Installing System Images
Warning: Executing this command will stop all applications and re-image the node to
version 7.1(x)E4. All configuration changes except for network settings will be reset to
default.
Continue with recovery? []:
Step 5 Enter yes to continue. Shutdown begins immediately after you execute the recover command. Shutdown
can take a while, and you will still have access to the CLI, but access will be terminated without warning.
The application partition is reimaged using the image stored on the recovery partition. You must now
initialize the sensor with the setup command.The IP address, netmask, access lists, time zone, and offset
are saved and applied to the reimaged application partition. If you executed the recover
application-partition command remotely, you can SSH to the sensor with the default username and
password (cisco/cisco) and then initialize the sensor again with the setup command. You cannot use
Telnet until you initialize the sensor because Telnet is disabled by default.

command or by selecting the recovery partition during sensor bootup.
