6.2.3 Firmware Upgrade Process
• It is recommended that the modules in the router are updated in a logical manner to
ensure that all modules are updated and it is suggested that upgrades are carried out
in the following order; output modules, input modules and finally crosspoint modules.
• Update one module at a time and do not remove any SD card for more than
30 minutes.
• Double check that the firmware being copied to the SD card matches the module type
that is being upgraded and that it also matches the licensed features purchased for
the module.
1. Before starting make sure you have extracted the upgrade folders to your computer,
see section 6.2.1 for details.
2. Open the router door.
3. Open the front fan assembly to access the module to be updated.
4. Push the SD card currently in the module until it clicks then let go. The card will be
released enough for you to pull it out of the carrier.
5. Remove the SD card and close the fan assembly.

• 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.
