Finally, the AX3000 is automatically reset and the new firmware is enabled. 
IMPORTANT: The AX3000 IP layer, used for the tftp protocol, does not handle 
the fragmentation/defragmentation process. Therefore, if a router fragments 
frames (mtu lower than 600 bytes), the AX3000 will not be able to perform the 
download. 
If any problems occur, see the next section.

This section discusses possible problems. The error list is not exhaustive ; if an
