Installing Your Controller and Expansion Units in a Rackmount
Installing Your Controller and Expansion Units
in a Rackmount
Your controller and expansion units were designed to be installed in
19-inch rackmounts only. They will not fit into 23-inch racks.
Each unit has a side fan and a rear cooling fan. Mount or position your units
so that air can circulate freely around them. When operating the units,
select a location that provides at least:

75 mm (3 in.) of rear clearance

25 mm (1 in.) of side clearance (left and right)
Note: There is no need to leave an empty slot between units when you stack
them one on top of the other inside a rackmount.
Install your controller and expansion units into a rackmount kit before
inserting them into a rack.
C
AUTION
Failure to provide adequate cooling clearance may result in an
excessive internal temperature, thus reducing the reliability of your
units.

High-speed units bear the “HS” inscription on their front panels,
while the standard units do not.

You can link both high-speed and standard units. However, to
benefit from the high-speed feature, you must chain the units
in a specific order: all the high-speed units first, followed by all
the standard units.
