2.2 Mounting
If the CDM-700 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-700 has short rear support brackets mounted to the side of the
chassis - two cooling fans are mounted on the right-hand side of the unit.
