Figure 36: The firmware update failure page 
In the unfortunate event that the firmware upgrade fails, the ‘Failed verification. File is 
most likely corrupt’ or similar message will appear in the Verify file integrity row. No 
changes will be made to the system and the general message File verification failed 
appears. 
9.1.7  Verify the firmware has been upgraded successfully 
To check the firmware version, in the top menu, browse to System -> Flash 
Operations, or after router reboots, in the top menu, click Status. The Firmware 
Version shows in the system list and also in the right top corner of the menu bar.
