34.3.3 GDL 39/GDL 39R/GDL 5XR Software Update
GDL software updates are loaded through the GDU. After the steps in Section 34.3.1 have been
completed, the GDU will identify the software version currently in use for the GDL and compare it to the
GDL software version stored in internal GDU memory. If the current GDL software is different than the
GDL software stored in GDU memory, the GDU will automatically begin updating the GDL. An
"Updating..." indication for the GDL (and for any LRU being updated) is displayed on the Main
Configuration page. Another indication of the update is found on the Data Link Information Page (normal
mode). Allow the update to complete. After the update, the GDL will resume normal operation.
CAUTION
It is critical that GDU power is not removed during the software update. An
interruption in supplied power or turning the unit off during the SW update may
damage the GDL causing it to be non-functional.
