Appendix D Cooling system

CAUTION:
To guarantee heat dissipation, you must install two fan trays of the same model for the switch.
To dissipate heat timely and ensure system stability, the switch uses high-performance cooling
system. Consider the site ventilation design when you plan the installation site for the switch.
The switch uses hot-swappable fan trays. You can provide airflow from the port side to the power
module side or from power module side to the port side by using different types of fan trays.
