5.1 Rack installation
Install the unit on a plane surface or in your rack. For 19" (483 mm) rack installation, 3 units are required.
When mounting the unit into the rack, please make sure that there is enough space around the device so
that the heated air can be passed on. Steady overheating will damage your device. You can fix the unit with
four screws M6 in the rack.
