SAFETY WARNING
When using the PoE board at a power level lower or equal to 30W the temperature range
in which you can use this board is equal to the temperature range of the gateway itself (-
30°C to +70°C). However when the PoE board operates at a power level between 30W
and 60W the temperature range is limited to -30°C to +45°C.
When using an AC adapter make sure that the ambient temperature doesn't exceed the
specified temperature limits of the AC adapter.
