CHAPTER 3 Main Unit Power-on/off

For dual power feed configuration
The PRIMEPOWER900 main unit supports a dual power feed configuration using
Fujitsu-supplied options.
When the main unit is connected to two different power supply sources, it can
continue operation even if one of the power supply sources fails.

A dual power feed configuration requires a dual power feed option. If the main
unit without the option mounted is connected to different power supply sources
using multiple power cables, it is not a supported dual power feed configuration.
This option is mounted in the main unit before shipment. Include this option
when placing an order for a main unit. If this option is required after the main
unit has been installed in the field, consult your sales representative.
Use the following information to connect power cables for a dual power feed
configuration:
