Cooling system
Fan trays of the routers are hot swappable and support automatic fan speed adjustment. To ensure
good ventilation, the following requirements must be met:
•
Leave a minimum clearance of 10 cm (3.94 in) at the inlet and outlet air vents.
•
The installation site has a good cooling system.
The HSR6802 and HSR6804 routers use the same airflow design.
