2.4.3 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 DX Disk storage system is maintained.
If the condition above is not satisfied, additional measures are required to ensure sufficient load
bearing capacity. Contact your installation contractor for details about the necessary measures
that must be taken.
2.5 Outlet/Socket Specifications
Power can be supplied to the ETERNUS DX Disk storage system 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.
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 Disk storage system.
This section explains the power connection specifications of the ETERNUS DX Disk storage sys-
tems.
2.5.1 Specifications for Optional Power Supply Products
This section explains the specifications of optional power cords and power related optional prod-
ucts.
When using power distribution units, the number of outlets that are required for controller enclo-
sure and drive enclosure connection should be taken into consideration.
In addition, make sure that the plug type of the power distribution unit fits the power socket when
using an existing power socket. If the plug type does not fit the power socket, replace the socket.
