The Vertiv Geist SwitchAir- SA2-004 is an active 2U airflow management device for 1U switches with air intake on front (port) side. Channels provide a dedicated path for cold aisle air to flow to the intake of the switch, using the on-board fans to push cool air from the cold aisle to the intake of the switch. The SwitchAir also creates a barrier preventing recirculation of hot exhaust air from the hot aisle from entering switch intakes.
