4. 2. 7 Rack-mounted installation
The rack-mounting set A150 or A300 allows the system to be installed horizontally
into a 19” rack. Be sure to observe the following:
• The system takes up the space of 1.5 height units (units) inside the 19” rack.
(1 unit corresponds to 44.45 mm).
• The holes in the mounting plates allow two systems to be placed directly above
each other with a space requirement of three units. Different holes in the mount-
ing plates are used for this purpose (see
Fig. 20 ).
• The space on the left and right between the system and the panels of the 19”
rack is for heat dissipation and must remain clear.
• The installation of a fan is compulsory when rack-mounting an A300; the fan is
included in rack-mounting set A300.
Note: The set of screws for rack mounting always includes fastening screws for
the fan. On the A150 these two screws are superfluous.
