CDM-570/570L Satellite Modem with Optional IP Module Revision 4
Installation MN/CDM570L.IOM
2.2 Mounting
If the CDM-570/570L is to be mounted in a rack, ensure that there is adequate clearance
for ventilation, particularly at the sides. In rack systems where there is high heat
dissipation, forced air cooling must be provided by top or bottom mounted fans or
blowers. Under no circumstance should the highest internal rack temperature be allowed
to exceed 50°C (122°F).
IMPORTANT
The CDM-570/570L CANNOT have rack slides mounted to the side of
the chassis. Two cooling fans are mounted on the right-hand side of the
unit. However, Comtech EF Data recommends that an alternate method of
support within the rack be employed, such as rack shelves. If there is any
doubt, please consult the Comtech EF Data Customer Support department.
