1.7 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.
●
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.

Current Rating
The following table shows the rating of the current for each power cord that is used for enclosure connec-
tions.

For power distribution units, make sure that the total rating of the currents for all of the power supply units
that are to be connected does not exceed the normal usage rating of the power distribution unit.
