The Adder RMK12 is a 19 inch 1U rackmount kit for 2 x ADDERLink INFINITY 4000 Series units like the ALIF4001R-US (sold separately). It is a tray designed to allow easy or quick installation and removal with shelf space for mounting PSUs and cable management. In order to maintain suitable cooling airflow, if a single module is installed within the rack mount it's recommended to install the optional RMK12-BP blanking plate (sold separately).
