Ambient temperature limitations
The following table lists configurations that require ambient temperature less than
35°C.
Note
The ambient temperature limit must be adhered to ensure proper cooling and to avoid
excess processor throttling, which may impact appliance performance.
The following table describes the configurations required with ambient temperature
restriction.
