2.2 Mounting
If the demodulator 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 demodulator
CANNOT
have rack slides mounted to the side of the chassis.
Two cooling fans are installed in the right-hand side of the unit. Comtech EF Data
therefore recommends that an alternate method of support, such as rack shelves, is
employed within the rack. If there is any doubt, please consult the Comtech EF Data
Customer Support department.
