NSTALLATION Mechanical The RX-1 CORE Telemetry Receiver can be mounted in a standard 19” rack with 20” depth, with 1U total occupation. Thanks to its powerful air flow extraction from front to back, there is no specific requirement to leave a free 1U rack space above and below it.
Page 28: Standard 19" Rack Integration
The RX-1 has been designed to be integrated in a standard 19” rack. Because of its weight, it is necessary that the RX-1 rests on brackets in the Bay. Four holes (  M6x16CB ) are available at the front to fix the unit to the rack.
