Add a deleted Sensor back to the Manager

If you deleted a Sensor from the Manager and want to re-add it, you must reset the shared key value on the Sensor to re-establish secure communication between the Sensor and Manager.

Connect a terminal to the Sensor Console port. (For instructions on connecting to the Console port, see the corresponding Trellix Intrusion Prevention System Sensor Product Guide.)
At the login prompt, log on to the Sensor.
Clear the certificates used for communication with the Sensor. At the prompt, type deinstall.
Type show to see the current configuration information for the Sensor.
Modify it as needed.
Re-enter the shared key information for the Sensor.
At the command prompt, type set sensor sharedsecretkey <WORD>.
This value is used to establish a trust relationship between the Sensor and the Manager. The secret key value can consist of up to 25 characters of any ASCII text. The shared key value is case-sensitive.
Example: set sensor sharedsecretkey IPSkey123.
To exit the session, type exit.
Re-add the Sensor to the Manager as described in Adding a Sensor to the Manager.
