Installing System Images
Recovering the Application Partition Image
To recover the application partition image, follow these steps:
Step 1
Download the recovery partition image file to an FTP, HTTP, or HTTPS server that is accessible from
your sensor.
Step 2
Log in to the CLI using an account with administrator privileges.
Step 3
Enter configuration mode.
sensor# configure terminal
Step 4
Recover the application partition image.
sensor(config)# recover application-partition
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 mus t 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.

Installing System Images
Caution
All user configuration settings are lost when you install the system image. Before trying to recover the
sensor by installing the system image, try to recover by using the recover application-partition
command or by selecting the recovery partition during sensor bootup.
