2.8.2 Dual power feed


2.8.2 Dual power feed
Dual power feed is an option for receiving power feeds from two external power supplies. If a failure occurs in one external power supply, the system can still continue to operate with the external power supply on the other system.

Figure 2-15 and Figure 2-16 show a power supply system with dual power feed.

For dual system connections, connect the power cords to the input power supplies on separate systems.

*1 For expansion rack 2, use PDU#3.
*2 For expansion rack 2, use PDU#2.
*3 Each PDU outlet is connected to the power cord shown in the figure. The system consumes no power when there is no device connected to the PDU outlets. For the wiring of power cords within the expansion rack, see Figure 2-22.
