To aid in power and cooling requirements planning, the following table lists the rating of each power
module by enclosure.
The power that is used by the system depends on various factors, including the number of enclosures and
drives in the system and the ambient temperature.

Note: The data in Table 7 on page 31 and Table 8 on page 32 measurements are presented as an
example. Measurements that are obtained in other operating environments might vary. Conduct your own
testing to determine specic measurements for your environment.
Each IBM Storage Scale System 3500 enclosure contains two power modules for redundancy. The
total power consumption values represent the total power that is drawn by both power modules when
operating together or a single power module when operating in a maintenance or failure mode.
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 the following table.

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 (100 Gb) cables and InniBand (100 Gb EDR) that are
greater than or equal to 3 meter in length.
