Input Power Supply Lines

Multiple power supply facilities in the building or multiple UPS units are recommended for power supply redun-
dancy. A redundant configuration is used for the power supply of the ETERNUS AF. Business can continue even if
one of the power supply lines fails.
However, a single power supply facility configuration is also allowed for the entire system optimization (includ-
ing the server). When selecting a single configuration, take into consideration the availability of the system.
