Fujitsu ETERNUS DX100 S4 - Input Power Supply Lines; Figure 18 Dual-Line Power Supply (When Connecting to Power Sockets); Figure 19 Dual-Line Power Supply (When Connecting to a UPS Unit)

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 DX. 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.
