The storage subsystem is supplied with the power supply voltage via
the four delivered power cables.

Figure 20: Connecting the four power cables to two power supply lines


Plug one end of the power cables into the port of the power supply
unit on the rear panel of the storage subsystem.

Plug the other end of the power cables into a safety socket on the rack
power supply socket strip.
Ensure that at least one power supply unit of the Storage
i
Subsystem and one power supply unit of the server attached to
the subsystem are connected with the same phase.
In order to set up the power supply connection of the storage
subsystem with phase redundancy, the two power supply units
must be connected to two different phases or to two different
circuits of the rack installation.
Ensure that the safety sockets used to connect the storage
subsystem are protected sufficiently by a 16 A or 15 A (USA)
automatic cutout.
