Cooling Requirements

Need for Ventilation

The CVX 600 is a high performance access switch, that produces a significant amount of heat. Providing sufficient cooling ventilation is very important when installing the equipment.

Methods of Cooling

The two typical ways of cooling the equipment are:

•General cooling — cool air is supplied by air conditioning the entire equipment room. Open racks are recommended for general cooling.

•Dedicated cooling — cool air is directly fed to a closed cabinet containing the CVX 600 equipment. If using this method, arrange the cabling so as to minimize its effect on air flow inside the cabinet. Using a fan to move air through the cabinet is recommended, especially if several CVX 600 switches are installed in one cabinet. All cabinet doors should be closed, and all cabinet panels in place.

Airflow

Regardless of the method of cooling used, make sure that minium clearance requirements are met and that airflow at the CVX 600 is at least 200 CFM.
