Appendix G: Technical Specifications ● 149Environmental SpecificationsNote: Adaptec RAID controllers require adequate airflow to operate reliably. The recommendedairflow is 200 LFM (linear feet per minute). Forced airflow is recommended.Note: Ambient temperature is measured 1” from RAID processor.DC Power RequirementsCurrent RequirementsAmbient temperature with forced airflow 0 °C to 55 ° CAmbient temperature with Battery Backup Unit (BBU) 11 BBU is not supported on all controllers.
