A **grandMA2 replay unit (RPU)** is considered as a console in the system.

It has the same software and capabilities as the consoles. It is a 19" 3 Unit rack-mount version of the console, without all the user interface and physical controls. It has almost the same connectors on the rear panel as a console (with fewer USB connectors).

It functions exactly like a console in the system.
