1.7.2 Required Number of Outlets/Sockets
The number of power outlets/sockets required to install the ETERNUS DX 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.
