# Add additional nodes to Master Engines

By default, the Master Engine element has two nodes on the Clustering pane of the Engine Editor. You can add new nodes to the Master Engine element. Each Master Engine supports up to 16 nodes.

## Before you begin

Install the additional physical engine device. Connect the cables for at least the interface for communication with the Management Server and the interface for communications between the clustered engines. If the device already has a working configuration from previous use, return it to the initial configuration state in the Security Engine Configuration Wizard on the command line before connecting it to the network. Do not make initial contact with the Management Server before you add the node to the Master Security Engine configuration in the SMC Client.
