Airflow Requirements
The CSG700 series appliance is made of aluminum for optimal heat dissipation.
The appliance has no fans, to minimize noise and to maximize the life of the appliance. Cooling
occurs by natural airflow through the vents on the top of the appliance.
When planning your site for installing a CSG700 series appliance in a 19-inch rack, allow a
minimum of 0.5 RU space above the appliance to allow hot air to flow out of the appliance.
However, itt is recommended that you allow 1 RU space above the appliance for cooling.
When placing a CSG700 series appliance on a desk, ensure that the vents on the top of the unit
are never blocked, to allow hot air to flow out of the appliance. Covering the vents prevents heat
from dissipating out of the appliance, which will cause the chassis to overheat and then shut
down.
