Installation Methods

Perform one of the following rack installation methods to ensure the safe use of an ETERNUS DX that is instal-
•
led in a rack:
To secure a rack, use a rack without stabilizers and secure it to the building with the leveling feet.
-
- If a rack is not to be secured, make sure to use a rack with stabilizers and use these stabilizers to prevent the
rack from toppling over.
• Which installation method should be used depends on the installation location, the floor conditions, and the
type of racks that are to be used. Contact your installation contractor for more details regarding installation
and how the installation should actually be performed.

Load Bearing Capacity for Floors

Make sure that the following relationship between the load bearing capacity of the floor and the weight of the
ETERNUS DX is maintained.
(Load bearing capacity of the floor) > (ETERNUS DX weight ¸ Installation area that includes service areas)
If the condition above is not satisfied, additional measures are required to ensure sufficient load bearing capaci-
ty.
Contact your installation contractor for details about the necessary measures that must be taken.

Power Supply Units
The ETERNUS DX has multiple power supply units in each of its enclosure.
Using the same power supply condition for all of the power supply units is recommended so that different power
supply conditions (such as whether power distribution units are used or not and input voltage) are not used for
the ETERNUS DX.
●
Controller Enclosures, 2.5" Type Drive Enclosures, and 3.5" Type Drive Enclosures
Power can be supplied from two power sources because each enclosure has two power supply units.
During normal operation, each of the power sources supplies half of the necessary power.
When one of the power supply lines fails, all of the necessary power is supplied from only one power source.
●
High-Density Drive Enclosures
Power can be supplied from four power sources because each enclosure has four power supply units.
During normal operation, each power source supplies a quarter of the necessary power.
If any of the power supply lines fails, all of the necessary power is supplied from the other power sources. The
necessary power can be supplied even when two power supply units fail.
