Airflow Management Blanking Panel Kit with 2U metal panels to prevent airflow recirculation by filling unused rack space (10 pieces). The increasing device density requires better cable management both inside and outside the racks. Poor cable management can lead to damaged cables and additional effort for cable replacement, as well as block airflow or access. The result can be performance losses or even system failures. With this cable management accessory, you can respond to changing requirements at any time. Solutions range from simple cable rings to vertical or horizontal cable organizers, cable trays, and raceways.
