• The rack design must support the total weight of the installed enclosures. Incorporate stabilizing
features suitable to prevent the rack from tipping or being pushed over during installation or normal
use.
• The rack design must consider the maximum enclosure operating ambient temperature of 35-degrees C
(95-degrees Fahrenheit).
• 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. Observer the
electrical power consumption rating that is shown on the nameplate.
• The electrical distribution system must provide a reliable ground for each enclosure in the rack.
Power requirements for each power supply
To aid in power and cooling requirements planning, Table 7 on page 6 lists the rating of each power
supply unit (PSU) by enclosure. Each enclosure contains two AC PSUs for redundancy. The power rating
values represent the total power that is drawn by both PSUs. 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: One or more C19 power distribution units (PDU) are needed in the rack to connect power to the
power supplies of the 5U expansion enclosure.
The measurements that are shown in the following tables were obtained in the specific operating
environment and under the conditions described. These measurements are presented as an illustration;
measurements that are obtained in other operating environments might vary. Conduct your own testing to
determine specific measurements for your environment.
Table 8 on page 6 shows examples of the power ratings of Storwize V5000E systems with different
drive configurations.
