Outlet/Socket Specifications
This section explains the power connection specifications of the ETERNUS AB/HB storage systems.
■ Power Supply Units
The ETERNUS AB/HB has multiple power supply units in each of its shelf.
Using the same power requirements for all the power supply units is recommended so that the
power requirements (use of power distribution units and input voltage) do not vary in the ETERNUS
AB/HB.
● Controller Shelves and Drive Shelves
Power can be supplied from two power sources because each shelf has two power supply units.
During normal operation, each of the power sources supplies half of the necessary power.
If either of the power supply lines fails, all of the necessary power is supplied from the other
power source.
■ Current Consumption
The following table shows the current consumption (guideline) of each power cord that is used for
ETERNUS AB/HB connections.
Table 22 Maximum Current Consumption of Each Power Cord
-: Incompatible with AC100V
When power distribution units are used, make sure that the current capacity totaling the maximum
current consumption value of power cords that connect to the shelves does not exceed the maxi-
mum current consumption value of the power distribution unit.
