• The rack design must support the total weight of the installed enclosures and incorporate stabilizing
features suitable to prevent the rack from tipping or being pushed over during installation or normal use.
• The rack must not exceed the maximum enclosure operating ambient temperature of 32-degrees C,
using any optical cable or discrete optical transceiver, including all Ethernet cables and InfiniBand
that are >=3 meter in length. However, when you are using the copper cable, the maximum ambient
operating temperature can be 35-degrees C, including all Ethernet and InfiniBand cables < 3 meter in
length.
In particular, the rack front and rear doors must be at least 60% perforated to enable sufficient airflow
through the enclosure. If there is less airflow, additional mechanisms are required to cool the enclosure.
An appropriate IBM rack configuration would be the 7965-S42 IBM Rack Model S42, with standard rear
door and feature code 6069 Front Door For 2.0 Meter Rack (High Perforation).
• The rack must have a safe electrical distribution system. It must provide overcurrent protection for the
enclosure and must not be overloaded by the total number of enclosures installed. The electrical power
consumption rating that is shown on the nameplate should be observed.
• The electrical distribution system must provide a reliable ground for each enclosure in the rack.
• The 7965-S42 rack meet all the requirements and specifications.
Power requirements for each power supply (two per enclosure)
Ensure that your environment meets the following power requirements.

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: 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 IBM Elastic Storage System 3200 enclosure contains two power modules for redundancy. The total
power consumption values represent the total power that is drawn by both power modules.
