A system of thermally managing network equipment including a rack housing a network equipment element, an intake coupling including one or more vanes and an exhaust port, a duct, and a rack coupling mechanism configured to adjustably position the intake coupling relative to the rack. The intake coupling is configured to: receive an airflow from the hot air exhaust vent at a first direction; deflect the airflow in a second direction via the one or more vanes; and exhaust the airflow through an opening in the exhaust port.
