You can upgrade and downgrade the software on the sensor. Upgrading applies a service pack, signature update, signature engine update, minor version, major version, or recovery partition file. Downgrading removes the last applied service pack or signature update from the sensor.
You can recover the application partition image on your sensor if it becomes unusable. Using the recover command lets you retain your host settings while other settings revert to the factory defaults.
To install a new system image on the sensor, use ROMMON, the bootloader file, or the maintenance partition depending on which platform you have.
When you install a new system image on your sensor, all accounts are removed and the default cisco account is reset to use the default password cisco. After installing the system image, you must initialize the sensor again.
After you reimage and initialize your sensor, upgrade your sensor with the most recent service pack, signature update, signature engine update, minor update, major update, and recovery partition file.
