FIRMWARE UPDATE & RECOVERY
14. Firmware Update & Recovery
In this chapter we explain the firmware upgrade process and where to get firmware files. We also discuss the procedure for
recovering to a previous firmware version or resetting the username & password if it is ever necessary.
NOTE: The Fiber Optic Transmitter card DVFTXM and Distribution Amplifier DV2DA do not
appear in the GUI and are not affected by any firmware or upgrades.
New system firmware for the DVIS platform is provided in an archive file format of .tgz in a zip container and will be made
available from time to time. It is not necessary to un-compress the tgz package as the DVIS has built-in facilities to accept
the file in tgz format. The tgz file is provided from ATX Networks support in a zip format, so it will be necessary to un-zip the
file downloaded first. The name of the zip file and the tgz file inside will be the same except for the extension and both will
be named with the firmware version number. If you require a program to unzip the file, an open source file archiver may be

14.2 Types of Firmware Files
A brief description of the files that may be obtained.
14.2.1 System Upgrade/Recovery File
This is a file that is used to bring the DVIS up to the latest firmware revision and is referred to as a firmware upgrade. This file
may be used even if the equipment has a very old version of firmware installed as it completely replaces all files on the DVIS
platform and works with any previously installed version. This file can also be used to reinstall the latest firmware revision on
an already upgraded device if there is suspicion that the firmware might not be working as expected and this application of the
same file would be referred to as a system recovery. This is the most commonly installed file type and is installed in the same
manner regardless of the end requirement. The following attributes apply to this file type:
•
Can be used to upgrade any firmware version or when existing version is unknown.
•
Fully replaces existing firmware.
•
Suitable only when unit is physically available (cannot be applied remotely).
•
Used to recover network parameters, login credentials or after mis-configuration.
•
IP parameters and login passwords are reset to factory default.
•
Requires full re-configuration of all channel parameters.
14.2.2 Remote Upgrade
This file type may be applied to the equipment even if it is remotely located. This firmware may be installed over a limited range
of previous firmware so check the support site for qualifying existing versions.
•
Usable for minor firmware changes. Check the support site for qualifying existing versions.
•
Suitable when the unit is remotely located.
•
IP parameters and login credentials are not changed.
•
Channel parameters are not changed.
