Specifications
Environmental
The EPC-6320/21 meets the following environmental specifications.
CAUTION
• Use the EPC-6320/21 only with compatible UL Listed computers that have installation instructions
that details user installation of card cage accessories.
• Ensure that the operating environment provides sufficient airflow (200 LFM) across the CPU board
to keep it within its temperature specification. Failure to provide sufficient airflow may result in
CPU failure.
Note
The maximum temperature decreases when the relative humidity exceeds 30%.
