Input Power Supply Lines

Use multiple power supply facilities in the building or multiple UPS units for power supply redundancy, and divide the AC input system for the ETERNUS DX into a dual system (line 0 and line 1).

Because the power supply of the ETERNUS DX is configured redundantly, 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 (including the server). When selecting a single configuration, take into consideration the availability of the system.

Note

When the power distribution units are separately connected to line 0 (PSU#0) and line 1 (PSU#1), the availability of the power supply facilities is improved.
