Appendix D Cooling System - HPE JH323A Installation Manual

Appendix D Cooling system

The cooling system of the switch includes the air vents in the chassis, fan trays, and built-in fans of
hot swappable power supplies. For correct operation of this cooling system, you must consider the
site ventilation design when you plan the installation site for the switch.
When the fan trays are operating, ambient air flows in through the air vents in the port-side panel and
in the switch sides, circulates through the chassis and the power supplies, and exhausts through the
air vents in the fan tray and power supply panels, as shown in

IMPORTANT:
The chassis and the power supplies use separate air aisles. Make sure both aisles are not blocked.
