US Patent 10440852 Cable management system in an air-cooled housing

Systems and method for managing cables in a front-to-rear air-cooled housing of a networking system are provided, whereby airflow is controlled to flow through an air filter. According to one embodiment, a network element configured as a cable gate includes a brush and a frame having at least one slot. Each slot is configured to join an interior space of a housing with an exterior space outside the housing. The brush has bristles covering, in an unbiased condition, the at least one slot to reduce air flow between the interior space and the exterior space. The bristles are configured to be displaceable to enable cables to extend through the at least one slot.
