Appendix D Cooling system
To dissipate heat timely and enhance system stability, the switch uses a high-performance cooling
system. Consider the site ventilation design when you plan the installation site for the switch.
The switch uses removable fan trays. They provide airflow from the port side to the power supply
side or from power supply side to the port side by using different types of fan trays. You must install
all fan trays of the same model for the switch.
