Outlet/Socket Specifications

This section explains the power connection specifications of the ETERNUS DX storage systems.

■

Power Supply Units

Power can be supplied from two power sources in the ETERNUS DX 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 (such as whether power distribution units are used or not and input voltage) are not

used for the ETERNUS DX.

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.

1.7.1

Specifications for Optional Power Supply Products

This section explains the specifications of optional power cords and power related optional products.

For power distribution units, the number of outlets that are required to connect the controller enclosure and

drive enclosures should be taken into consideration, and the most appropriate power distribution units

should then be selected.

When an existing power socket is used, make sure that the plug type of the power distribution unit fits the

existing power socket and that the power supply facility is able to provide sufficient power to the system. If

the plug type does not fit the power socket, electrical work to change the power socket is required. This elec-

trical work must be performed in compliance with the electrical codes of the nation, the municipality, or the

region.
