Heat Dissipation
The QSW-4600-28ТX full gigabit switch is designed with fans. To ensure good dissipation, sufficient space (10 cm
distance from both sides and the back panel of the chassis) should be reserved for ventilation. It is recommended to clean
the switch at regular intervals (like once every 3 months). Especially, avoid dust from blocking the screen mesh on the
back of the cabinet; otherwise, the temperature of the device may go too high and affects the performance.
When installing the device, sufficient ventilation space (1 U (44.45 mm) distance from the adjacent device) should be
reserved for the purpose of heat dissipation.
