2.1 Rack installation
2.1.1 Installing rack mounting rails
The UXF Cradle can be mounted in most standard 19-inch video or IT rack types. The unit
needs two rack units (2 RU) of vertical space in the rack.
Install two L-shaped rack mounting rails (not supplied) that match your rack type. Refer to the
documentation of your mounting rails or rack for installation instructions.
• Make sure that both front and back end of the rails are attached to the rack. Allow a
minimum distance of 30 cm (11.8 in.) between the secured points.
• There should be a blind/untapped area in the front of the vertical rack beam where the
locking mechanism of the XCU engages the rack.
• The thickness of the horizontal leg of the L-shaped mounting rails must not exceed 2 mm
(0.08
in.) in order to leave enough space for more cradles to be mounted below the unit.
Below is an example of a rack mounting rail installed in a 19-inch rack. Note that your specific
situation may be different.
min. 30 cm (11.8 in.)
min. 12 mm (0.5 in.)
max. 2 mm (0.08 in.)
