1. ETERNUS DX Installation
Outlet/Socket Specifications

Required Number of Outlets/Sockets

The number of power outlets/sockets required to install the ETERNUS DX depends on the number of enclosures
and power distribution units.
It is recommended that the power cords of the 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 connect-
ing power cords to power outlets in different racks. It may be necessary to purchase additional power distribu-
tion units depending on the installation locations of enclosures.
■
Without Power Distribution Units
Four power sockets are required for each frontend enclosure.
Two power sockets are required for every controller enclosure, 2.5" type drive enclosure, and 3.5" type drive en-
closure.
■
With Power Distribution Units
Two power sockets are required for each power distribution unit.

Circuit Protectors

Protection coordination must be secured between the distribution board circuit protectors and the ETERNUS DX
or power distribution units to protect the ETERNUS DX by blocking the failed circuit immediately when a power
supply input error occurs.
Distribution board circuit protectors must satisfy the following required conditions and breaking characteristics.
■
Required Conditions
The distribution board circuit protectors must satisfy the required conditions that are listed below.
