Required Number of Outlets/Sockets
The number of power outlets/sockets required to install the ETERNUS AX/HX depends on the number of shelves
and power distribution units.
It is recommended that the power cords of the shelves 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 connect-
ing power cords to power outlets in different racks. It may be necessary to purchase additional power distribution
units depending on the installation locations of shelves.
