Each SAS expansion enclosure contains two PSUs for redundancy. The total power consumption values
represent the total power that is drawn by both PSUs.
Environmental requirements
System airflow is from the front to the rear of each enclosure:
• Airflow passes between drive carriers and through each enclosure.
• Airflow for the upper 4U of the 5U enclosure enters the front, passes between the disk drives, and exits
through the large fans in the rear of the enclosure.
• Airflow for the lower 1U of the 5U enclosure is driven through the power supplies via 40mm X 56mm
fans. Air continues through the chassis cooling the ESMs or controllers and exits the rear of the
enclosure.
• The combined power and cooling module exhausts air from the rear of each canister.
Ensure that your environment falls within the ranges that are shown in Table 29 on page 104.
