Mounting

If the CDM-Qx/QxL 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).
