Rack-mount Bracket Holes Four rack-mount bracket screw holes on each side
Switches in the series have a built-in temperature sensor that measures the internal
temperature of the switch and then automatically adjusts the speed of the fans to
high-speed or low-speed, or turns them off.
Switches startup with fans at low speed. If the ambient temperature is under 35 °C,
the fans function at low speed. If the ambient temperature is above 40 °C, the fans
function at high speed.
