# Installing policies on Security Engines

Install a policy using the SMC Client to transfer the complete configuration from the Management Server to an Security Engine.

After installation, the Security Engine is ready to start processing traffic. The Security Engines do not receive any clustering settings until the first time you install a policy on them and the working configuration is received from the Management Server. If you do not include a policy in the initial configuration, only the interface used for the control connection with the Management Server is configured after the Security Engine establishes contact with the Management Server.
