6.1 Upgrading the Licensing SD Card in a Module
The advanced functions, such as video and audio processing, on AHP video/audio input and
output modules are enabled by the Snell Licensing system. Licenses are enabled on a
module by module basis allowing you to choose only the functions required for each input and
output module in your router. The license information for each module is held on the licensing
SD card that is plugged into the front of each module.
Before starting this procedure make sure that you have the correct Licensing SD card(s)
ready.
1. Open the router door.
2. Open the front fan assembly to access the modules. This will expose the module the
SD card is to be fitted to.
3. Push the SD card currently in the module until it clicks then let go. The card will come
out enough for you to pull it out of the carrier.
4. Replace the original SD card with the new licensing SD card by pushing it into the SD
card slot until it clicks.
5. Close the fan assembly ensuring that no wires are trapped.
6. Close the router door.
7. Confirm the status of the licenses on the module(s) by looking at the “Module
Licensing Status” screen on the door screen, this can be found from the Modules
screen. See the Sirius 800 User manual for details.
8. The new licensed features can now be configured in Workbench. For details of the
licensed options available for each module see the Sirius 800 User manual.
• The fan assembly should be placed back into the closed position as soon as
possible after opening, as this ensures correct ventilation of the frame. Failure to
do this will result in failure.
• In practice the maximum time that a fan assembly can be left open will depend on a
number of factors such as; ambient temperature, frame loading, crosspoint
routings, etc. To ensure correct operation under all conditions the fan assemblies
should be left open for no more than 4 minutes at a time.
• If the SD card is removed from a module for more than 30 minutes the licensed
options will cease to function on that module. Routing will not be affected but
remember that if any processing functions such as; mixing, shuffle, gain, Frame
Sync, Delay, etc are in use they will be reset to their default values. Replacing the
licensing SD card will re-instate the licensed options.
