5.5 Installing the SCM4000
Each installation or deployment will have its own specific tasks
according to the application and the installed hardware. The
following sections describe mounting and cabling the SCM4000.
For fixed applications, the SCM4000 can be mounted in a
standard 19-inch (48.3 cm) rack. The cabling is permanently
installed and power comes from the facility or site power source.
For mobile applications, the SCM4000 is usually mounted in a
bulkhead or compartment 19-inch (48.3 cm) rack and the cabling
is permanently installed. Power comes from the mobile power
source.
The following requirements are designed to make initial
installation easier and to allow room for future access and
servicing.
5.5.1 Equipment Rack
The SCM4000 mounts into the mounting rails of a standard 19-
inch (48.3 cm) equipment rack. It occupies 1 rack unit (1RU) of
height.
CAUTION Do not overload the rack or load it unevenly.
Secure the rack to a solid surface.
• Make certain the rack and mounting rails are strong and
rigid enough to support the SCM4000 and the rest of the
equipment in the rack.
• It is recommended that a rack mount shelf be installed in
the back of the rack to support the SCM4000 during high
stresses during vehicle operation.
• The rack should be securely attached to a solid surface
such as a floor or wall to prevent movement or tipping
over.
• Position the rack to allow easy access to the front and
rear of the equipment.
• Be sure to allow room behind the equipment rack for the
many cables required. The cables should not be pressed
against the rear of the equipment when closing doors.
This will stress the cables and may shorten their life.
5.5.2 Mounting the SCM4000
Mounting the SCM4000 into an equipment rack is easier if one
person holds the unit while another person installs the mounting
screws.
