58.8 Notification of a Damaged Recovery Image or
Firmware
The UAG’s recovery image and/or firmware could be damaged, for example by the power going off
during a firmware upgrade. This section describes how the UAG notifies you of a damaged recovery
image or firmware file. Use this section if your device has stopped responding for an extended
period of time and you cannot access or ping it. Note that the UAG does not respond while starting
up. It takes less than five minutes to start up with the default configuration, but the start up time
increases with the complexity of your configuration.
1
Use a console cable and connect to the UAG via a terminal emulation program (such as
HyperTerminal). Your console session displays the UAG’s startup messages. If you cannot see any
messages, check the terminal emulation program’s settings (see
) and
restart the UAG.
2
The system startup messages display followed by “Press any key to enter debug mode within 1
seconds.”
Note: Do not press any keys at this point. Wait to see what displays next.

3
If the console session displays “Invalid Firmware”, or “Invalid Recovery Image”, or the console
freezes at "Press any key to enter debug mode within 1 seconds" for more than one minute, go to
to restore the recovery image.
