HPE 5510 HI Series

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 Figure 58.
