- Introduction
  An overview of Arc Embedded.
- Requirements
  The machine and network requirements necessary to use Arc.
- Preparation
  Information on how to import Arc packages, and install a license.
  - Arc licenses
    Before you can deploy and use Arc, you will need to buy a license. How Arc licenses are installed will depend on the existing installation that you have. Arc and Arc Embedded require separate licenses.
  - Install a license in Guardian or CMC
    Before you can use Arc you must install the applicable license.
  - Import Arc through the update service in Guardian or CMC
    Before you can deploy Arc, you must import it first. There are two methods you can use to do this, one method is through the Nozomi Networks Update Service. The alternative method is through a manual contents upload.

  - Local services
    It is important to understand the different local services that are necessary for the different operating systems.
  - User permissions
    Arc collects a diverse set of information from the hosting machine, and can take control of the network interfaces. To grant full functionality, Administration/root permissions are needed.
  - Connectivity
    Arc connects to Guardian and Vantage through designated protocols and ports.
  - Hardware setup for Mitsubishi Electric MELSEC iQ-R PLC

  - Hardware setup for Schneider Electric SCADAPack 47xi RTU
    The recommended physical setup for the Schneider Electric SCADAPack 47xi remote terminal unit (RTU).
- Configuration
  Details on how to configure Arc.
- Deployment
  Information on how to deploy Arc. This includes details for manual and automatic deployments, and deployment through a mobile device management (MDM) system.
- Execution
  Information on the different modes that you can use with Arc.

During Automatic deployment, dependencies are also installed. To install the dependencies manually, download them and install them individually. Alternatively, you can use a mobile device management (MDM) tool to install them across the managed network.

is never installed by default on any platform. On Windows it can be installed through the Arc setup when connected to Vantage. On Linux and macOS, needs to be downloaded from the Arc dependencies page on Vantage and installed manually. Arc detects an existing installation automatically on any platform.
