# System Requirements

Web Connector can be installed as part of a larger system that includes an IDOL Server and an interface for the information stored in IDOL Server. To maximize performance, Micro Focus recommends that you install IDOL Server and the connector on different machines.

For information about the minimum system requirements required to run IDOL components, including Web Connector, refer to the IDOL Getting Started Guide.

The additional requirements for Web Connector are:

- At least one font must be installed on the connector machine.
- On Linux platforms the Web Connector requires NSS version 3.26 or later.

- On Linux platforms you must install the following dependencies, which are required by the embedded browser:

  CentOS 7 | Debian or Ubuntu
