Power Supply Connection
The storage subsystem is supplied with the power supply voltage via the four
delivered power cables.
Figure 25: Connecting the four power cables to two power supply lines
Ê
Plug one end of the power cables into the port of the power supply unit on
the rear panel of the storage subsystem.
Ê
Plug the other end of the power cables into a safety socket on the rack power
supply socket strip.
I
Ensure that at least one power supply unit of the ETERNUS JX40 S2
storage 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.
