6.2. Mains Connection
Figure 18: Inserting the power cables
The storage subsystem is supplied with the mains voltage via the two delivered power cables.
Plug the end of the power cables marked (1) into the port of the power supply
unit on the rear panel of the storage subsystem.
Plug the end of the power cables marked (2) into a safety socket on the rack mains socket strip.
CAUTION!
Ensure that at least one power supply unit of the 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 mains 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.
