The front and rear mounting brackets listed in
If the distance between the front and rear mounting rails in a cabinet is out of the ranges listed in
5-5, use a tray together with the front mounting brackets. To install your switch in a DC cabinet (1000
mm or 1200 mm deep), separately purchase rear mounting brackets (part number: 21240537) dedicated

Determine the installation position of the switch and use a flat-head screwdriver to install
two floating nuts on each front mounting rail accordingly. Leave a gap of 1 U between
the two floating nuts and ensure that they are level with those on the other front
mounting rail.
Install two floating nuts on each rear mounting rail. Leave a gap of 1 U between the two
floating nuts. Ensure that the lower floating nuts on the four mounting rails are level with
one another.
