Rack Mounting
The IMG 2020 can be front-mounted or mid-mounted in a 482.6 mm (19-inch) rack. It is shipped with the brackets in the front mounting position.
The brackets are movable and reversible to accommodate two mid-mounting positions. A front-mounted IMG 2020 requires rear mounting
brackets to secure the back corners.
