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 cords of the drive enclosures are connected to the power dis-
tribution 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 loca-
tions 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.
