18.8 Notification of a Damaged Recovery Image or
Firmware
The NWA/WAC’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 NWA/WAC 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 NWA/WAC 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 NWA/WAC via a terminal emulation program (such as
HyperTerminal). Your console session displays the NWA/WAC’s startup messages. If you cannot see
any messages, check the terminal emulation program’s settings (see Section 1.2.1 on page 14) and
restart the NWA/WAC.
2 The system startup messages display followed by “Press any key to enter debug mode within 3
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 3 seconds" for more than one minute, go to
Section 18.9 on page 105 to restore the recovery image.
