Restoring Default Configuration (Factory Reset)
Very rarely, it may become necessary to run the “factory-reset” script on your system. This reinstalls the 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

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:

■
A text file containing just the 16-character Release Key, named rk
■
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 (or via a direct connection to the appliance with a
keyboard and monitor). 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.
