NOTICE
Do not cover the ventilation grilles
During installation, select a mounting position so that the ventilation grilles are always free to
achieve adequate cooling. With normal orientation, the ventilation grilles are on the top,
bottom and sides of the housing.
If you install more than one rack device, make sure that the permitted ambient conditions are
met for all devices in the rack.
Minimum clearances
If you install the IE Switch in rack devices without forced ventilation or cooling, minimum
clearances must be maintained to neighboring devices or the wall of the enclosure. By keeping
to the minimum clearances, there is then an adequate stream of air for heat dissipation during
operation. Keep to the following minimum clearances to neighboring devices.
