Reset to Default Configuration
The following procedure must be performed from the serial console. This is because the network settings will
be rewritten, so any SSH session used to initiate the reset would be dropped and the output of the procedure
would not be seen.
