Reinitializing the Sensor

Reinitializing the sensor is an important process to understand. The OS of the sensor can become corrupt simply from shutting down incorrectly. The sensor is an Intel-based Solaris platform and proper procedures must be followed. Also, if the sensor is used, or the password and configuration is unknown, you may want to reinitialize to get a fresh build. There is basically three ways to reinitialize the sensor or recover the image. You can download the image from Cisco.com, use the recovery CD supplied with the sensor, or uninstall/roll back to a previous version. Regardless of the method you use, make sure you have documented the configuration thoroughly. This will expedite the recovery or reinitialization process
