Outlet/Socket Specifications
This section explains the power connection specifications of the ETERNUS DX storage systems.
■
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.
●
Frontend Enclosure
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. Power
is supplied from two of the four power sources for each frontend enclosure: FPSU#0 and FPSU#1 for FE#0,
FPSU#2 and FPSU#3 for FE#1. The necessary power can be supplied even if one of the paired power supply units
fails.
●
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.
■
Current Consumption
The following table shows the current consumption (guideline) of each power cord that is used for ETERNUS DX
connections.

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.
