The HP X722 fan tray, part 5060-0174, is a cooling assembly for network switch hardware. It moves air through the chassis along a defined front-to-back path.
Its airflow runs from the port side toward the power-supply side. Matching this direction to the switch’s cooling layout helps maintain the intended airflow through the equipment.
The listed switch configuration uses two fan tray assemblies. This part is identified as the X722 port-to-power fan tray.
