This product is designed to facilitate better airflow management in your server rack . It creates an airduct between the rack face and the short device air intake. The entire design is meant to facilitate the blocking of hot air from recirculating to the cold face of the rack.
You can actually access SwitchFix units in myriad sizes and configurations to match specific network devices. What more? They are also backed by field adjustability to match different rack dimensions and mounting rail positions. SwitchFix models are available in 1U and 2U heights coupled with front, rear, and side intake/exhaust configurations.
