2.5.2 Required Number of Outlets/Sockets
The number of power outlets/sockets required to install the ETERNUS DX Disk storage system
depends on the number of drive enclosures and power distribution units.
It is recommended that the power cord of a drive enclosure is connected to the power distribution
unit that is installed in the same rack. Secure the necessary number of power outlets within the
same rack to avoid connecting power cords to power outlets in different racks. It may be neces-
sary to purchase additional power distribution units depending on the installation locations of
enclosures.
■ Without power distribution units
Two power sockets are required for each enclosure (controller enclosure and drive enclosure).
■ With power distribution units
Two power sockets are required for each power distribution unit. There are three types of power
distribution units. The size and number of outlets are different for each type.
