Cooling system
The cooling system of the 5500 HI switch comprises the air vents in the chassis, fixed fans, and built-in
fans of power supplies. To guarantee the performance of this cooling system, you must consider the
ventilation design for the installation site when you plan the installation site for the 5500 HI switch.
The 5500 HI switch uses fixed fans and left-right aisles for air ventilation. Ambient air flows in through the
air vents at the left side of chassis (the direction subject to the user facing the front panel of the chassis),
circulates through the chassis and the power supplies, and exhausts at the right side of the chassis and
the air outlet vents of the power supplies. The chassis and power supplies use independent aisles, which
must be kept clear when the switch is operating.
For different switch models, design the cooling system as follows:
