Note: These measurements are presented as an example. Measurements that are obtained in other
operating environments might vary. Conduct your own testing to determine specific measurements for
your environment.
Each Model 092 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.
• The combined power and cooling module exhausts air from the rear of each canister.
Ensure that your environment falls within the ranges that are listed in Table 8 on page 28.

Note:
• – Max Ambient Temperature Environment = 32C / 950 m
– Max Altitude Environment = 25C / 3,050 m
– Decrease the maximum air temperature by 1 degree C per 300 m above 950 m.
• The maximum ambient operating temperature when using an optical cable or discrete optical
transceiver is 32C, which includes all Ethernet (100Gb) cables and InfiniBand (100Gb EDR) that are
