Lighthouse is Opengear's central management software, supplied as a software appliance (VM). It both manages Opengear devices (Console Servers, Resilience Gateways, etc.) directly, and provides management access to connected network & IT infrastructure (routers, switches, PDUs, servers, etc.), from a central, highly-available point.
While each Opengear device is fully self-contained to enable out-of-band management of a rack, row or closet, combined with Lighthouse they become a comprehensive, resilient management solution that scales up in the data center and out to remote sites.
Node: A Node is a device that can be enrolled with Lighthouse, allowing it to be accessed, managed, and monitored – see this article for a list of devices that can be enrolled as Nodes.
Managed Device: A Managed Device is a device that is managed via a Node through a Serial, USB, or Network connection.
Lighthouse VPN: Lighthouse VPN is the OpenVPN based connections that the Lighthouse instance has with the Opengear Nodes it is managing.
