Revision 4 

Installation 

MN/CDM570L.IOM 

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). 
 

 

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. 

 

Install optional installation bracket (Figure 2-1) using mounting kit, KT/6228-2.
