2.6.2 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 cords of the drive enclosures are connected to the power distribution units
that are 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 necessary 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.
Table 2.10 Required number of outlets and sockets to install power distribution units
