H.3.3 GDL 39/GDL 39R Software Update
GDL 39/39R software updates are loaded through the GDU. After the steps in Appendix H.3.1
have been
completed, the GDU will identify the software version currently in use for the GDL 39/39R and compare it
to the GDL 39/39R software version stored in internal GDU memory. If the current GDL 39/39R software
is different than the GDL 39/39R software stored in GDU memory, the GDU will automatically begin
updating the GDL 39/39R. An "Updating..." indication for the GDL 39/39R (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 39/
39R 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 39/
39R causing it to be non-functional.
