Ventilation Requirements

The fans of the device draw air in through the inlet vents on the left and out through the
exhaust vents on the right. The fan tray supports automatic fan speed adjustment and hot-
swapping. To ensure good ventilation, make sure that:
There is a minimum clearance of 10 cm (3.94 in.) around the inlet vents and

exhaust vents for heat dissipation of the router chassis.
A ventilation system is available at the installation site.
