Introduction 2-3
If MSH chassis are mounted one above the other, there must be
adequate space between them for cooling air to pass. When
fitted, the cable support tray, which can be ordered from your
local LinkBuilder supplier, provides the correct spacing between
units. If you do not fit a cable support tray you should leave 1U
between units. (The height of standard 19 inch rack mountings
are measured in `U's. 1U is approximately 45 millimeters (1
3
/
4
”).)
If you decide to install the chassis into a 19 inch rack, you can also
determine which face of the chassis is the front. Throughout this
user guide, we assume that the front of the chassis is that face
which has the network connections and module LEDs. However,
you may find that, for your set-up, it is more convenient to have
all cable connections at the back of the unit.
Fitting The Mounting Brackets
