1. ETERNUS AF Installation

Outlet/Socket Specifications

Installation Methods

Perform one of the following rack installation methods to ensure the safe use of an ETERNUS AF 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 AF is maintained.
(Load bearing capacity of the floor) > (ETERNUS AF 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.
Outlet/Socket Specifications
This section explains the power connection specifications of the ETERNUS AF storage systems.
■
Power Supply Units
Power can be supplied from two power sources in the ETERNUS AF 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.
Using the same power supply condition for all of the power supply units is recommended so that different power
supply conditions (input voltage) are not used for the ETERNUS AF.
■
Current Consumption
The following table shows the current consumption (guideline) of each power cord that is used for the connec-
tions to each type of enclosure.

When using power distribution units, make sure that the current capacity totaling the current consumption val-
ue of power cords that connect to the enclosures does not exceed the actual usage rating of the power distribu-
tion unit.
