Use the following procedure to edit the hostname or IP address of the managing appliance. You can also 
change the display name of the managing appliance, which is a name only used within the context of the 
FireSIGHT System. Although you can use the hostname as the display name of the appliance, entering 
a different display name does not change the hostname.

Note that you cannot add devices running software more than one major version lower than the Defense 
Center. For example, if your Defense Center is running Version 5.3.0, you can add devices running 5.2.x 
or higher but not devices running 5.1.x.

You can click the slider to block the communication channel between the managed device and the 
Defense Center. Click the slider to re-enable the communication channel.
