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.
